A social experiment unveiled one of the digital era's most subtle fragilities: facile certainty. A user on the X platform posted a genuine work by Claude Monet, presenting it as a product generated by artificial intelligence. The outcome? Dozens of comments convinced it was a mediocre algorithmic imitation, devoid of soul and technique.

This phenomenon is not coincidental. Those with little knowledge of a subject tend to overestimate their own judgment—a cognitive bias known as the Dunning-Kruger effect—and the digital context amplifies this, eliminating the healthy friction that arises from confrontation with those who truly understand the matter.

The dynamic is as simple as it is disquieting: the moment we are most certain of our opinion, we are also most vulnerable to manipulation. Because we have stopped asking questions. Because the label suffices, and we no longer truly see the painting.

A lesson that extends far beyond art: in an information ecosystem saturated with artificially generated content, critical capacity is not a luxury, but a necessity. To doubt, to verify, to remain curious—even when convinced—is the only real defence against those who know how to exploit our certainties.
