摘要

人类和其他动物经常遵循他人做出的决定,因为这些决定表明了可能选择的质量,从而产生了“社会反应规则”,也就是说,观察到一个主体做出特定选择的概率与其他个体做出的决定之间的关系。社会反应的形式可以通过考虑理性代理人的行为来理解,这些代理人寻求利用社会和私人信息最大化他们的预期效用。先前的社会反应衍生假设代理观察群体中的所有其他人,但真正的互动网络通常以稀疏连接为特征。在这里,我分析了理性主体的可观察行为,这些理性主体参与了群体中一部分人的决策。这揭示了基于高度简化的社会信息的稀疏连接网络中的自适应策略,即选择每个选项的观察到的代理数量的差异。当代理人采用这种策略时,集体结果和决策效能由决策时的社会连通性控制,而不是代理人习惯的社会连通性,这为在实验室中观察到的社会性提供了重要警告,并为高度连接的在线社区的社会动态提供了基础。

Collective decision-making under changing social environments among agents adapted to sparse connectivity
Humans and other animals often follow the decisions made by others because these are indicative of the quality of possible choices, resulting in ‘social response rules’, that is, observed relationships between the probability that an agent will make a specific choice and the decisions other individuals have made. The form of social responses can be understood by considering the behaviour of rational agents that seek to maximise their expected utility using both social and private information. Previous derivations of social responses assume that agents observe all others within a group, but real interaction networks are often characterised by sparse connectivity. Here, I analyse the observable behaviour of rational agents that attend to the decisions made by a subset of others in the group. This reveals an adaptive strategy in sparsely connected networks based on highly simplified social information, that is, the difference in the observed number of agents choosing each option. Where agents employ this strategy, collective outcomes and decision-making efficacy are controlled by the social connectivity at the time of the decision, rather than that to which the agents are accustomed, providing an important caveat for sociality observed in the laboratory and suggesting a basis for the social dynamics of highly connected online communities.
