The internet is littered with advice. What’s it doing to your brain?

“Research has overwhelmingly found that advice is really beneficial, and that people tend to under-utilize advice, usually causing them to make lower quality decisions,” says Lyn van Swol, a professor of communication science at the University of Wisconsin-Madison who studies advice and information-sharing in groups. The catch, she notes, is that most of that research looks at advice from one, two, or three other people, not dozens, hundreds, or thousands of strangers on TikTok: “It’s overwhelming — it’s like a fire hose of advice.”
