In humans, new forms of stigmergic processes have emerged through the development of online services that extensively use the digital traces left by their users. Here, we combine interactive experiments with faithful data-based modeling to investigate how groups of individuals exploit a simple rating system and the resulting traces in an information search task in competitive or noncompetitive conditions. We find that stigmergic interactions can help groups to collectively find the cells with the highest values in a table of hidden numbers. We show that individuals can be classified into three behavioral profiles that differ in their degree of cooperation. Moreover, the competitive situation prompts individuals to give deceptive ratings and reinforces the weight of private information versus social information in their decisions. date: 2023-10 date_type: published publisher: National Academy of Sciences id_number: 10.1073/pnas.2307880120 official_url: http://tse-fr.eu/pub/128606 faculty: tse divisions: tse language: en has_fulltext: FALSE doi: 10.1073/pnas.2307880120 view_date_year: 2023 full_text_status: none publication: Proceedings of the National Academy of Sciences of the United States of America (PNAS) ISSN 1091-6490 volume: vol. 120 number: n° 42 refereed: TRUE issn: 0027-8424 oai_identifier: oai:tse-fr.eu:128606 harvester_local_overwrite: number harvester_local_overwrite: volume harvester_local_overwrite: pending harvester_local_overwrite: creators_idrefppn harvester_local_overwrite: creators_halaffid harvester_local_overwrite: publication harvester_local_overwrite: publisher harvester_local_overwrite: issn oai_lastmod: 2024-04-29T08:16:58Z oai_set: tse site: ut1 citation: Bassanetti, Thomas, Cezera, Stéphane , Delacroix, Maxime, Escobedo, Ramon, Blanchet, Adrien , Sire, Clément and Théraulaz, Guy (2023) Cooperation and deception through stigmergic interactions in human groups.
