Decision-making preferences for intuition, deliberation, friends or crowds in independent and interdependent societies. Proceedings Of The Royal Society B Biological Sciences, 292(2052), 20251355. https://doi.org/10.1098/rspb.2025.1355https://doi.org/10.1098/rspb.2025.1355https://cris.uarm.edu.pe/handle/123456789/171When multiple ways of deciding are laid out side-by-side, which does one favour? We conducted experiments in 12 countries (n = 3517 individuals; 13 languages; two Indigenous communities), with adults choosing among four decision strategies—personal intuition, private deliberation, friends’ advice or crowd wisdom—when working through six everyday dilemmas. In every society, self-reliant decisions (intuition or deliberation) were most commonly preferred and considered the wisest. Expectations for fellow citizens, however, were mixed: advice from friends was expected about as often as self-reliant routes. The self-reliance tilt was strongest in cultures and individuals high in independent self-construal and need for cognition, and weakest where interdependence and self-transcendent reflection were salient. The same patterns emerged when examining ratings of each strategy’s utility and oral protocols with Indigenous groups. Self-reliance appears the modal preference across cultures, but its strength is predictably tempered when cultures, and individuals within them, construe the self in relational rather than autonomous terms.enCulturaToma de decisionesNormas descriptivasTeorías popularesNormas socialesOrientación socialSabiduríahttp://purl.org/coar/resource_type/c_2df8fbb1
