Reply to Cook and Over: Social learning and evolutionary mechanisms are not mutually exclusive

We thank Cook and Over (1) for their response to our recent article, where we find that unique experiences drive individual differences in impression formation (2). Overall, our theoretical positions are similar: We suggest that social associative learning underlies this core finding (2), and Cook and Over (1) clearly agree. Here, we take the opportunity to address a critical misunderstanding, namely that evolutionary and social learning mechanisms are mutually exclusive. We propose that both processes shape impression formation.
