Reputation is a central element of social communications, be it with human or artificial intelligence (AI), and as such can be the primary target of malicious communication strategies. There is already a vast amount of literature on trust networks and their dynamics using Bayesian principles and involving Theory of Mind models. An issue for these simulations can be the amount of information that can be stored and managed using discretizing variables and hard thresholds. Here a novel approach to… 

Reputation Communication from an Information Perspective

: Communication, the exchange of information between intelligent agents, whether human or artificial, is susceptible to deception and misinformation. Reputation systems can help agents decide how much

Information and Agreement in the Reputation Game Simulation

An agent-based model on gossip and reputation dynamics with 50 agents is used, including Bayesian knowledge updates under bounded rationality and up to the second-order theory of mind effects, to observe the occurrence of reputation boosts from fake images and the advantage of hiding one's opinion in order to become a strong information trader.

Cooperation with Bottom-up Reputation Dynamics

This work presents a model where agents can choose both how to react to reputations and how to assign the reputations of others -- making social norms emergent, showing that when agents can spontaneously adopt novel norms, a learning process will see them drift towards socially undesirable outcomes.

Effects of deception in social networks

This work uses an agent-based model to show that antisocial lying causes social networks to become increasingly fragmented and white lies can prove to be beneficial in smoothing the flow of interactions and facilitating a larger, more integrated network.

Impact of fraud on the mean-field dynamics of cooperative social systems.

The results show that cooperation based on indirect reciprocity is robust with respect to fake reputations and can even be enhanced by them, and conclude that fraud per se does not necessarily have a detrimental effect on social systems.

Maintaining trust when agents can engage in self-deception

A mathematical model is proposed of two self-deception mechanisms and their impact on the undermining of a global cooperative society and a simulation of a society of agents provided with these biases is studied.

The value of reputation

The more valuable a good reputation is in the PD, the higher the price at which it is traded in the market, and these findings have important implications for the use of reputation systems in practice.

Notions of reputation in multi-agents systems: a review

It is argued that reputation is not a single notion but one with multiple parts, and a simple simulation framework based on evolutionary game theory is described for understanding the relative strength of the different notions of reputation.

Non-Bayesian Social Learning

It is shown that, as long as individuals take their personal signals into account in a Bayesian way, repeated interactions lead them to successfully aggregate information and learn the true parameter.

Trust and manipulation in social networks

It is shown that manipulation can connect a segregated society and thus lead to mutual consensus and that manipulation fosters opinion leadership; and surprisingly agents with low trust in their own opinion might get more influential even by being manipulated.
