However, the hypothesis is ambiguous about the stability of the resulting structures. Expanding scale may increase fragility and normative conflict, and networks of socially constructed coordination spaces may amplify imaginative disconnection from reality. Consequently, system-scale risks arise that exceed the grasp of governable tinkering.<\/jats:p>","DOI":"10.1017\/s0140525x26106426","type":"journal-article","created":{"date-parts":[[2026,9,18]],"date-time":"2026-09-18T10:03:09Z","timestamp":1789725789000},"update-policy":"https:\/\/doi.org\/10.1017\/policypage","source":"Crossref","is-referenced-by-count":0,"title":["Social tinkering generates complexity, but also system-scale fragility and collective delusions"],"prefix":"10.1017","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1813-3111","authenticated-orcid":false,"given":"Don","family":"Ross","sequence":"first","affiliation":[{"name":"University of Cape Town"},{"name":"University College Cork"},{"name":"Georgia State University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,9,18]]},"reference":[{"key":"S0140525X26106426_ref2","doi-asserted-by":"publisher","DOI":"10.2307\/j.ctvc77f0d"},{"key":"S0140525X26106426_ref3","doi-asserted-by":"publisher","DOI":"10.1177\/10597123251340889"},{"key":"S0140525X26106426_ref1","volume-title":"The gambling animal","author":"Harrison","year":"2025"}],"container-title":["Behavioral and Brain Sciences"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0140525X26106426","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,18]],"date-time":"2026-09-18T10:03:09Z","timestamp":1789725789000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0140525X26106426\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026]]},"references-count":3,"alternative-id":["S0140525X26106426"],"URL":"https:\/\/doi.org\/10.1017\/s0140525x26106426","relation":{},"ISSN":["0140-525X","1469-1825"],"issn-type":[{"value":"0140-525X","type":"print"},{"value":"1469-1825","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026]]},"assertion":[{"value":"\u00a9 The Author(s), 2026.
