While schema theory motivated the original measures of automatic cognitive associations between constructs in memory, researchers soon modified these to explore a different domain: implicit attitudes about social groups that elude standard self-reports. As the so-called implicit attitude revolution gained steam, the original measurement goal got much less attention, especially in political science. We believe the schema concept – automatic cognitive associations between features of an attitude object – continues to hold great value for political psychology. We offer a retrofit of the popular implicit association test (IAT), one more efficient than many lexical tasks, to tap these associations in surveys. The new technique captures the degree to which citizens link ideas about ostensibly group-neutral policies to specific social categories. We use this measurement strategy to explore the psychological mechanisms underlying group centrism in politics, an effort that has been largely abandoned due to measurement difficulties. Results from four studies offer practical suggestions about the application of implicit measures for capturing the automatic ways people link groups to important political objects. We conclude by discussing the broader promise of implicit measurement of group schemas, not just implicit affect, for political psychology.
