{"pk":27734,"title":"Sharing is not erring: Pseudo-reciprocity in collective search","subtitle":null,"abstract":"Information sharing in competitive environments may seem\ncounterintuitive, yet it is widely observed in humans and other\nanimals. For instance, the open-source software movement has\nled to new and valuable technologies being released publicly\nto facilitate broader collaboration and further innovation. What\ndrives this behavior and under which conditions can it be ben-\neficial for an individual? Using simulations in both static and\ndynamic environments, we show that sharing information can\nlead to individual benefits through the mechanisms of pseudo-\nreciprocity, whereby shared information leads to by-product\nbenefits for an individual without the need for explicit recipro-\ncation. Crucially, imitation with a certain level of innovation is\nrequired to avoid a tragedy of the commons, while the mecha-\nnism of a local visibility radius allows for the coordination of\nself-organizing collectives of agents. When these two mecha-\nnisms are present, we find robust evidence for the benefits of\nsharing—even when others do not reciprocate.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Collective search"},{"word":"Information Sharing"},{"word":"Pseudo-reciprocity"}],"section":"Publication-based-Talks","is_remote":true,"remote_url":"https://escholarship.org/uc/item/01f6j3q9","frozenauthors":[{"first_name":"Imen","middle_name":"","last_name":"Bouhlel","name_suffix":"","institution":"Universite Cote d' Azur","department":""},{"first_name":"Charley","middle_name":"M","last_name":"Wu","name_suffix":"","institution":"Max Planck Institute for Human Behavior","department":""},{"first_name":"Nobuyuki","middle_name":"","last_name":"Hanaki","name_suffix":"","institution":"Universite Cote d' Azur","department":""},{"first_name":"Robert","middle_name":"L","last_name":"Goldstone","name_suffix":"","institution":"Indiana University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2018-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/27734/galley/17374/download/"}]}
