Individual differences in decision making are a topic of longstanding interest, but often yield inconsistent and contradictory
results. After providing an overview of individual difference measures that have commonly been used in
judgment and decision-making (JDM) research, we suggest that our understanding of individual difference effects in
JDM may be improved by amending our approach to studying them. We propose four recommendations for improving
the pursuit of individual differences in JDM research: a more systematic approach; more theory-driven selection
of measures; a reduced emphasis on main effects in favor of interactions between individual differences and decision
features, situational factors, and other individual differences; and more extensive communication of results (whether
significant or null, published or unpublished). As a first step, we offer our database — the Decision Making Individual
Differences Inventory (DMIDI; html://www.dmidi.net), a free, public resource that categorizes and describes the most
common individual difference measures used in JDM research.
