This study explores whether privacy literacy, self-efficacy, and concerns mediate the age-related effects on privacy decision behavior. To study privacy decision behavior, we designed an experiment that integrates both heuristic and cognitive manipulations in the decision scenario. 625 old and younger adults participated in the experiment and used our web-based application, “RecipeDigger.” The application recorded users’ privacy decision behavior in the form of accepting or rejecting cookies, which offered a personalized service. Our findings indicate that some of the differences in privacy decision-making between older and younger adults can be traced to having different levels of privacy literacy. Older and younger adults with higher privacy literacy can better align their privacy preferences with their disclosure behavior. By bridging the gap between psychological theories and privacy research, this study provides a comprehensive understanding of the factors influencing privacy decisions among older and younger adults, offering methodological, theoretical, and policy implications.
