People trusted wrong AI answers.<\/p>\n<p><a href=\"https:\/\/www.theregister.com\/ai-and-ml\/2026\/07\/19\/using-ai-makes-people-less-likely-to-admit-they-dont-know-something\/5274567\" target=\"_blank\" rel=\"nofollow noopener\">Researchers from three French and Italian universities found that<\/a> access to AI advice collapsed people\u2019s willingness to say \u201cI don\u2019t know\u201d from 44% to 3%. Accuracy dropped from 27% to 9%. Confidence, meanwhile, rose from 30% to 76%. \u201cPeople became much worse, the accuracy was only one third, but they were twice as confident,\u201d said Valerio Capraro, associate professor at the University of Milano-Bicocca.<\/p>\n<p><a href=\"https:\/\/osf.io\/preprints\/psyarxiv\/5y6m4_v1\" target=\"_blank\" rel=\"nofollow noopener\">The study,<\/a> authored by Capraro with Chiara Marcoccia of \u00c9cole Normale Sup\u00e9rieure and Walter Quattrociocchi of Sapienza University of Rome, deliberately used questions where AI models typically fail: visual details from films, such as the colour of a team\u2019s uniform in Bend It Like Beckham. The researchers used Step 3.5 Flash, a model that was usually wrong on these questions, precisely so any reduction in judgment could not be explained as sensible delegation to a reliable tool. Some participants who would have answered correctly on their own asked the AI and became wrong.<\/p>\n<p>Monetary incentives helped, but not much. Willingness to admit ignorance rose from 3% to 8% and accuracy from 9% to 16%, both still well below the no-AI baselines of 44% and 27%. <a href=\"https:\/\/thenextweb.com\/news\/wharton-cognitive-surrender-ai-chatbots-decisions-moot-app\" rel=\"nofollow noopener\" target=\"_blank\">Wharton researchers coined the term \u201ccognitive surrender\u201d earlier this year<\/a> to describe the same phenomenon: people accepting incorrect AI answers 80% of the time while reporting higher confidence than those working without AI. The new study adds a sharper data point. It is not just that people trust wrong AI answers. It is that the mere availability of AI suppresses the cognitive habit of recognising what you do not know.<\/p>\n<p><img decoding=\"async\" class=\"js-lazy\" src=\"https:\/\/www.newsbeep.com\/ie\/wp-content\/uploads\/2026\/05\/tnw-newsletter.png\"\/><\/p>\n<p class=\"channel-cta-title\">The \ud83d\udc9c of EU tech<\/p>\n<p class=\"channel-cta-tagline\">The latest rumblings from the EU tech scene, a story from our wise ol&#8217; founder Boris, and some questionable AI art.

He is particularly concerned about children, who are growing up with these systems before they have developed critical thinking skills. <a href=\"https:\/\/thenextweb.com\/news\/google-search-ai-overhaul-publishers-traffic-open-web\" rel=\"nofollow noopener\" target=\"_blank\">Google\u2019s AI search overhaul replaced links with confident AI-generated summaries<\/a>, and Common Sense Media this week called that design an \u201cunacceptable risk\u201d for students. The pattern is consistent: AI products are designed to answer, never to say \u201cI don\u2019t know.\u201d The humans using them are learning to do the same.<\/p>\n","protected":false},"excerpt":{"rendered":"TL;DR Researchers found AI advice suppressed judgment suspension from 44% to 3%, accuracy from 27% to 9%, while&hellip;\n","protected":false},"author":2,"featured_media":557716,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[61,60,80],"class_list":["post-557715","post","type-post","status-publish","format-standard","has-post-thumbnail","category-technology","tag-ie","tag-ireland","tag-technology"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/557715","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=557715"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/557715\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/557716"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=557715"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=557715"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=557715"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
