Reputation-like inference in domestic dogs (Canis familiaris).

Humans frequently interact with strangers absent prior direct experience with their behavior. Some conjecture that this may have favored evolution of a cognitive system within the hominoid clade or perhaps the primate order to assign reputations based on third-party exchanges. However, non-primate species' acquisition of skills from experienced individuals, attention to communicative cues, and propensity to infer social rules suggests reputation inference may be more widespread.
