En mars 2026, deux jurys am\u00e9ricains ont rendu des verdicts mettant en cause de grands acteurs du num\u00e9rique pour des risques li\u00e9s \u00e0 la sant\u00e9 mentale et \u00e0 la s\u00e9curit\u00e9 des jeunes utilisateurs. En Californie, un jury a jug\u00e9 Meta et Google responsables de la d\u00e9pression et de la suicidalit\u00e9 d\u2019une jeune femme, estimant que les plateformes Instagram et YouTube n\u2019informaient pas suffisamment les utilisateurs des risques associ\u00e9s. Au Nouveau-Mexique, un autre jury a d\u00e9clar\u00e9 Meta responsable pour avoir tromp\u00e9 les utilisateurs sur la s\u00e9curit\u00e9 de ses produits pour les jeunes et pour avoir permis l\u2019exploitation sexuelle d\u2019enfants. Ces d\u00e9cisions devraient faire l\u2019objet d\u2019appels et ne tranchent pas les d\u00e9bats scientifiques en cours sur les effets des technologies num\u00e9riques sur la sant\u00e9 mentale des jeunes, mais elles illustrent le r\u00f4le du contentieux comme outil de r\u00e9v\u00e9lation de risques \u00e9mergents et de d\u00e9clencheur potentiel de r\u00e9gulation, tout en restant r\u00e9trospectif, lent et limit\u00e9 \u00e0 des cas sp\u00e9cifiques. <\/p>\n
Parall\u00e8lement \u00e0 ces contentieux centr\u00e9s sur les r\u00e9seaux sociaux, les chatbots d\u2019intelligence artificielle \u00e0 usage g\u00e9n\u00e9ral se diffusent rapidement aupr\u00e8s des jeunes. Selon des donn\u00e9es d\u2019enqu\u00eate du Pew Research Center collect\u00e9es en 2025 aux \u00c9tats\u2011Unis, 64 % des adolescents d\u00e9clarent utiliser des chatbots d\u2019IA, dont environ 3 sur 10 quotidiennement. Si la majorit\u00e9 des usages concerne des t\u00e2ches pratiques, 16 % des adolescents indiquent les utiliser pour des conversations sociales et 19 % pour des conseils en sant\u00e9 mentale. Ces \u00e9volutions soulignent des enjeux de politique publique en mati\u00e8re de protection des mineurs, d\u2019information sur les risques, de r\u00e9gulation des services num\u00e9riques et d\u2019adaptation des cadres juridiques face \u00e0 une adoption rapide de nouvelles technologies par les jeunes, dans un contexte d\u2019incertitudes scientifiques persistantes sur leurs effets. L\u2019analyse pr\u00e9sent\u00e9e est diffus\u00e9e dans le cadre de la s\u00e9rie de publications externes du RAND Corporation, institution de recherche \u00e0 but non lucratif sp\u00e9cialis\u00e9e dans l\u2019appui \u00e0 la d\u00e9cision publique.(contenu r\u00e9sum\u00e9 en fran\u00e7ais par l’IA)\u00a0Lire la Suite<\/a><\/p>","protected":false},"excerpt":{"rendered":" En mars 2026, deux
