Effects of executive ability on bias and ingroup perceptions in aging

Prior work on aging and prejudice has identified that declining executive ability underlies older adults' (OA') increased anti-outgroup bias. The current work, however, suggests that there may also be a motivational reason. Here, we explored the possibility that for OA with relatively lower executive ability, anti-outgroup bias may serve an ironic purpose of maximizing a fundamental social goal: maintaining ingroup positivity. OA are more motivated than young adults (YA) to maximize positivity in everyday life. This process, however, can be cognitively effortful. We tested the novel predictions that (a) OA' executive ability positively predicts their evaluations of ingroup members and (b) OA might preserve positive ingroup perceptions through anti-outgroup bias if they have lower executive ability. The present work tested these predictions using a timely example of an outgroup: Muslims. Study 1 verified that non-Muslim YA and OA identified with non-Muslims (vs. Muslims) as an ingroup. Study 2 then had 3 key findings. First, we replicated work showing a negative relationship between OA' executive ability and their anti-outgroup bias by showing a negative relationship with their anti-Muslim bias. Second, OA' higher executive ability related to their having more positive perceptions of ingroup non-Muslims. Finally, OA with lower executive ability had higher ingroup positivity by having higher anti-Muslim bias. These findings suggest that when OA lack the executive ability to directly maintain a motivational goal of being positive about themselves and their ingroups, they maintain positivity at the expense of others.
