Morin's counter to catastrophising is symmetry rather than positivity. When something is changing we think about all the bad things that could happen — even for something trivial like switching software. We underestimate ourselves and overestimate the difficulty. The intervention is to step back and ask what the chances are it works out better than imagined, then actively argue that side. The brain then registers that yes, there's a one-in-a-hundred chance it goes badly, but maybe also a chance it goes well. She illustrates the emotional bias sharply: told there's a one-in-a-hundred chance of a deadly disease, you think you'll be the one; told there's a one-in-a-hundred chance of winning a million dollars, you think it won't happen to you. Same odds, opposite conviction.
Origin
One of Morin's tools for countering negative thoughts, drawn from her therapy practice and included in her work on mental strength. It's a practical application of the observation that emotional state — not probability — drives our conviction about outcomes.
Core principles
- 01We underestimate ourselves and overestimate how challenging change will be.
- 02The brain converts a possibility into a certainty — 'this is 100% true that this thing will happen.'
- 03Emotions bias the direction: when nervous we're convinced the bad outcome will happen to us; when excited we're convinced the good one won't.
- 04The goal is a balanced perspective, not forced positivity.
- 05Deliberately generating evidence for the good outcome restores the missing half of the picture.
How to run it
- 1
Catch the horrible prediction
Notice the moment your brain starts listing everything that could go wrong about a change. It might be something small — a software migration — and the reflex is 'it's going to be too hard.'

Step back and ask the counter-question
Ask: what are the chances this might work out better than I'm imagining? This is a genuine question, not a pep talk — you're requesting the data your brain skipped.

Argue the opposite case with evidence
Actively make the case that something amazing might happen and supply reasons. Here's some evidence that it may turn out better than I'd expect. Your brain accepts the balanced version once it has material to work with.
Pro tip This often surfaces creative solutions, because you're finally searching the solution space instead of the failure space.

Check which emotion is doing the forecasting
When nervous, we're convinced the unlikely bad thing will happen to us. When excited, we're convinced the unlikely good thing won't. Recognise the emotional tilt and mix some logic back in.
Watch out Don't overcorrect into blind optimism — the target is balance, not a new certainty.
In the wild
Morin's illustration: if someone said there's a one-in-a-hundred chance you'll get a deadly disease, you think 'I'm going to be that one in a hundred.' If someone said there's a one-in-a-hundred chance you'll win a million dollars, you think 'well, that won't happen to me.'
→ Identical odds produce opposite convictions, exposing that emotion — not probability — is driving the estimate, which is precisely what arguing the opposite corrects.
You're changing your software program and immediately think it's going to be too hard. You underestimate your own adaptability and overestimate the difficulty of the transition.
→ Arguing the opposite gives a more balanced perspective so you don't just believe the negative — and often breaks through the imaginary obstacle entirely.
Common mistakes
Converting a possibility into a certainty
We convince ourselves this is 100% true, that this thing is going to happen. Once the forecast hardens into fact, no amount of evidence gets in — you have to reopen the question deliberately.
Confusing this with positive thinking
The goal isn't to believe it will go well. It's to expand your mind to say 'or maybe something amazing will happen too' so the perspective is balanced. Swapping pessimistic certainty for optimistic certainty solves nothing.
Is it for you?
Best for
Anyone facing a change — new software, new role, new project — who is stuck in downside-only forecasting
Not ideal for
Genuine high-stakes risk assessment where downside modelling is the correct discipline
