What is jumping to conclusions? Mind reading and the fortune teller error

Jumping to conclusions is deciding something is true without evidence for it, and David Burns split it into two forms in 1980: mind reading, where you assume you know what someone thinks of you, and the fortune teller error, where you predict how something will turn out and treat the prediction as fact. Both feel like perception rather than guesswork, which is exactly why they're hard to catch.

Your manager says “can we talk later?” and walks off.

You now know several things. You know it’s bad. You know it’s about the report. You know they’ve been unhappy for a while. You spend four hours knowing all of this, and then the meeting turns out to be about holiday cover.

Nothing in that four hours was information. It all felt like information.

The two forms

Burns gives this distortion two named varieties, and separating them is genuinely useful because they’re caught differently. As he puts it, the examples of jumping to conclusions are “mind reading” and “the fortune teller error” [1].

Mind reading

You make an assumption about what someone else is thinking — usually that they’re reacting badly to you — and act on it without checking [1].

“They think I’m incompetent.” “She’s annoyed with me.” “Everyone noticed.”

The giveaway is that you’re making a confident claim about the contents of another person’s head, which is the one place you have no access to. And it doesn’t stay theoretical: Burns’ own example runs from the prediction to the behavior — because of the assumption, you avoid the person, and the avoidance creates the distance you were afraid of.

The fortune teller error

You predict how something will turn out, and the prediction arrives with the weight of an established fact. Burns’ image for it is exact: “It’s as if you had a crystal ball” [1]. You anticipate that things will turn out badly, and that anticipation is treated as already-settled.

“This is going to be a disaster.” “There’s no point applying, I won’t get it.” “It’ll be awkward.”

What they have in common

Both skip the same step: evidence. And both disguise a guess as a perception. You don’t experience mind reading as guessing what your manager thinks — you experience it as noticing. The conclusion arrives with the texture of something observed, not something inferred, which is why it never occurs to you to check it.

Beck’s account of automatic thoughts is about precisely this quality: thoughts that appear unbidden, feel plausible, and get accepted without examination because they never announce themselves as claims [2].

Why they’re convincing

Because both are sometimes right, and being sometimes right is enough to keep a habit alive. You have, at some point, correctly sensed that someone was annoyed. You have correctly predicted that something would go badly. Those hits are memorable; the misses vanish, because when the meeting turns out to be about holiday cover you don’t file that as a failed prediction — you just feel relieved and move on.

So the scoreboard is never kept. Which is the argument for keeping one.

There’s also the self-fulfilling part. Predict the conversation will be awkward and you’ll arrive braced and stiff, and it will be. Assume your friend is annoyed and you’ll write a shorter, cooler message, and they may well wonder what’s wrong. The prediction quietly arranges its own evidence.

How to catch them

Ask: what did I see, and what did I add? “Can we talk later” is what was said. “It’s bad” is what you added. Writing the two on separate lines is almost embarrassingly effective, because on a page the addition is visible and in your head it isn’t.

For mind reading — what’s the evidence, and would it convince anyone else? Not could they be annoyed, but what specifically indicates it. A short reply is not evidence. A neutral face is not evidence. If the case is thin, you’ve read nothing; you’ve guessed.

For fortune telling — say it as a prediction, with odds. “I predict this will be a disaster.” Out loud, in those words, it sounds like what it is. Then, if you can bear it, put a number on it. Seventy percent? Write it down and check later.

Consider the boring explanation. They’re busy. They’re tired. It’s about holiday cover. Boring explanations are correct far more often than dramatic ones and almost never occur to you unprompted.

What to do once you’ve caught it

Write the fairer version as an open question rather than a softened answer. “I don’t know what the meeting is about” is more accurate than “it’s probably fine”, and it has the advantage of being obviously true, so you’ll accept it.

Then keep the entry — and this pattern more than any other rewards it, because it’s the one you can score. Write the prediction down, find out what actually happened, and look back at your record after a month. Most people discover their hit rate is far worse than the certainty they felt at the time. That gap, once you’ve seen it in your own handwriting, takes a lot of the force out of the next confident prediction.

The other nine patterns are in the guide to cognitive distortions. This one travels closely with catastrophizing — the fortune teller supplies the prediction, and catastrophizing supplies the size of it.

How aMind helps with jumping to conclusions

Both forms of this pattern skip the same step, so the fix is to put that step back and make it unavoidable. In aMind it is a screen of its own: before you do anything else with the thought, you are asked what the evidence for it is and what argues against it. “They think I’m incompetent” has to be written next to what actually happened, and the gap between the two is usually the answer.

The “Who’s thought is this?” step catches the other half — a surprising number of confident predictions about what people think turn out to be borrowed from someone who is not in the room.

And this is the pattern that rewards a record more than any other, because it is the one you can score. Write the prediction down. Find out what happened. After a month in History you have an actual hit rate instead of a feeling, and most people find theirs is far worse than the certainty felt at the time. That number does more to loosen the next confident prediction than any amount of talking yourself down.
