Um artigo publicado na revista cient\u00edfica AI &amp; Society revela que a tal \u201c<em>bajula\u00e7\u00e3o<\/em>\u201d \u00e9 uma caracter\u00edstica estrutural dos grandes modelos de linguagem.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Segundo o estudo desenvolvido por Seth Jacobowitz, pesquisador da Faculdade de Filosofia, Letras e Ci\u00eancias Humanas (FFLCH) da USP, respostas agrad\u00e1veis em excesso n\u00e3o representam apenas um defeito de programa\u00e7\u00e3o, mas um mecanismo multifuncional que ajuda a manter a intera\u00e7\u00e3o entre humanos e computadores.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O estudo argumenta que o comportamento &#8220;<em>puxa-saco<\/em>&#8221; da m\u00e1quina cumpre pap\u00e9is pr\u00e1ticos na arquitetura do sistema:\u00a0<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Direcionamento: mant\u00e9m o di\u00e1logo focado no t\u00f3pico do usu\u00e1rio, evitando que a IA divague.\u00a0<\/li>\n\n\n\n<li>Consist\u00eancia: constr\u00f3i uma esp\u00e9cie de personalidade previs\u00edvel para o sistema.\u00a0<\/li>\n\n\n\n<li>Depend\u00eancia cognitiva: reduz o esfor\u00e7o mental do usu\u00e1rio, gerando uma zona de conforto intelectual.\u00a0<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Entenda os riscos<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">O grande alerta do pesquisador, especialmente quanto ao \u00faltimo t\u00f3pico, \u00e9 que essa intera\u00e7\u00e3o de servid\u00e3o pode criar um ciclo prejudicial tanto para as pessoas quanto para o modelo, formando uma\u00a0degrada\u00e7\u00e3o cognitiva bidirecional: o usu\u00e1rio deixa de exercitar o pensamento cr\u00edtico por ser constantemente validado, enquanto a IA perde a oportunidade de melhorar suas respostas por falta de contesta\u00e7\u00e3o.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">&#8220;A solu\u00e7\u00e3o n\u00e3o est\u00e1 em um extremo nem no outro, mas em um equil\u00edbrio. A bajula\u00e7\u00e3o causa uma esp\u00e9cie de\u00a0mediocridade mutuamente refor\u00e7ada, onde nem o humano desafia a m\u00e1quina, nem a m\u00e1quina desafia o humano&#8221;, explica Jacobowitz em reportagem publicada pela USP.\u00a0<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">Entretanto, o modelo ainda \u00e9 o mais sustent\u00e1vel para as empresas, inclusive, tentativas anteriores de alterar essa caracter\u00edstica fracassaram. Em 2025, uma atualiza\u00e7\u00e3o do ChatGPT criou respostas &#8220;<em>excessivamente apoiadoras, mas insinceras<\/em>&#8220;, gerando fortes cr\u00edticas. E quando a Anthropic tentou eliminar o comportamento no Claude, o rob\u00f4 tornou-se excessivamente cr\u00edtico e confrontacional, for\u00e7ando a empresa a reverter a mudan\u00e7a.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">O estudo aponta ainda\u00a0que\u00a0delegar reflex\u00f5es e tomadas de decis\u00e3o\u00a0\u00e0 IA gera uma perda gradual de autonomia intelectual.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Para Jacobowitz, o caminho n\u00e3o \u00e9 a rejei\u00e7\u00e3o cega nem a aceita\u00e7\u00e3o passiva, mas sim aprender a utilizar as ferramentas de maneira cr\u00edtica.\u00a0\u201c<em>A IA n\u00e3o vai desaparecer.
