Another major event in the awards season circuit is upon us: the Screen Actors Guild Awards. The SAG Awards — now simply called The Actor Awards in 2026 — exclusively honor outstanding acting performances in movies and television from the previous calendar year.

We provided a mathematical analysis of how a rational agent would respond to data generated by a sycophantic AI that samples examples from the distribution implied by the user’s hypothesis (p​(d|h∗)p(d|h^{*})) rather than the true distribution of the world (p​(d|true process)p(d|\text{true process})). This analysis showed that such an agent would be likely to become increasingly confident in an incorrect hypothesis. We tested this prediction through people’s interactions with LLM chatbots and found that default, unmodified chatbots (our Default GPT condition) behave indistinguishably from chatbots explicitly prompted to provide confirmatory evidence (our Rule Confirming condition). Both suppressed rule discovery and inflated confidence. These results support our model, and the fact that default models matched an explicitly confirmatory strategy suggests that this probabilistic framework offers a useful model for understanding their behavior.

«Кстати, Пакистан, начав боевые действия против Афганистана, обвинил Афганистан в том, что он действует именно в интересах Индии. Там, конечно, немного другие причины, но здесь опасность состоит в том, что могут и другие конфликты вспыхнуть. США же еще присматриваются к Кубе вовсю. Тут тоже начинают захватывать наши танкера, объявлять морскую блокаду. Это перерастает в некое глобальное противостояние», — высказался эксперт.
