Epistemology and the theory of problem solving

Problem solving has recently become a central topic both in the philosophy of science and in cognitive science. This paper integrates approaches to problem solving from these two disciplines and discusses the epistemological consequences of such an integration. The paper first analyzes problem solving as getting a true answer to a question. It then explores some stages of cognitive activity relevant to question answering that have been delineated by historians and philosophers of science and by cognitive psychologists and artificial intelligencers. The traditional opposition between discovery and justification is challenged. It is suggested that epistemology may be conceptualized, in part, as the critical assessment of problem-solving strategies.     

Going to extremes for one's group: the role of prototypicality and group acceptance

To explore who goes to aggressive and antisocial extremes on behalf of their group we primed perceptions of (a) group prototypicality (peripheral vs. central) and (b) ease of acceptance by the group. Participants were members of self‐significant groups—fraternities and sororities (N = 218). Drawing on social identity theory, uncertainty‐identity theory and the social identity theory of influence through leadership, we found, as predicted, that peripheral members who believed it was easy to be accepted were most likely to intend to engage in and support antisocial and aggressive intergroup behaviors. This effect was somewhat stronger among males than females, and strengthened among the most highly identified participants. The research's potential for understanding socially harmful intergroup violence is noted.     

Explaining White Opposition to Black Political Leadership: The Role of Fear of Racial Favoritism

Despite the election of America's first Black president, most non‐Hispanic Whites continue to oppose Black political leadership. The conventional explanation for White opposition is sheer racial prejudice, yet the available empirical evidence for this theory is inconsistent. I test an alternative theory that Whites perceive Black political leaders as a threat to their group's interests. Using a new survey measure and nationally representative panel data covering the 2008, 2010, and 2012 U.S. elections, I find that a majority of Whites perceive Black elected officials as likely to favor Blacks over Whites. Moreover, fear of racial favoritism predicts support for Barack Obama in both cross‐sectional models and fixed‐effects models of within‐person change, controlling for negative racial stereotypes. I replicate these findings using a separate cross‐sectional survey fielded after the 2014 election that controls for racial resentment. Collectively, these results suggest that perceptions of conflicting group interests—and not just prejudice—drive White opposition to Black political leadership.
