Abstract
Large Language Models (LLMs) are increasingly used in decision-making, from content generation to employment screening, raising concerns about embedded biases. While biases related to gender, race, and culture have been studied, understanding age-bias and stereotypes of aging in LLMs remain underexplored. This study analyzes LLM-generated responses to prompts on aging, revealing stereotypical biases in technology proficiency, cognitive and physical decline, and job roles. Even responses that did not have an explicit age bias had mentions of stereotypes. We discuss considerations for involving older adults’ perspectives through human-in-the-loop methodologies yet exercising caution about aspects like internalized ageism. We discuss opportunities in exploring the role of educational explanations in minimizing harmful assumptions about marginalized subgroups.
