Within-network brain connectivity during a social optimism task is related to personal optimism and optimism for in-group members.

ABSTRACT: Optimism bias is the tendency to believe desirable events are more likely to happen than undesirable ones. People often display optimistic biases for themselves (personal optimism), but also for members of groups they like or identify with (social optimism). However, the neural bases of and connections between these two concepts are poorly understood. The present study hence used both questionnaires and a social optimism task performed during magnetic resonance imaging to investigate how network connectivity associates with personal and social optimism biases. Using sparse canonical correlation analysis, we found that a behavioral dimension that included both in-group optimism bias and personal optimism bias was positively associated with a dimension of network connectivity. This dimension
