A tracker for the anxious predictions that almost never come true

If most of your worries never happen, the useful question isn't why you worry — it's which ones were actually right. Mendly logs the prediction the moment it shows up, one tap, so weeks later the hourly pattern can show you your own track record instead of asking you to trust your memory of it.

The research

A study tracked 29 people with generalized anxiety disorder across 30 days and found that 91.4% of their tracked worries did not come true. The same study found that when a worry's prediction failed to materialize, people tended to worry less about similar situations afterward — the tracking itself, not just the outcome, changed the pattern.

Want to understand why this happens? What is catastrophizing — and how to tell when you're doing it

What it actually looks like

Being certain the meeting is bad news before anyone's said a word.

Assuming the silence after your idea means it landed badly.

Deciding the test result will be the bad one before it's back.

Telling yourself 'this always happens to me' about something that hasn't happened yet.

Preparing an apology for a mistake you haven't confirmed you made.

Being shocked, again, when the thing you were sure would go wrong doesn't.

Forgetting, by next week, that you predicted disaster and it didn't come.

When it tends to be worst

  1. Right before you get an answer

    The minutes before a reply, a result, or a decision are when the prediction is most active, because there's nothing yet to confirm or deny it.

  2. In situations that have gone badly before

    A single past instance of a feared outcome tends to get treated as the base rate for every future version of the same situation, even when it was the exception.

  3. When you're already anxious about something else

    General anxious arousal makes new predictions feel more certain, not because the specific fear is more likely, but because the overall threat-detection system is already running hot.

What people usually try first

A general worry journal, without tracking outcomes

Writing the worry down helps in the moment, but without a step that comes back later to check whether it happened, there's no mechanism for the pattern to actually update — the journal becomes a record of fears, not a record of accuracy.

Seeking reassurance from someone else

A friend saying 'it'll be fine' addresses this one prediction, but it doesn't build a personal track record — the reassurance has to be sought again next time, since nothing about it is cumulative or yours.

Planning for the worst case in detail

Worst-case planning can reduce the fear of being unprepared, but it also rehearses the feared outcome in vivid detail, which research on worry chains suggests can make the prediction feel more likely, not less.

Anxiety isn't a bad forecaster because it's dramatic. It's a bad forecaster because it never checks its own predictions against what actually happened — which is a data problem, not a character problem, and data problems have data solutions.

Where Mendly fits in

The gap between a prediction and an outcome is exactly where Mendly's tap-to-log works: mark the fear the moment it shows up, no probability rating required. When you find out what actually happened, you'll have a timestamped record instead of a memory that's already reshaping itself to fit how anxious you feel right now. Over weeks, the hourly pattern view turns 'I'm always right to worry' into an actual ratio — which, for most people, looks nothing like the fear insisted it would.

Not quite your pattern? A conflict replay tracker for the argument that keeps happening after it's over might fit better

Apps like MindLift ask you to challenge the anxious thought with evidence as you log it. Mendly does something narrower and, for this pattern, more direct: it logs the prediction and lets time supply the evidence, rather than asking you to argue with the fear before you know the outcome.

Common questions

Do I have to remember to check whether the prediction came true?
It helps, but isn't required for the pattern data to be useful. Even just logging when predictions occur reveals how often you're in a state of anticipatory fear. Noting the outcome afterward — even loosely, even later — adds the accuracy layer, but partial follow-up is still meaningful data.
What if I only remember to log the predictions that turned out to be wrong?
That's a fair concern with any self-reported data. Logging in the moment the prediction happens, rather than reconstructing it afterward, is the best defense against this — you're marking the fear before you know the outcome, not selectively recalling it later.
Is this a CBT app?
No. There's no worksheet for weighing evidence or rating probability. Mendly logs the prediction and shows you the pattern over time — the evidence-weighing that CBT does explicitly happens implicitly, through your own accumulated data.
