Abstract
A process called “actuarial prejudice” is discussed. Actuarial prejudice is a cognitive bias, based on available information about a group from the past and the present, that causes individuals to expect inferior performance from persons who belong to the group. The process, in part, explains why both women and men expect relatively low achievement from women and why women are less likely to achieve than are men. Hypotheses are proposed for future research to test the implications of this process.
