Title: Experts and Overconfidence

Abstract: What makes an expert different from the general population in self-assessment? Just the amount of knowledge, or metacognition as well? How will they behave when facing something they don't know and is that deviated from people's expectations for them?

Title: How ecology impacts friendship choice

Abstract: Social relationships are an essential part of human survival. Friendship evolved as a means of social coordination among non-kin to help people meet fitness goals. Although friendships afford people many opportunities, they can also come with their own set of problems. Given this propensity for friends to both hurt and help our fitness goals, how do people choose these social partners? People seem to pay close attention to traits associated with cooperation such as honesty, trustworthiness, and sincerity At the same time, people also seem able to tailor trait preferences to different group contexts based on the affordances of those contexts. However, although this work touches on the importance of group context, no work has ever examined what the role of ecologies play in shaping social partner preferences. In short, this work is designed to test whether people tailor these preferences to the environments in which they inhabit.
