In this study, the authors explored whether wisdom-related performance could be enhanced by an instruction referring to the abstract concept of wisdom ("try to give a wise response"). The authors used three levels of activation of the concept of wisdom as well as intelligence-activation and control conditions in a heterogeneous sample of three age groups (N = 318). Results showed no general effect of the wisdom-concept instructions but did show an aptitude (resource) treatment interaction: Participants high in preparedness resources associated with wisdom exhibited some gains, whereas the performance of resource-low participants actually declined after the instruction. Implications and consequences with respect to ways of enhancing the expression of wisdom-related knowledge are discussed.
