Identifying Specific Gaps in Knowledge of Aging and Examining Its Relation to Biases Toward Older Adults

Accurate aging knowledge is key to reducing ageist attitudes that impact older adult well-being. We first investigated how aging knowledge and negative and positive age-bias indirectly expressed via aging knowledge responses were related to an explicitly negative ageism measure. We then identified specific gaps in the aging knowledge of emerging adults and middle-aged adults. More negative ageism correlated with less aging knowledge overall and in psychological and social, but not biological, domains. Negative ageism correlated with negative age-bias, but not positive age-bias, expressed via aging knowledge responses. Knowledge of aging was poorest regarding social and psychological aspects of aging and best regarding biological aging. Middle-aged adults had slightly, but significantly, more accurate aging knowledge and less negative age-bias than emerging adults; positive age-bias did not differ by age-group. These results suggest that effectiveness of anti-ageism educational interventions may be enhanced if focused on improving knowledge of social and psychological aging.
