The advent of implicit measures of social cognition introduced a paradoxical result: Compared to members of higher-status groups, members of lower-status groups often show no implicit ingroup preference, sometimes even showing outgroup preference, a result rarely observed on explicit measures. Prevailing theories have provided macro-level accounts, often in terms of system-justifying tendencies, but the various cognitive processes that could produce such an absence of ingroup preference among lower-status groups have not been directly decomposed. In this paper, we address this gap via formal process modeling applied to data from 5.7 million respondents collected across 16 years and 6 social categories. We find that, among lower-status groups, ingroup-affirming evaluations are accompanied by more pronounced self-regulatory control than outgroup-affirming evaluations, a regulatory asymmetry absent among higher-status groups. For example, evaluations affirming Black and overweight ingroups were accompanied by heightened self-regulatory control, whereas a comparable self-regulatory pattern was not observed for evaluations affirming White and nonoverweight ingroups. The evidence points to a previously unrecognized role for self-regulatory control in the absence of ingroup preference, suggesting that the cognitive imprint of social hierarchies may extend beyond evaluative associations to the regulatory processes that govern their expression.<\/jats:p>","DOI":"10.1073\/pnas.2600311123","type":"journal-article","created":{"date-parts":[[2026,9,9]],"date-time":"2026-09-09T16:26:36Z","timestamp":1788971196000},"update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":0,"title":["A role for self-regulatory control in the absence of ingroup preference"],"prefix":"10.1073","volume":"123","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5040-1644","authenticated-orcid":false,"given":"Samuel A.
