AI access makes people almost entirely unwilling to say "I don't know," study finds

A study with more than 3,000 participants shows that just having access to AI answers nearly eliminated people's willingness to say "I don't know." In one experiment, it dropped from 44 to 3 percent, even though the AI was almost always wrong. Participants who used AI felt more confident but were correct only about a third as often as those without it.
