Yet little work in the field of cultural evolution has examined the mechanisms that support information sharing in the face of exploitative information free-riding and information hoarding. We ran a series of online interactive experiments (N = 716) combined with computational reinforcement and social learning models to test whether the mechanism of reputation-based partner choice can effectively support information sharing. Participants in groups chose whether to (i) engage in costly innovation and (ii) whether to share the resultant knowledge. Sharers received increased reputations for sharing and participants could use reputations to select recipients of knowledge. We found strong priors for information sharing that persisted throughout the experiments in participants from both the UK and China (study 1). However, partner choice was generally too weak to explain the presence of widespread information sharing, which persisted even when we reduced the benefit of innovation (study 2), introduced exploitative bots (study 3) and removed reputations altogether (study 4). Our results suggest that indiscriminate, group-based sharing is more important for facilitating cumulative cultural evolution than discriminate reputation-based sharing.<\/jats:p>","DOI":"10.1098\/rspb.2026.0876","type":"journal-article","created":{"date-parts":[[2026,6,24]],"date-time":"2026-06-24T00:10:15Z","timestamp":1782259815000},"source":"Crossref","is-referenced-by-count":0,"title":["Limited evidence that reputation-based partner choice facilitates information sharing in humans"],"prefix":"10.1098","volume":"293","author":[{"given":"\u00c1ngel V.","family":"Jim\u00e9nez","sequence":"first","affiliation":[{"name":"University of Exeter, 1","place":["Penryn,, UK"],"department":["Centre for Ecology and Conservation,"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6457-0254","authenticated-orcid":false,"given":"Lei","family":"Chang","sequence":"additional","affiliation":[{"name":"University of Macau, 2","place":["Macau"],"department":["Department of Psychology,"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keith","family":"Jensen","sequence":"additional","affiliation":[{"name":"University of Manchester, 3","place":["Manchester,, UK"],"department":["Divison of Psychology, Communication and Human Neuroscience,"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hui Jing","family":"Lu","sequence":"additional","affiliation":[{"name":"Hong Kong Polytechnic University, 4","place":["Hong Kong"],"department":["Department of Applied Social Sciences,"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7740-1625","authenticated-orcid":false,"given":"Alex","family":"Mesoudi","sequence":"additional","affiliation":[{"name":"University of Exeter, 1","place":["Penryn,, UK"],"department":["Centre for Ecology and Conservation,"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2026,6,24]]},"reference":[{"key":"2026062320100796100_R1","first-page":"77","article-title":"Why culture is common, but cultural evolution is rare","volume":"88","author":"Boyd","year":"1996","journal-title":"Proc.
