Once a crime's severity has been judged, there is a choice regarding how to respond. In some cases in the ancestral environment there may have been benefits from future interactions with the offender which some forms of punishment may have prevented as compared to responses such as reparations or rehabilitation. Research suggests that individuals may modify what they think are appropriate forms of response to offenders based on factors that once in the past small-group environment may have indicated that they could personally benefit from continued interactions with the offender such as kinship, in-group or out-group membership, possession of resources, sexual attractiveness, expressed remorse, intentionality, and prior history of cooperation and exploitation.[1]
