The costs and benefits of optimistic explanations and dispositional optimism

Explanatory style and dispositional optimism have been linked to physical health. In this issue, Peterson and Seligman and Carver and Scheier review an impressive series of studies which together suggest that there may be health risks associated with attributing bad outcomes to internal, stable, and global causes and with failing to maintain a generalized expectancy for good outcomes. We attempt to broaden the scope of these studies by describing the situational constraints on the observed relations and by presenting evidence that there may be health risks, as well as benefits, associated with dispositional optimism and an optimistic explanatory style.
