Modelling Contextualized Reasoning in Complex Societies with "Endorsements"

Abstract

In many computational social simulation models only cursory reference to the foundations of the agent cognition used is made and computational expenses let many modellers chose simplistic agent cognition architectures. Both choices run counter to expectations framed by scholars active in the domain of rich cognitive modelling that see agent reasoning as socially inherently contextualized. The Manchester school of social simulation proposed a particular kind of a socially contextualized reasoning mechanism, so called endorsements, to implement the cognitive processes underlying agent action selection that eventually causes agent interaction. Its usefulness lies in its lightweight architecture and in taking into account folk psychological conceptions of how reasoning works. These and other advantages make endorsements an amenable tool in everyday social simulation modelling. A yet outstanding comprehensive introduction to the concept of endorsements is provided and its theoretical basis is extended and extant research is critically reviewed. Improvements to endorsements regarding memory and perception are suggested and tested against a case-study.

The Room Around the Elephant: Tackling Context-Dependency in the Social Sciences

“…The cognitive correlate of the kind of situation is called the cognitive context [13]. 1 Though we, as individuals, do this unconsciously and with great facility (at least after childhood) we do not know how the brain does this and it may be that it is very hard to replicate this recognition explicitly. 2 However this ability allows for the following heuristic: to learn knowledge with respect to its cognitive context, give preferential access to that knowledge when the same cognitive context occurs.…”

“…Since the behavioural rules at the micro-level of agent-based simulation can be quite specific, some existing agent-based models have implicitly taken some aspects of context-dependency into account [1,2,18]. Each agent in such simulations …”

Simulation vs. Definition: Differing Approaches to Setting Probabilities for Agent Behaviour

“…The information that is transferred by the endorser is subjective and is validated by the receiver based on his or her understanding of the endorser and the product, process, or person. Thus, endorsements capture a "subjective but socially embedded agent's reasoning process about cognitive trajectories aimed at achieving information and preferential clarity over another, endorsed agent" ( [78]; p. 1).…”

The role for simulations in theory construction for the social sciences: case studies concerning Divergent Modes of Religiosity

“…For the DMR theory, the authors explain that ''many of its predictions are motivated by postulated causal links between ritual frequency, emotional arousal, memory, intuitive ontology, codification, transmission, group cohesion, group structure and scale, and social identity.'' It appears to me and others I have worked with (Alam, Geller, Meyer, & Werth, 2011;Latek & Mussavi Rizi, 2011;Moss & Edmunds, 2005) that more expressive agent behavior and environment design are required to represent ''codification,'' ''group cohesion,'' ''group structure,'' and ''social identity.'' Let me briefly explain my assertion against a ''multi-agent ontology'' of individualÁgroupÁintergroup.…”
