 Norms and identities – the key arenas for constructivist study – are not rational, and as such, are left out of rationalist models and arguments.Mainstream economic models depicts actors as rational, meaning that actors have “impressively clear and voluminous,” if not absolutely complete, knowledge; the rational actor exhibits a well-organized and stable system of preferences; and possesses a strong computational skill (Herbert Simon 1955, 99).When the rational man learns, makes optimal choices according to a cost-benefit analysis that maximizes utility by minimizing risk.
