Culturology Helps Study Cultural Evolution (Science Is Lovable 70 of 72)
For problems at the individual level, solutions reinforce the behaviors that produced them. Then the behaviors that solve problems serve as models for the behaviors of others that share the problems. That is, the occurrences of reinforcing solutions for some individuals function as evocative stimuli for the imitative solution behaviors of other individuals. When contingencies on the group make these solution practices become widespread across a group, they begin to affect the group as a group, often becoming socially institutionalized (e.g., formal education of individual group members).
