{"pk":26911,"title":"Selective Information Sampling and the In-Group Heterogeneity Effect","subtitle":null,"abstract":"People often perceive their in-groups as more heterogeneousthan their out-groups. We propose an information samplingexplanation for this in-group heterogeneity effect. We analyzea model in which an agent forms beliefs and attitudes aboutsocial groups from her experience. Consistent with robust evi-dence from the social sciences, we assume that people are morelikely to interact again with in-group members than with out-group members. This implies that people obtain larger sam-ples of information about in-groups than about out-groups. Be-cause estimators of variability tend to be right-skewed, but lessso when sample size is large, sampled in-group variability willtend to be higher than sampled out-group variability. This im-plies that even agents that process information correctly – evenif they are naive intuitive statisticians – will be subject to thein-group heterogeneity effect. Our sampling mechanism com-plements existing explanations that rely on how informationabout in-group and out-group members is processed.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"information sampling"},{"word":"Judgment Bias"},{"word":"Perceptionof Variability."}],"section":"Talks: Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/22k9j1d8","frozenauthors":[{"first_name":"Elizaveta","middle_name":"","last_name":"Konovalova","name_suffix":"","institution":"Universitat Pompeu Fabra","department":""},{"first_name":"Gael","middle_name":"","last_name":"Le Mens","name_suffix":"","institution":"Universitat Pompeu Fabra","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2017-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/26911/galley/16547/download/"}]}
