The offspring cannot rely on its parents for disinterested guidance. One expects the offspring to be preprogrammed to resist some parental manipulation while being open to other forms. When the parent imposes an arbitrary system of reinforcement (punishment and reward) in order to manipulate the offspring to act against its own best interests, selection will favor offspring that resist such schedules of reinforcement.

A very disturbing feature of overconfidence is that it often appears to be poorly associated with knowledge - that is, the more ignorant the individual, the more confident he or she might be.
