PsychTable.org is a new online, mass-collaborative tool for the social sciences that aggregates evidence for and classifies the evolved psychological adaptations (EPAs) that have been proposed to comprise the human mind. This article provides an overview of the need for this reference tool and how it can benefit researchers who incorporate the behavioral sciences into their work. The article walks the reader through a hypothetical use case for PsychTable.org and describes the features of the website. PsychTable.org is intended to help key stakeholders better understand the linkages between EPAs and political behavior, public policy, and ethics.
