Cognition, Culture, and Social Evolution
竹澤 正哲 Ph.D.
Social Psychology, Cultural Evolution, and Computational Modeling
Research Focus
I study cooperation, social norms, collective intelligence, and cumulative culture from a culture-gene coevolutionary perspective, using experiments, Bayesian statistical modeling, and computational cognitive models.
Why do humans cooperate with strangers from whom they expect nothing in return?
Human culture—science, technology, language, and art—accumulates across generations into forms no individual could create alone.
Groups can sometimes make better judgments than even their best individual members—but only under the right conditions.
Human judgment is often described as biased or irrational, yet many such tendencies may be adaptive responses to uncertain natural environments.
Moral intuitions and norm internalization are often explained in terms of evolved, domain-specific psychological mechanisms.
