For decades, researchers across the social sciences have sought to document and explain the worldwide variation in social group attitudes (evaluative representations, e.g., young-good/old-bad) and stereotypes (attribute representations, e.g., male–science/female–arts). Indeed, uncovering such country-level variation can provide key insights into questions ranging from how attitudes and stereotypes are clustered across places to why some places have stronger attitudes and stereotypes than others (including ecological and social correlates). Here, we introduce the Project Implicit:International (PI:International) dataset that uniquely propels this research forward by offering the first cross-country dataset of both implicit (indirectly-measured) and explicit (directly-measured) attitudes and stereotypes across multiple topics and years. Specifically, PI:International comprises 2.3 million tests for 7 topics (race, sexual orientation, age, body weight, nationality, and skin-tone attitudes, as well as men/women–science/arts stereotypes) using both indirect (Implicit Association Test; IAT) and direct (self-report) measures collected continuously from 2009 to 2019 from 36 country-specific websites in each country’s native language(s). We show that the IAT data from PI:International has adequate internal consistency (split-half reliability), convergent validity (implicit–explicit correlations), and known groups validity. Given such reliability and validity, we summarize basic descriptive results on the overall strength and variability of implicit and explicit attitudes and stereotypes around the world. The PI:International dataset, including both cleaned data and trial-level data from the IAT, is provided openly to facilitate wide access and novel discoveries on the global nature of implicit and explicit attitudes and stereotypes.
