The short answer
Fortune telling is one of the cognitive distortions catalogued as part of the broader cognitive therapy framework — the specific move of predicting a negative outcome and then treating that prediction as settled fact, rather than as one guess among many possible ones.
It's easy to miss in the moment because it doesn't feel like a guess. "This is going to go badly" doesn't register as a prediction — it registers as something you already know, the way you know today's date.
The research
Fortune telling is one of the cognitive distortions David Burns catalogued, building on Aaron Beck's earlier cognitive therapy framework, giving distortions names ordinary people could recognize in themselves.

How it's different from ordinary worry
Ordinary worry usually stays tagged as uncertain: you're concerned the meeting might go badly, and some part of you is still tracking the possibility it won't. Fortune telling drops that tag. The forecast gets treated with the same confidence as a memory of something that already happened, which is part of why it's so hard to argue yourself out of in the moment — you're not weighing probabilities, you're contradicting what feels like a fact.
Burns grouped fortune telling together with mind reading under the broader category of "jumping to conclusions" — both involve deciding something negative is true without the evidence to support it, one about the future and one about what other people are thinking. They tend to travel together: the fortune-telling prediction ("this will go badly") is often propped up by a mind-reading assumption ("they already think I'm not up to it").
Why it feels so convincing
Part of what makes fortune telling hard to catch is that it borrows the emotional weight of a real memory. If a similar situation went badly once, the brain treats that one data point as a strong predictor of the next one, even when the base rate doesn't support it. A single bad presentation five years ago can quietly become "presentations go badly for me," a rule the mind applies to every presentation since, without re-checking whether it's actually held up.
The prediction also tends to arrive with a full scene attached — not just "this will go badly" but a specific, detailed version of how. That vividness is doing a lot of the persuading. A vague worry is easy to dismiss; a fully imagined failure, complete with what people's faces will look like, is much harder to wave off, even though the vividness has nothing to do with how likely it actually is.

What tends to help
The most consistent finding across CBT research on this distortion isn't that you need to convince yourself the prediction is wrong — it's that treating the prediction as a hypothesis rather than a fact is often enough to loosen its grip. That's a subtle shift: not "this won't happen" but "this is a guess, and I don't actually know yet."
The other consistent finding is that fortune-telling predictions are checkable. Unlike a lot of anxious thought patterns, a specific prediction about a specific event has an actual outcome that arrives later — the meeting happens, the text gets answered, the result comes back. Most people who track their own predictions against what actually happened are surprised by how rarely the forecast turns out to be accurate, because in the moment, every single prediction feels like the reliable one.
That's the gap Mendly's tap-to-log is built around: not arguing with the fear when it shows up, but building a record of what it predicted so the pattern — rather than the feeling — can do the arguing later.
