A California man made violent threats against leaders of an organic industry watchdog group based in southwest Wisconsin
Vernon County Sheriff’s Office identified 23-year-old Gabriel Ramirez of Santa Cruz
California as the source of several threatening emails and a threatening phone call made to staff at the La Farge-based nonprofit OrganicEye
Ramirez was employed at the time by California Certified Organic Farmers
the nation’s largest USDA-accredited organic certification service
Ramirez began sending the messages in November 2023, shortly after OrganicEye filed a formal complaint with the National Organic Program over alleged conflicts of interest at CCOF
The watchdog group claimed CCOF had not effectively separated its certification service from the group’s nonprofit foundation. The group claimed that could allow major national organic brands to use charitable donations to the foundation to sway the company’s decisions around organic certification
said he’s been threatened with lawsuits before over the group’s investigations into alleged misconduct in the organic industry
But these messages threatened violence against himself and his family
as well as other OrganicEye employees and their families
“I’ve been doing this for over 20 years
and this is the first threat of violence we’ve received,” Kastel said
A sheriff’s department investigator was able to get a search warrant for phone records related to a threatening call made in February 2024
The investigator traced the call to a personal cellphone belonging to Ramirez
Sheriff Roy Torgerson said both Ramirez and his employer cooperated with his department’s investigation
His department has referred the case to Vernon County District Attorney Angela Palmer-Fisher for review
including a potential felony charge of threats to injure
“Just completing the investigation and identifying the source sends a very loud message to our community that we don’t tolerate this type of behavior,” Torgerson said
I don’t know if it’s as important as it was taken this far and it was taken seriously.”
A spokesperson for CCOF said in an email that the company was informed by local police on Feb
20 that Ramirez allegedly made threats against Kastel
CCOF placed Ramirez on administrative leave and conducted an internal investigation
which ended in Ramirez’s termination five days later
“CCOF has a zero-tolerance policy regarding violence or threats of violence,” the company said in a statement
“We unequivocally do not condone any threat of violence to any person at any time under any circumstances.”
In a signed letter shared by OrganicEye
saying he did not intend to cause “harm
fear or distress” and stating he acted as an individual
Kastel said he offered to forgo seeking charges against Ramirez in exchange for the apology
But he said his organization is interested in investigating whether criticism or statements made by CCOF leadership may have motivated Ramirez to act
“This is certainly symptomatic of a society that is not being polite to each other,” he said
“There’s some kind of false insulation that people feel exists when they interact online
Many people say and do things that they would never say face to face

Corrigendum: Small steps for mankind: Modeling the emergence of cumulative culture from joint active inference communication
Although the increase in the use of dynamical modeling in the literature on cultural evolution makes current models more mathematically sophisticated
these models have yet to be tested or validated
This paper provides a testable deep active inference formulation of social behavior and accompanying simulations of cumulative culture in two steps: First
we cast cultural transmission as a bi-directional process of communication that induces a generalized synchrony (operationalized as a particular convergence) between the belief states of interlocutors
we cast social or cultural exchange as a process of active inference by equipping agents with the choice of who to engage in communication with
This induces trade-offs between confirmation of current beliefs and exploration of the social environment
We find that cumulative culture emerges from belief updating (i.e.
active inference and learning) in the form of a joint minimization of uncertainty
The emergent cultural equilibria are characterized by a segregation into groups
whose belief systems are actively sustained by selective
The nature of these equilibria depends sensitively on the precision afforded by various probabilistic mappings in each individual's generative model of their encultured niche
Currently these models have only been applied to relatively low level cognitive processes
but the creation of high level cognitive maps at the individual level as well as modeling the emergence of cultural change on the population-wide dynamics represents a promising line of future work
While the comparison of an idea to a (non-mutating) virus has its benefits from a formal perspective
it implies the controversial notion that an idea is simply copied during its transmission through cultural exchange between individuals
This notion is not only intuitively insufficient for a realistic characterization of communication dynamics
but also conflicts with established theoretical models of transmission on these same grounds
conversation partners have to be understood as active participants that co-create these partially shared reference frames in a self-organizing fashion over the course of each interaction
Intersubjective theories of communication aim to account for those underlying dynamics that—slightly paradoxically—both enable and (to some extent) require the co-creation of (partially) shared reference frames amongst interlocutors
traditional formulations have tended to oversimplify communication in terms of back-and-forth exchanges based on (largely) fixed symbolic meaning systems
implicitly presupposing those shared reference frames in an ad-hoc manner
The theory of cumulative culture (Stout and Hecht, 2017; Dunstone and Caldwell, 2018) expands on the notion that progressive alterations of cultural beliefs and practices are intrinsic to all cultural exchanges because they are embodied, expressed, and interpreted differently by each individual participant of the ensemble (Dean et al., 2014)
While efficient cultural exchanges do tend to be grounded in similar physical substrates across and within individuals (e.g.
the high abstraction levels and malleability of these substrates render cultural dynamics in a different class than phenomena that are wholly dependent on consistency across genetic substrates
such as sexual reproduction and disease spread
genetics does play a crucial role in the range of phenomena associated with gene-culture co-evolution
Textual overlap has been minimized and reprinted Figures have been highlighted where relevant
Since cultural transmission only occurs when social behaviors or beliefs are learned
communication only truly implies transmission when what is being communicated has been picked up and solidified in the receiver's cognitive model
We assume this kind of communication in our simulations
which is why under our account communication does imply transmission
Although cultural transmission does not necessarily require verbal communication
we assume this kind of communication in our simulations
When active inference agents engage in the coupled dynamics of communication
generalized synchrony between their internal states emerges from their mutual efforts to minimize uncertainty—as scored mathematically with (variational) free energy
generalized synchrony ensures the greatest mutual predictability error resolves the greatest amount of collective uncertainty
Our model of communication builds on the notion of generalized synchrony to suggest that the emergence of synchrony from the coupled communication of active inference agents may be operationalized as a particular convergence between their respective generative models
when we simulate the belief-updating dynamics of communicating agents
the cultural reproduction of a particular idea takes the form of a learnable convergence between their respective belief states (expressed as generative models) and distinct representations combine into one synchronized
Formally, our model defines perceptual inference in terms of a coupling parameter linking the internal states of interlocutors through dialogue (Figure 1)
Also understood as sensitivity to model evidence (A1)
perceptual inference is a direct and explicit form of coupling that occurs over the span of a single dialogue such that it is hypothesized to modulate agents' convergence of internal belief states during communication
Our model defines two groups of parameters that couple the internal states of agents: Learning and inference
Perceptual learning (A2) is the learning of associations between emotional valence and belief states that guide the long term actions of our agents who hold and express beliefs
accumulating across multiple interactions and used to modify models over extended periods of exchange
sensitivity to model evidence—operates on fast time scales and is direct and explicit to agents during dialogue
we hypothesized that without precise evidence accumulation
agents would be insensitive to evidence regarding the belief state of the other
and their internal states would not converge
Cultural beliefs and practices spread within a society through communication
a process which we have referred to as the local dynamics of cumulative culture
This description is appropriate because the accumulated outcomes of each (local) dyadic interaction collectively determine the degree to which an idea is prevalent in a culture
Moving from local communication dynamics to the prevalence of a communicable idea—in a cumulative culture—is what we will refer to as the global dynamics of cumulative culture
The attunement of interlocutors to each other's generative models on the (local) microscale thus translated over time and with multiple encounters into collective free energy minimization on the (global) macroscale
For a formal (variational free energy) proof of principle
we offer an active inference account of cultural dynamics
A foundational step in this endeavor is the formulation of generative models underlying the decision making of agents that can be deployed in simulations
In our simulations, agents attempt to convince each other of a cultural belief under generative models that operate with local information only. We formulate these generative models as a partially observed Markov decision process (MDP), where beliefs take the form of discrete probability distributions (for technical details on MDPs in active inference, see Hesp et al., 2019)
To simulate active inference under these models
one specifies variables—such as hidden states (x
observable outcomes (o) and one-step action policies (u)—alongside parameters specifying the probabilistic relationships between the variables in question
Agents' recollection of a visit is thus an expression of humans' innate ability to infer each other's expectations, which makes human cognition, sociality, and culture possible at all (Veissière et al., 2020)
having evolved to rely on elaborate and highly coordinated action
have expectations regarding other agents' sharing aspects of their own generative model
and thereby believing that other agents have those expectations as well
These carefully and implicitly coordinated and co-constructed expectations allow agents from a particular culture to learn what to expect from each other and leverage those expectations to act accordingly in their environment
In our model these expectations are manifested as agents' information and preference-seeking
which are biased toward the selection of similar interlocutors to engage with
MDPs allow for the construction of a deep hierarchical model comprising nested levels of complexity. Below we will describe those levels and detail the cognitive processes that take place within each one (Figure 2)

Parameters are listed on the left of the generative model and variables are on the right
For our simulations, six kinds of matrices were parameterized (A, B, C, E, C, and G) using two kinds of concentration parameters (α,ε) for Dirichlet distributions, and temperature and rate parameters for precision terms (indicated with γ; see Figure 3 and Appendix A9)
(A) The A1 matrix specifies an agents' perception of an interlocutors' expressed beliefs
The precision of this likelihood mapping determines the agent's sensitivity to these expressions
(B) The A2 matrix represents what the agent has learned about the mapping between her high and low level beliefs
represent what the agent has learned about how hidden states evolve over time
The precision of B matrices can be understood as encoding the volatility of belief states
(D) The E1 matrix is one of two habitual contributions to action selection
It covers two possible outcomes for expressing beliefs
This contribution is specified on a continuous range between (0,1)
where the extremes correspond to either complete confidence in denying or supporting the claim
(E) The E2 matrix is the second habitual component for action
and it holds 50 possible outcomes for meeting selection (i.e.
the probability for meeting each agent in the population)
(F) The expected free energy of allowable policies (i.e.
expected risk (the KL-divergence from the C matrix and biasing toward confirming one's preferred ideas) and expected ambiguity
which biases toward meeting new agents with unknown beliefs
Note: The purpose of this Figure is to draw the attention of the reader to the general form of the matrices shared across the simulated agents
for any individual agent in the simulated population
each of these objects contains specific numbers
which are initially generated procedurally from various probability distributions (described in the text) and change throughout the simulation as the agents interact in their shared environment
Specific numbers could at best describe only one particular agent at a given instance of time (which does not represent the entire population)
the probability distributions used to generate initial values do not reflect the additional steps required such as
the renormalization procedures involved in applying a softmax operator
it would also occlude the fact that certain entries (e.g.
the expected free energy) will vary over time during a simulation
belief updating depends not only on their adherence to each other's claims but also a certain (varying) degree of commitment to their own beliefs
The balance is determined by each agents' sensitivity to sensory evidence; i.e.
Technically, we can describe belief updating in terms of the generative model in Figure 3 as follows:
• Initial higher-level core support for the idea at the beginning of the simulation (T = 1):
• Evolving higher-level beliefs after each meeting (T > 1)
• Initializing lower-level beliefs about the claims of others
based on higher-level (cross-meeting) beliefs:
• Updating beliefs about the other agent's belief based on their claims (Appendix A7)
• Updating of core belief based on claims of self and another agent after each meeting (detailed descriptions of the computations involved in this belief updating can be found in the Appendix):
The initial mapping therefore involves minimal precision for the expected EV for the alternative belief since agents are first introduced to this belief (and associated EV) during the simulations
the initial likelihood mapping between states is updated throughout our simulation via a crucial concentration parameter (α) which will be elaborated on under level 4
The inferred EV state is then used to generate an action precision (γ) such that positive EV generates high confidence in action selection (u1) and negative EV generates low confidence
Higher confidence values produce higher precision on the expected free energy (G) for one's belief claim expressed in the current conversation
EV states are generated from core belief states
Confidence of belief expression is generated using a Gamma distribution
where the rate parameter βexpr is the Bayesian model average of β(+
−) values associated with high and low satisfaction:
The expression of beliefs is guided by current core beliefs (scaled with satisfaction-dependent γexpr) and by habitual belief expression Eexpr (scaled with a fixed parameter γE,expr):
The intrinsically stochastic and itinerant nature of the generative process of communication is modeled by using a two-dimensional Dirichlet distribution to generate observed expressions on the range (0,1)
where each agent's belief expression prior P(uexpr|γexpr) is used to specify their concentration parameters (multiplied by 12 to reduce variance):
A simplified example of exploitation- and exploration-driven strategies for meeting selection
This Figure illustrates the behavioral differences between the extreme cases of being fully driven by exploitation (Left) or exploration (Right)
Each cell on the grid corresponds to a potential interlocutor for these agents
who make decisions in three consecutive time steps (t = 1
3) and have previously engaged with three other interlocutors (marked with blue rectangles)
where we use the shorthand klC to indicate the pragmatic component of the expected free energy Gpragmatic,visit = oexpr,visit · (ln oexpr,visit − Cidea)
which corresponds to the KL divergence between expectations about the interlocutor at that location (as informed by previous visits) and the preferred ideas of our agents
such that lower values correspond to a better match
The exploitation-driven agent (Left) simply revisits three times a known interlocutor with the lowest KLC
the exploration-driven agent (Right) prefers novel visits and switches to an unknown agent every time step
agents will dynamically balance these two strategies as their preferences themselves evolve over time
action selection was formalized as follows:
Gvisit represents the expected free energy:
Expectations about the support for an idea expressed by each potential agent one could visit:
Individual preferences about the support for the idea:
expectations about a potential reduction in ambiguity about the support for an idea by a particular agent reflects one's recollection about their most recent visit to this other agent
Hj = 0 if an agent can remember a recent visit (i.e.
maximization of epistemic value helps individuals to better predict the consequences of their actions (e.g.
when they decide which agent to meet) as they reduce uncertainty about hidden states of their environment
in this case it refers to the ideas supported by other agents)
Because of our method of procedural generation of various (hyper)parameters from various probability distributions (described in more detail in the Appendix)
and affective tendencies emerged in our simulations due to the large variety of possible combinations
In principle one could obtain any range of behaviors from this method of procedural generation based on a set of probability distributions for all these hyperparameters
which could hence be fitted to population data
A full-blown analysis of all the emergent variability in the simulated populations is beyond the scope of the current paper
For the sake of our demonstration, a clear distinction between agents with high and low confirmation bias was introduced in our simulations by drawing individualized hyperparameters from two distinct sets of Dirichlet distributions (illustrated in Figure 5; described in the Appendix) to obtain each agent's likelihood mapping from higher-level core beliefs to lower-level preferences concerning observed expressions
The resulting distinct populations could have emerged from
cultural segregation where different cultural subgroups have developed different priorities in guiding social interactions—in this case guided more or less strongly by confirmation of core beliefs
Two sets of expectation values of the Dirichlet distributions used to generate top-down likelihood mappings AC(2)
from core beliefs about ideas X(2) to preferences concerning expressed ideas Cidea
representing the two distinct populations for which parameters were initialized with different degrees of confirmation bias
Weak confirmation bias (Left) corresponded to mild preferences for observed expressions to confirm core beliefs
while strong confirmation bias (Right) corresponded to a strong preference for observed expressions to confirm core beliefs (essentially a one-to-one mapping)
Novelty-seeking tendencies were not explicitly coded and simply emerged from the parameters that regulate the relative impact of epistemic vs. pragmatic value in the expected free energy, although it should be clear that high confirmation bias tends to suppress novelty-seeking. In Figure 6
the distinction between “strict conservatives,” “centrists,” and “skeptics” was used to qualitatively describe the emergent continuous spectrum purely for communicative purposes and should not be taken as a definite discretization
A depiction of the community square with its initial opinion distribution: One idea (red) was supported by almost all agents
with some variation due to individualized model parameters
roughly dividing into “strict conservatives,” “centrists,” and a few “skeptics.” At first
the alternative idea (blue) is supported by only one
This kind of learning is important because it provides our agents with certainty
regarding the emotional value they can expect from holding the alternative belief to the status quo
which has low precision at the beginning of the simulation (before the population is introduced to an agent proclaiming this belief)
The learning of associations between belief and emotional valence states may be understood as a form of implicit coupling between agents (Figure 1)
in that it represents an indirect and secondary influence of one agent's internal state on another
sensitivity to each others' mental states is made possible only through inferences about the others' emotional state (in the absence of any overt or observable evidence for that emotional state)
learning occurs at slow time scales as mutual minimization of prediction error brings about a convergence in the parameters of hierarchical models that generate mutually sympathetic (or possibly empathetic) predictions
Parameter learning accumulates across multiple interactions
modifying generative models over a long period of time as opposed to being immediately expressed in agents' behavior
This is why perceptual learning does not bring about an immediate convergence or synchrony between interlocutors' internal states
but is only expressed in agents' adapted behavior over time
Individuals vary in the degree to which they are sensitive to the information gained by learning associations between belief states and their potential emotional outcomes
This variation is represented in each agent's categorical probability distribution A2 that is updated throughout the simulation via a concentration parameter (α) as they accumulate information with every agent they meet
Updates to the A2-concentration parameters model the way in which agents' associations between belief and emotional states are based on implicit observations of others' emotional states
The prior for this likelihood mapping is specified in terms of a Dirichlet distribution:
The associated approximate posterior accumulates the precision-weighted counts of correspondences between observed expressions and satisfaction levels:
A diagram illustrating the steps of the generative model
(Left) Lower level Step 1: Interlocutor selection
each agent selects one interaction partner (selecting themselves means staying home)
Agents cannot see each other's “opinion” before conversing
Meeting selection was conditioned on: (1) Habitual visitation drives
conditioned on: (2a) Expected (mis)match between expressed opinions (pragmatic value) and (2a) expected reduction in uncertainty about opinions of other agents
depending on one's memory of recent visits (epistemic value)
(Right) Lower level Step 2: Conversation with a selected agent
Each meeting consisted in exchanges of expressed support for an idea [in the range (0,1)] and affective cues [negative-positive
Expressed support was conditioned on: (1) Expression habits formed during past conversations
(2) one's current support for the idea
Expressed affective cues were conditioned on one's current valence state
Affect played a role during Steps 1 and 2: Relative reliance on habitual tendencies vs
deliberation (expected free energy G) was regulated via action model precision
The latter was conditioned on one's current valence state
which was conditioned on one's current support of an idea
depending on previously learned associations between expressed ideas and concurrent affective cues (from oneself and others)
• Expected support for idea (from self and others)
• Expected claim expressions (from self and others)
• Memory of most recent visit of other agents
• Current selection of an agent to visit
• Expressed opinions (when visiting and when visited)
• Expressed affective cues (when visiting and when visited)
every agent maintains (implicit) beliefs about the following:
• Support for idea from self and others
• Habits of expressed support (self)
• Recency of visits to and from others
• Visitation habits of self (dirichlet counts)
• Affect-idea associations (dirichlet counts)
Active inference allows us to formulate a normative and explainable account of cultural information spread through communication by casting cultural transmission as a bi-directional communicative process that entails a particular convergence between distinct conveyors and conveners of cultural information
We provide a proof of concept for this formalization of communication dynamics by simulating a dialogue between active inference agents holding distinct beliefs and trying to convince each other of their own beliefs
Modeling the global dynamics of a cumulative culture (i.e.
the accumulation of cultural information over a manifold of transmissions)
was modeled such that—at each time point all 50 agents engaged in dialogue at least once (by selecting a conversation partner)
In nature, generalized synchrony emerges from sparse coupling between the internal states of dissipative chaotic systems (Pikovsky et al., 2003). In our model, generalized synchrony within a social system is operationalized as a convergence between belief states held by interlocutors (Figure 1)
generalized synchrony between mutually inferring agents is understood as signaling a form of cultural reproduction of beliefs
a mechanism by which previously distinct internal states merge and combine into one
This convergence is made possible through a particular coupling between the internal states of cultural entities
under which generalized synchrony is an emergent phenomenon
We hypothesized that without active perception and mutual model updating
since interlocutors' inner states would be inaccessible to each other
agents' ability to actively infer hidden states in the world and update their own model according to the sensory evidence they receive is the foundation for achieving generalized synchrony in a social system
Our results indicate that agents' ability to listen and attune to the claims of their partner is indeed limited to the extent that they are sensitive to sensory evidence from their encultured environment (Figure 8)
While this internal state is defined as a binary variable
an agent's beliefs are given by a categorical probability distribution that can take on any real number in the range (0,1)
This figure shows the belief states (vertical axes) of two agents (represented in blue and pink) as they engage in dialogue across 18 time steps (horizontal axis)
When the likelihood precision is low for both agents (Left) their internal states are very weakly coupled
such that each agent sticks to their own belief and does not attune to the claims of the other
when both agents have high precisions (Right) their engagement in mutual attunement is facilitated and their beliefs converge onto one shared belief
which is then installed in both of their generative models as a shared narrative
To understand the implications of these findings, it is important to shed light on the way they tie in to previous work on active inference communication. In Friston and Frith (2015) provided evidence for the notion that generalized synchrony becomes altogether unattainable when agents do not possess sufficiently similar generative models
Our results go beyond this and provide evidence for the idea that only when generalized synchrony is attainable (i.e.
when interlocutors possess sufficiently similar generative models)
communication underlies a convergence between agents' belief states
Our simulations should therefore be understood as taking generalized synchrony for granted while providing evidence for the premise that the level to which agents' beliefs converge (i.e.
the level of synchrony between their internal states) is modulated by their sensitivity to model evidence (A1)
Our simulations of a cumulative culture should be understood as modeling the dynamics of a culture that is the sum (or accumulation) of modifications to cultural beliefs and practices over time (Figure 9)
While the local dyadic dynamics simulated in the previous section illustrate convergence to shared belief states held by individual agents
our global simulations leverage this synchronization to evince emergent dynamics within the population
We now review the key (predicted and) emergent phenomena we observed under this model of cumulative culture:
Figure 9. The emergence of cumulative culture. This Figure and its caption were adapted from an open-source preprint of a conference paper, with permission of the authors (Figure 3 of Kastel and Hesp, 2021)
These plots depict the evolution of population-averaged support (black line) with regards to the idea that represents the initial status quo (top indicates 100% support
bottom indicates 0% support) over time (horizontal axes) along with individual core beliefs (shown in the underlying scatter plot
for which only the relative size of the subgroup with high confirmation bias was modulated [(A): 5%
The underlying scatter plots indicate the core beliefs of individual agents by means of their vertical location as well
with a color scale for additional clarity (red indicating maximal support for the status quo
(A) Simulation of a Cumulative Culture: In this reference simulation
half of all agents are parameterized with high confirmation bias
When a divergent belief state (blue) is introduced to the status quo population (red) at the first time step
it spreads through it via agents in dialogue that cumulatively change the belief structure within the population
the introduction of a divergent belief seems to split the population into two subgroups: those supporting the new idea
and those adhering to the previous status quo
This effect is modulated by agents' individual strategies for choosing which interlocutors to engage with (s3)
(B) High levels of novelty seeking in the population: When only 15% of agents are parameterized with high confirmation bias
the population exhibits high levels of novelty seeking and ends up being divided in favor of the divergent belief state
with more agents eventually holding this belief than the status quo
(C) High levels of confirmation bias in the population
When 85% of agents are parameterized with high confirmation bias
the population is divided in favor of the status quo belief
with more agents holding to this belief than the new and divergent belief
When a divergent (non status quo) belief state propagates within our synthetic population
it brings about segregation into sub-groups
this is represented as a visible separation between two groups of agents: those that hold a belief that approximates the status quo (presented in red)
and those that approximate the alternative
the majority of agents remains convinced of the previous status quo
These results indicate that confirmation bias suppresses tendencies of the population as a whole toward the adoption of an idea that diverges from the status quo
When the confirmation-driven fraction of the population is relatively low (15%)
we naturally observe more novelty-seeking behaviors
indicating agents are more “open-minded” and willing to meet with agents of unknown beliefs
They are intrinsically encouraged by their own curiosity to expose themselves to novel expressions
Once such agents become convinced by such interactions
they can start to popularize it for the rest of the population
made up of a majority of agents driven by confirmation bias
they do not engage as much with the alternative belief and popularization is precluded
One explanation for this phenomenon is that innovators and early adopters communicate innovations and their relative advantages to other segments of the population
we provide an active inference framework for the emergence of a cumulative culture from joint communication dynamics
The principal achievement of this framework is that it offers an overarching
quantitative and multiscale account against which multiple hypotheses from different domains of the social sciences may be universally tested
This accomplishment has the potentiality to bring the replication crisis faced by the psychological and social sciences in the past decade
standardized model of cultural evolution can evoke such an outcome as personal intuitions and culturally biased folk theories that currently make results difficult or impossible to reproduce
will become anchored to an objective and universally agreed upon verifiable account
Our simulations depict cultural dynamics that arise from one another to form nested levels of hierarchical organization
quintessential to complex dynamical systems
This novel way of modeling cultural dynamics across layers of organization accord nicely with new approaches to artificial intelligence that originate from the notion that intelligence emerges as much from cells and societies as it does from individuals
The emerging field of biologically inspired artificial intelligence involves computational approaches that model biological systems on various layers of organization
Such artificial intelligence systems include: cellular systems; neural systems; immune systems; bio-mimetic
epi-genetic and evolutionary robots as well as collective systems
In this section we will discuss the specific implications of our multilevel cultural simulations on the field of biologically inspired artificial intelligence
These findings suggest that humans might owe their remarkable intelligence to their unique ability to coordinate their behavior through joint communication and other (non verbal) cultural exchanges
communication and coordination- are a crucial component of human intelligence
This makes a strong case for the use of communication models as inspiration for the development of socially intelligent artificial agents
equipping artificial agents with the ability to accurately coordinate and communicate with other agents in their environment may well be a crucial missing piece in the modeling of advanced- human level- cognitive abilities
By modeling the underlying dynamics of social communication and coordination as we have in this paper
we bring to light an otherwise unexplored topic
which may be one of the most promising directions for achieving human level machine intelligence
is evident in nature and has become an integral part in the field of artificial intelligence as more and more high complexity problems require bio-inspired solutions that are achievable within a reasonable period of time
To the extent that the cumulative and collective nature of culture provides an accurate account of intelligence
investigating the underlying mechanisms of intelligence may be informed by the investigation of complex social-cultural systems
providing a quantitative and measurable account of the way a “collective brain” emerges from simple
becomes invaluable in the pursuit of machine intelligence
A natural speculation may be that robots have better skills of communication and inter-robot social inference and expression than digital avatars
since they can use their bodies for behavioral expression and coordination with other robots
we argue that despite lacking a physical body
active inference avatars are embodied in that the computational formalism that is applied to them (namely
what this means is that active inference agents in our simulations adhere to three formal conditions for having embodied cognition:
1. They have a perceptual system which allows them to gather culturally relevant information from their surroundings. This is evident in the first layer (“perception”) of the hierarchical structure of the generative model of the agents (Figure 2)
2. They have a motor system that allows them to communicate their internal states to their social environment. This is evident in the third layer (“action”) of the hierarchical structure of the generative model of the agents (Figure 2)
3. They are situated in their environment such that they are able to manipulate their dynamic surroundings through their actions. This is evident in agents' ability to listen and attune to each others' belief expression in a way that allows for a coupling of their internal states and the emergence of generalized synchrony between them (Figure 8)
The fact that agents under the active inference formulation conform to these three conditions is non trivial
and it points to the fact that these agents could not be simply replaced by any hypothetical- non embodied- simulated intelligent being
our simulations would not make sense unless applied to a population that adheres to the certain criteria aforementioned
We could only apply our simulations to agents that adhere to all these conditions (i.e.
our agents may not be physically embodied robots
but we argue that- by definition- as active inference agents capable of perceptions and actions in a situated environment
Had we put this software into social robots that had the hardware equivalent of “ears” and “mouths,” we would be able to produce embodied robots in a way that would improve their social interactions
we argue here that embodiment must be present in both the software and the hardware for social interactions of agents to be enhanced by it
and that the active inference formalism implies embodiment for the former
Although this paper provides important insights into the underlying dynamics of social-cultural systems
it entails certain limitations that will now be outlined and may be addressed in future research
while we provide a formulation of the way modifications to cultural information occur during communication (i.e.
the transmission of social information) and we have simulated the emergence of cumulative culture from these dynamics (i.e.
we have not provided an account of the way novel social information is introduced into a population to begin with
We have assumed that belief states are gradually modified with every cultural exchange
such that the outcome of this exchange may be considered novel by virtue of it being a unique recombination of existing beliefs and practices
Future research may focus on asking important questions like: Why are we inclined to say that innovation is a unique event that does not occur with every cultural transmission
how can we define and even model the difference between a slight modification to a cultural trait and innovation
The importance of identifying exactly what constitutes innovation and how to model its emergence is critical for an accurate understanding of socio-cultural dynamics because it would bring the circular dynamics of a complex culture to a required close (Figure 10)
not only would cumulative culture naturally emerge from a complex network of agents engaged in joint communication (as shown in this proposal)
but innovation would emerge from cumulative culture and underlie communication in a repeating
recursive loop that is the hallmark of complex dynamical systems
The circular dynamics of cultural evolution
the authors aim to expand on these notions by enriching the simulated environment with actual practical constraints
will specifically benefit from the grounding of these simulated cultural exchanges in a more elaborate virtual environment combined with agents that have actual bodily and social needs such that subjective fitness estimates (based on action-model precision) come to confer some practical relevance (as described in the preceding paragraph)
In this paper, we employed a Bayesian framework—known as active inference—to formally account for the dynamics underlying (local) communication and (global) cumulative culture dynamics, thus contributing to the ever-growing body of research on multi-agent Bayesian models (e.g., Gunji et al., 2018) and collective active inference (e.g., Friedman et al., 2021; Heins et al., 2022) Under our account
the social “transmission” of cultural information has been cast as a fundamentally bidirectional process of communication
which has been shown in the previous active inference literature to induce a generalized synchrony between the internal (belief) states of agents holding sufficiently similar generative models
we operationalized generalized synchrony as a particular convergence between the internal states of interlocutors
and show that it depends sensitively on the precision of observation or likelihood mappings in a generative model of communicative exchange
When we simulate a population of agents that simultaneously engage in communication over time
cumulative culture emerges as the collective behavior brought about by local belief updating (active inference and learning in a dyadic setting)
Our simulations show that when a divergent belief is introduced to the status quo
it spreads within the population and brings about a collective behavior characterized by a certain degree of segregation between different belief groups
The level to which the status quo population defects to the divergent belief is mediated by local psychological biases for confirmation bias (as directly manipulated) and novelty seeking (as emergent from procedural generation of parameters)
voting) equilibria are minimizers of collective or joint free energy that emerge from the imperative to minimize uncertainty and surprise in dyadic exchanges

Editors’ note: America has published several essays on the one-year anniversary of the Oct. 7 attack on Israel and on the war in Gaza. Read other views on the conflict between Israel and Palestine here
I was about to enter my synagogue to celebrate the holiday of Simchat Torah (literally
the “joy of Torah”) when I was approached by a congregant asking me about what was happening in Israel
I assumed that she was talking about the issue of judicial reform
but what she told me shocked me to my core
There had been an invasion with thousands of terrorists managing to get into the country and do the worst horrors imaginable
I was in shock and have been reeling from it ever since
Considering the prejudice and persecution that the Jewish people have endured throughout our history
That is why the re-establishment of our homeland
2,000 years after forced exile by the Romans represented not just our pride but our very survival
We now had a place to go if (or when) a bigoted population scapegoated us for their failures
But it is the gaslighting and abuse coming at the global Jewish community since Oct
Despite many of the terrorists proudly livestreaming their atrocities we have been confronted with denials
justifications and even glorifications of these attacks
At first the rationalizations and justifications for Hamas were from the predictable quarters
but these quickly spread to college students
This narrative characterized Israel as the epitome of colonialism
Old antisemitic tropes were reclaimed from the dustbin of history and brought back to life
The chants “From the river to the sea, Palestine will be free” became more frequent
and we were supposed to pretend that this wasn’t a genocidal cry to rid the Holy Land of Jews
That “globalize the Intifada” and “by any means necessary” weren’t calls to violence against Jews everywhere
Criticism of particular Israeli politicians and policies is appropriate and a critical part of democracy
I am not equating such criticism with antisemitism
It is the criticism of Israel’s existence as a Jewish state
while not having a problem with countries that have other official religions like Islam
It is calling Israelis colonizers while sitting on Native American land that is hypocritical
It is comparing Israel to apartheid South Africa that is offensive
which started the war and put Israel into an impossible situation
The statement stresses that “there are other choices that could be made” in the Middle East
but without offering another choice that includes keeping Israel safe
General Assembly adopted 15 resolutions critical of Israel in 2023; it adopted only seven such resolutions for all the other nations in the world combined
Hamas can claim that Israel is attacking civilians and committing war crimes
As I was preparing my sermons for the Jewish high holy days
I was plagued by the question of how and why many good people seem to have jumped on the “free Palestine” bandwagon and bought into some of the worst accusations against us
The answer that came to me was extreme empathy
associated with “the resistance,” has become fashionable
and that hating Zionists is seen as a kind of antiracism
I encouraged my congregation to learn about how empathy can be a tremendously powerful tool for good
That harm happens when people get too caught up in the emotionality of empathy and suspend using their objective minds
I encouraged them to consider the value of what psychologist Paul Bloom calls “rational compassion” instead of only empathy
I also reminded them that no matter how much we are dehumanized by our detractors
it is against our values to dehumanize others
We should be careful not to let our empathy for our brothers and sisters in Israel lead us to condemning all Palestinians and their supporters
we all are able to see all people as God’s children who deserve to live in peace and freedom
As stated by the prophet Isaiah 2:4: “Nation shall not lift up sword against nation.”

I needed to catch my flight home and knew this would be the last time I ever saw my father
I asked if he wanted the door open or closed
Dad and I were closing out our time together
The trouble had begun a year earlier when my sister called to say that Dad was hospitalized with heart failure
The diagnosis seemed to come out of the blue
His kidney disease had caused heart failure
Not that I believed my 92-year-old father was indestructible
and Dad kept himself in good shape both physically and mentally
Dad’s work and family were everything
He was itching to get back home to Milford to finish it
I first saw the oil painting in October of 2022
when I flew up from Baltimore to see him after he became ill
What struck me was the photo he was working from
It was me as a young boy from the shoulders up
standing in our rickety barn in Clove Valley
The same barn where Dad would later paint his acclaimed Jaws and The Empire Strikes Back movie posters from his upstairs studio
There was something about my facial expression
I could swear that child was unusually meditative for someone that young
or had Dad caught something in me I wasn’t aware of
It was both off-putting and remarkable to see this image after all these years
he could not get it to translate the way he wanted on canvas
Four years earlier, I had written a magazine retrospective of my father’s career, “The Art of Roger Kastel.” I’d stepped into his studio with its bright fluorescent lighting
and paintbrushes of every size imaginable standing bristles-up in an old coffee can
in between extended hospital stays and never-ending medical examinations
on the rare days he could muster the strength
he would valiantly descend the stairs to his studio
and pick up his brush to give it another try
that’s what art is — man’s passion laid out on canvas
My portrait may never have gotten done to the artist’s satisfaction
along with the man whose lifelong journey was one of joy
and kindness — a trip he generously took with us

The creator of one of the most iconic posters in movie history has died
Roger Kastel was as an acclaimed illustrator and artist whose work appeared in many forms — but his single most famous piece is the one that became the poster for Steven Spielberg’s Jaws
with its bullet-shaped Great White shark racing out of the depths at a beautiful swimmer at the ocean’s surface
Kastel’s Jaws poster was originally made for the paperback edition of Peter Benchley’s novel
The publisher decided the book’s hardcover art — a shark set against a black void — would not work for the new edition
and commissioned Kastel to create a new painting
In the Jaws making-of documentary The Shark Is Still Working
Kastel details how he created this unforgettable image
“I did a very rough sketch,” he said
“and [the publisher] said ‘That’s great
Kastel went to the Museum of Natural History to photograph some of their sharks
“I said ‘Do you have a shark exhibit in the building?’ [The employee] said ‘Yes we do,’ but they were all down
I knew what position I wanted the shark in and there was this great white that they had laying on a easel; I guess they were dusting it
And that’s what I worked from.”
Kastel asked a model he hired to pose for another piece in Good Housekeeping to spend an extra 30 minutes “swimming” on a stool in his New York studio as the reference for that component of the piece
the image became synonymous with Benchley’s novel
When the film’s producers asked to use it as their movie poster
thinking it would be great publicity for the book — which it was

According to his official website, Kastel was a native of White Plains, New York who studied at the Arts Students League in New York City, and became a freelance artist after a stint in the Navy during the Korean War. He produced over 1,000 illustrations for various publishers and novels; after Jaws he made posters for other famous movies — including the beautiful artwork for The Empire Strikes Back.
Legendary movie poster artist Drew Struzan paid tribute to Kastel on Twitter
writing “We lost another creative brother ..
Roger Kastel who gave us the iconic Jaws poster among other wonderful pieces of art.”
Kastel also illustrated the ‘Empire Strikes Back’ poster.\nRead More

— One by one the cows were filed into the arena in front of a few hundred men
women and children that filled an outdoor tent on the Kastel Show Cattle farm for the 15th annual Kastel Show Cattle & Friends sale
The sale is one of the largest in the area with 113 lots being auctioned off on the muddy Sunday afternoon
This is where the 4-H and Future Farmers of America participants who raise and show cattle at state and county fairs
bred cows and embryos from over 113 calves auctioned
The calves auctioned were either owned by Josh & Michelle or consignments
consigning or selling means that they have either bought or bred cows from the Kastels
The buyers in the tent were completely focused on the animal being led by the ring man inside the arena while cattle auctioneer
You have to have someone experienced in cattle (and) he’s one of the best,” Michelle Kastel said
“When we decided to do this we wanted to make it about the families and we wanted to bring the best of the best in to take care of it … .”
each new animal would get a thorough description by Josh Kastel prior to it being auctioned
“This is the first time we’ve been here,” Bret Cleveland
“We bred one of Josh’s bulls and he allowed us to bring it up here to sell it.”
Cleveland’s heifer sold for $3,200 that day
“I’ve never been to a cattle sale before so this is my first.”
the event hosted between 400 and 650 people over two nights
Saturday night was a customer appreciation day
viewing of the calves and a performance by a live band
despite the severe thunderstorms in the area
Even though all the rain and mud and everything else
“(The storms) cleared up so we got a generator with a light tower and we put those calves underneath that light and people were out there with umbrellas looking at the calves in the mud — which is a lot of die-hards
bred cows (cows that are already pregnant) and embryos are bought by farmers to breed for their own farms
The visitors to the farm were mostly from Michigan
Ohio and Indiana but buyers from states as far as Oklahoma
West Virginia and Texas were also present to name a few
it’s about the kids,” Michelle Kastel said
“We love working with the kids and their family and the kids that show our cattle end up being like our family.”
“It’s one of the biggest sales in the country and that’s the honest truth,” Andy Chamberlain
selling and purchasing cattle as well as helping the event by selling the Kastels hay and straw from his farm
“Josh has helped us out so we love coming to this and seeing cattle
And I showed cattle growing up too,” Mackenzie Chamberlain
“He puts in the hours from morning to night with everyone that he sells them to
So when you buy an animal here (he’ll) stick with you till the end or when you breed it so he keeps people coming back.”
When Josh Kastel returned from veterinary school in 2000
The Kastels realized that Michigan was lacking a good cattle auction and Josh said that he went around to his breeder friends in the area pitching the idea
I’m thinking of putting this sale together
would you be interested in being part of it?’ Because obviously
at the time I didn’t have enough calves,” Josh Kastel said
it will never fly in the state of Michigan because we’re not out west… .”
“So that kind of made me strive to make this thing the best it could be … and give a place for kids to come and get a good quality calf for a reasonable price.”
Michelle Kastel said that the auction first began as a small board auction
and transitioned to a live auction seven years ago
Both Josh and Michelle Kastel showed cattle when they participated in 4-H
a program to teach children agricultural skills such as raising livestock and the responsibility and hard work that comes with it
Josh Kastel talked about one girl who was brought to tears from happiness Sunday after her family won the auction for the steer she wanted
it’s kind of like handing down the torch,” Josh Kastel said
“‘We show calves and our kids are going to show calves and their kids are going to show calves.’ That’s what it all boils down to.”
While still a student Roger had his first paperback book cover published in the 1960’s by Pocket Books (Simon Schuster)
Roger estimates that he has done over a 1,000 illustrations for various publishers
a painting of Roger’s won first prize from the National Fire Underwriters
This painting was made into a fire safety poster that was used for many years and had high visibility
By the 1970’s Roger Kastel hit full stride as an artist
becoming one of the most well respected illustrators in the business
working for every major publishing house in New York
If his work was not yet recognized globally that was about to change in a big way when he accepted the challenge of illustrating the paperback cover of Peter Benchley’s bestselling classic JAWS for Bantam Books
purchased the right to use this image as the poster for the movie
This was the first time that a poster image became a merchandising product in itself
Forty years later Roger’s illustration is still as instantly recognized throughout the world as when it first exploded onto the scene
Roger’s reputation as a top flight illustrator now made its way to Hollywood
and he was asked to paint the movie poster for George Lucas’ highly anticipated sequel to Star Wars: The Empire Strikes Back
This poster also became an instant classic and is considered one of the most influential movie posters every produced

Charlotte Jorst and Kastel’s Nintendo
Although Jorst admitted she was a little rusty last week getting started again
you certainly couldn’t tell as she won the Grand Prix yesterday and topped the Grand Prix Special today with a 68.80%
“I still didn’t achieve my goal of no mistakes
but Nintendo as usual was doing his very best
and I can’t believe what a great horse he has been to me
I’m just so incredibly grateful for owning him.”

There’s lemons and beautiful things all over
It’s a really great place for a horse to relax
I think they need to clear their minds sometimes

Winning Ride: Charlotte Jorst and Kastel’s Nintendo“Nintendo was as usual doing his very best and being out there for me
It’s going on 5 years now and I cant belive what a great horse he is and I’m so incredibly greatful for owning him.”
Charlotte Jorst and Kastel’s Nintendo hold their lead in the USEF Grand Prix Dressage National Championship
scoring a 68.80% to win the Grand Prix Special at #FestivalofChampions
Posted by USA Dressage on Friday
“It’s been a fantastic summer for all of us
and the horses are certainly fresh and ready,” she continued
“I was a little exhausted when I started out with two lessons on Saturday
I think sometimes you have to think and wake up and say ‘Do I really love doing it like this or do I want to restart everything?’ So that’s what I’m doing.”
Jorst is excited to ride a new freestyle on Sunday
although she’s never ridden to the music and was only able to listen to it for the first time today
“I’m really excited about the music and how it all pans out on Sunday,” she said
Jennifer Schrader-Williams and Millione finished second in the Grand Prix Special on 68.17%
Nick Wagman and Don John finished third in the Grand Prix Special with a 67.47%
Mette Rosencrantz and Marron were fourth in the Grand Prix Special with 66.97%

Learn how to describe the purpose of the image (opens in a new tab)
Leave empty if the image is purely decorative
celebrated for his iconic poster design for the classic Steven Spielberg film Jaws
leaving behind a legacy that transcends the world of cinema.
featuring a mako shark - and not a great white shark - rising from the depths towards a lone swimmer
became instantly recognisable and synonymous with the suspense and terror of the film
Kastel didn't head to the ocean for inspiration
instead he paid a visit to the American Museum of Natural History
he took a some photos of stuffed mako sharks waiting to be cleaned
but in the finished artwork the shark is positioned as if it is rising through the water
Not that the now iconic image started life as the film's poster
Roger's work was not yet recognised globally
but that was about to change in a big way when he accepted the challenge of illustrating the paperback cover of Peter Benchley’s bestselling classic JAWS for Bantam Books. Universal Studios
said: "Kastel's ability to distill the essence of a movie into a single image was unparalleled
The JAWS poster captured the primal fear associated with the unknown lurking beneath the ocean's surface
setting a new standard for movie marketing
The image not only contributed to the film's success but also solidified Kastel's reputation as a master of visual storytelling."
And that original JAWS poster artwork that Kastel created
Kastel's other iconic contribution to the world of film posters and popular cinema was that for the sequel to Star Wars
creating the classic Gone With The Wind-style poster.
As news of Kastel's passing reverberates through the creative community
film fans and JAWS fans at the loss of this key JAWS creative
While Roger Kastel may no longer be with us
his artistic legacy lives on through the timeless images he created
The JAWS poster remains a testament to his talent and the power of visual storytelling.
As the world mourns the loss of a visionary artist
his work continues to inspire (and thrill and frighten) generations
ensuring that Roger Kastel's contributions to the art of cinema and beyond will be remembered for years to come

Lilli Kastel of Deerfield didn’t let the coronavirus pandemic ruin her chance of winning the hog showmanship title in 4-H for the second straight year
The 15-year-old daughter of Brent and Vicki Kastel was up to the challenge and was named the top overall showman in the swine division of the first 4-H virtual learning showcase and auction being held this year in place of the Monroe County Fair
She defended her title from 2019 that she won in person at last year’s fair
“It was not as fun as last year,” the sophomore at Blissfield High School said Tuesday about the virtual competition in 2020 that was judged by someone online
We got some feedback online that was helpful
I learned that even if times are difficult (like this year)
Griffin Linn was the reserve champion in showmanship
To help boost her confidence and hone her showing skills
Lilli and her family traveled to jackpot shows in Michigan and Indiana before the showcase to gain more experience showing livestock
She generally took about a half-dozen pigs with her
She had a barrow she showed last winter that brought her lots of success
He was champion overall at shows in Ohio and Michigan earned Top 5 overall at six other shows
She also showed pigs at virtual shows held nationally before the showcase
One of her gilts took eighth overall in the United States and she placed eighth nationally in showmanship
but entered only two of them – both barrows -- in the market division of the showcase
She sent in photos of her 280-pound barrow called “Bucket Head Fred” that she showed in showmanship
The barrow was purchased from breeder Jeff Winter of Dundee
“I spend a lot of time with them and bond with them,” she said
“Some are quite different from” other hogs she has raised in the past
a senior at Blissfield HS – also showed pigs in the showcase
She also showed a Californian rabbit in the market division of small animas at the showcase
She will sell both pigs and her rabbit in the online auction being held this week
Lilli is hoping next year the fair will return and 4-H can “go back to normal and we can show live in person

Magnet fishing is a craze attracting fishers from all walks of life
I’m not referring to fishing for lost refrigerator magnets from underneath your fridge
though that might be the next sport to give pickleball a bit of competition
I got hooked on magnet fishing about a year ago
this activity has little to do with fish and all to do with fishing
Magnet fishing is the act of casting a large magnet on a rope into a body of water to retrieve magnetic treasures
but realistically one usually reels in unique garbage
Over the past year that I've been magnet fishing
I have caught large rusty nails 4 or 5 inches long from wooden docks that are no longer in existence
I’ve hooked square nails and flat head screws
both of those are fun to try to estimate their age by looking up their likeness online
I’ve landed enough fishing paraphernalia to fill a tackle box; some of which is usable daredevils and spinner baits
Some of these were attached to yards and yards of fishing line and each of which I’m sure has an accompanying story of the one that got away
you may also want to check out the web version of this story
as it includes photos of my magnet fishing finds
the license plate was found underground with a metal detector and unearthed with a shovel
Perhaps metal detecting will be my next Tri States Public Radio commentary
And you can be the judge of which of these finds is worthy of the title “catch of the year.” My vote is for the 17 lbs
red boat anchor that was so slimy and gunk ridden that it took two magnets to haul in
Now that I’ve been magnet fishing for some time
I have a bucket list of sorts of things I’d like to catch one day
preferably ones that were just lost where the owner is still in the vicinity
I feel like a cast iron skillet would be a fun one to try to reel in
catching a fishing pole and reel would be meta
and I’d love to go magnet fishing in a country where the coin currency is magnetic
If you’re feeling that magnet fishing is a hobby you’d like to try
let me share some tips I’ve learned to get you started off on the right … magnetic pole
and the benefit of this is that the rope comes with a carabiner to allow you to quickly switch between using a magnet and a grappling hook
which is another useful tool for helping to hall in objects that may not be fully magnetic
I did magnet fish in Canada this past summer
nearly landing a shopping cart on the Canadian side of the Detroit River
What held me back was not the need for a fishing license or that I had reached my daily limit of shopping carts
It was the fact that this was a blue plastic shopping cart and I could only get my magnet on the wheels or the handle bar
I did not own a grappling hook or second magnet and rope
either of which would have helped in this endeavor
I don’t know what I would have done with a muddy
corroded shopping cart if I had landed that beauty
I find it useful to keep containers for recyclables and trash
because much of magnet fishing is removing detritus left in the anthropocene
This is one of the feel good parts about magnet fishing
cleaning up a body of water while being out in nature and enjoying the excitement of the next unknown catch
The mystery of the next object to be hauled up from the depths
I also like to keep a knife or scissors to cut fishing line
gloves to protect myself from cuts and dirt
and a must-have is a container for sharp objects
It’s fun to use the same phrases from fishing for fish to describe magnet fishing
or “oh that’s whopper,” or my favorite from childhood was my parent yelling
get the net,” whenever me or my siblings had a big fish on the line
that big fish was just us hooked on the bottom of the lake
although instead of getting caught on the bottom
it’s usually wedging one’s magnet in between two rocks
I have found myself going swimming to help get my magnet unstuck
One of my favorite parts about magnet fishing is the detective work that goes into finding a good spot to fish
and there’s always good magnet fishing in spots where a lot of people have been fishing for actual fish
But I typically avoid those areas if there are people actively trying to catch fish
as the sploosh of my magnet might be an unwelcome guest
Now that I’ve shared a bit about my newest hobby
I hope I’ll see some of you out there on the water
Magnet fishing is one activity that reeled me in
It caught me in the fun from my very first bite; hook
