Critical thinking is older than we think.
Long before modern education, philosophers challenged assumptions, questioned beliefs, and searched for truth through reflection.
Progress begins when people start questioning.
Artificial intelligence models overly affirm and validate users, even when users propose harmful or illegal actions, a new Science study finds.
The resulting effect on users is notable: Receiving advice from affirming AI made people more self-centered and less able to see the perspectives of others. Yet people prefer the overly affirming AI, which may further promote this behavior in AI models.

In the dense jungles of Panama’s Barro Colorado Island, a striking cricket stirs. Arota festae, known colloquially as a “bush cricket,” usually sports a deep green coat. But occasionally, what appears to be a hot pink mutant will emerge.
Scientists have long thought this hue was a genetic aberration—an unfortunate variant doomed to be quickly picked off by bats, lizards, and other predators.
But a new study finds the vibrant variant is merely a natural developmental stage, one that makes it all the more remarkable that this bug is able to keep from being picked off.

The domestic cat may be a far more recent arrival to Europe than previously thought, according to a recent Science study.
The findings offer new insight into one of humanity’s most enigmatic animal companions and identify North Africa as the cradle of the modern housecat.
