Applying implicit social cognition to risk research, I performed a series of studies for the purpose of (a) cross-national and (b) inter-generational comparisons of implicit as well as explicit attitudes toward risk and (c) an assessment of the predictive validity of a newly developed implicit measure of stock investment. Study 1 demonstrated a possibility of utilizing the implicit measures of risk attitude as a useful tool complementary to the existing self-report risk measures for understanding cross-cultural similarities and differences in risk. Study 2 replicated the utility of the implicit measures of risk attitude in the form of the known-group validity by showing the marked age differences that cannot be captured by the corresponding explicit measures. Study 3 illustrated that the implicit stock investment measure, designed to measure the associative strength of My stock investment with Aggressive- versus Conservative-related words, provided incremental variance in stock investment performance of undergraduates majoring in financial engineering when interacting with explicit measures of financial risk taking. The theoretical and practical implications of the findings are discussed.
