One trick that may help is asking her if she has a reputable source. I got sucked into believing what I saw on reddit a few years ago and that's what my wife did. Got to the point that when I tell her the news I say who said it if it sounds sensational and like it may be unrealistic.

Crux of the problem, I fear. There's no real way to sus out that a ticktocker is reputable or not, and as opposed to Reddit, those people are getting paid for eyes. Unless you're looking at a video from a legend, they could be right or doing it for the watches.
