In the last decade, psychology faced a serious crisis, called the reproducibility problem. To solve the problem, several methodological and institutional changes have been proposed and implemented such as the promotion of replication studies and publication of negative results, the introduction of a preregistration system in academic journals, and the implementation of novel statistical methods for suppressing false-positive results. In this paper, based on a previously proposed formal model of population dynamics of scientific discovery, I first explain that these changes are insufficient for avoiding the reproducibility problem. Based on two examples in social psychology, I also discuss that what is necessary for fundamental reformulation of psychology is rigorous modeling, which has already been widely applied in many scientific fields outside psychology.

It has been argued that people selectively use two strategies, projection and stereotyping, to infer the mental state of others. Through a series of studies, Ames (2004) confirmed the hypothesis that people project their own mental state to the other when the target person is perceived to be similar to oneself, while the stereotype of a group or category to which the target person belongs is used for mental state inferences when the target is perceived to be dissimilar. Four replication studies of Ames (2004), however, consistently provided counterevidence against this hypothesis. Participants employed projection consistently, regardless of the perceived similarity to the target person. This result suggests that further examination of conditions that trigger different mental state inference strategies is needed.

How does a reciprocal communal sharing system come into existence in a sustainable form in human societies? The anthropological literature has provided two explanations for the origin of communal sharing under uncertainty: risk reduction by social sharing (Kaplan & Hill, 1985) and tolerated theft (Blurton Jones, 1984, 1987; Winterhalder, 1986, 1996). In this paper, we aim to develop a third explanation focusing on the emergence of a communal sharing norm. A communal sharing norm here refers to a social norm designating uncertain resources as common properties. A series of computer simulations based on an evolutionary game framework suggests that such a communal sharing norm is indeed evolvable. We argue that the evolutionary game analysis can be a powerful tool in cognitive science to derive empirical hypotheses concerning various cognitive and behavioral mechanisms.
