{"pk":29988,"title":"When in Rome, do as Bayesians do:\nStatistical learning and parochial norms","subtitle":null,"abstract":"It’s a familiar point in anthropology that many norms are\nparochial, meaning they apply to people in certain groups (e.g.,\none’s ingroup) and not to others (e.g., one’s outgroup). One\nexplanation for such parochialism is that people are just\ninnately biased against outsiders. But it’s also possible that,\ngiven the evidence, people infer the parochiality of norms in\nstatistically appropriate ways. This paper uses a Bayesian\nlearning framework to investigate inferences of normative\nscope both experimentally and computationally. An\nexperiment in which adult participants (n = 480) viewed\nsample violations of a novel rule among novel groups reveals\nthat both sensitivity to statistical evidence and prior knowledge\nof relevant social categories are integral to computations of\nnormative scope. In tandem with the experimental results,\ncomputational analysis supports the notion that degree of prior\ninclusivity bias (i.e., an expectation that a norm will be broad,\nrather than narrow, in scope) is another key factor. Together,\nthese novel insights raise intriguing possibilities for integrating\nperspectives on norms research.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"statistical learning"},{"word":"Norms"},{"word":"moral psychology"},{"word":"Bayesian inference"},{"word":"Computational Modeling"}],"section":"Poster Session 3","is_remote":true,"remote_url":"https://escholarship.org/uc/item/5961c9qt","frozenauthors":[{"first_name":"Scott","middle_name":"","last_name":"Partington","name_suffix":"","institution":"Cornell University","department":""},{"first_name":"Shaun","middle_name":"","last_name":"Nichols","name_suffix":"","institution":"Cornell University","department":""},{"first_name":"Tamar","middle_name":"","last_name":"Kushnir","name_suffix":"","institution":"Cornell University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2020-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/29988/galley/19842/download/"}]}
