Mental subtraction of positive events is a researched gratitude technique Pink deploys against action regrets. You take something good in your life, mentally delete it, and imagine the world where it never happened. Applied to a regret, you subtract the regretted decision and trace what else disappears with it. Pink uses his own: he regrets going to law school, and going when he did — but he met his wife there. Subtract law school and you subtract his marriage, a world he doesn't want to live in. This is why action regrets fade over time and inaction regrets don't: action regrets can be silver-lined, sometimes even undone, while the road not taken offers nothing to subtract.
Origin
Pink draws on the existing research on mental subtraction of positive events as a gratitude intervention, then repurposes it as a regret-processing tool. It slots into his architecture of regret as the mechanism explaining the age curve — why action regrets recede and inaction regrets dominate as people get older.
Core principles
- 01Mentally subtract a positive event from your life and imagine the world without it — gratitude follows.
- 02It's a structured form of the downward counterfactual, an 'at least' with rigour.
- 03It works specifically on action regrets — things you did — because action regrets have downstream positives attached.
- 04Action regrets can be silver-lined and sometimes undone; inaction regrets can be neither, which is why inaction regrets dominate over time.
- 05The goal is to tamp down how much the regret bugs you, not to pretend it wasn't a mistake.
How to run it
- 1
Confirm it's an action regret
The technique needs something you actually did. Inaction regrets have no downstream consequences to subtract.
Watch out Trying to mentally subtract an inaction regret produces fantasy, not gratitude.
- 2
Trace the downstream goods
List what exists in your life today because of the regretted decision — people, skills, opportunities, chance encounters.
Pro tip Look for the accidental ones. The wife you met in the law school you regret is a bigger lever than the credential.
- 3
Subtract and imagine
Delete the decision from your history and follow the chain honestly. Picture the world where it never happened.
- 4
Ask if you'd live there
Would you take that world over this one? For most action regrets the answer is no, and the regret loses its grip.
Watch out This is a silver lining, not a retraction. The decision can still have been a mistake.

Consider undoing where possible
Some action regrets can be acted on directly — an apology, a removal, a repair. Pink's data is full of people who did exactly this.
In the wild
Pink regrets going to law school, and going when he did. Not his biggest regret, but real. Then he mentally subtracts it: a world where he didn't go to law school is a world where he never met his wife.
→ 'I don't wanna live in that world.' The regret stands, but it stops bugging him.
Among the World Regret Survey's moral regrets, a shocking number were about bullying other people when younger. Many of those respondents went back 20 years later and apologised to the people they'd bullied.
→ An action regret literally undone — the option that inaction regrets never offer.
Pink features a man in the book with a 'no regrets' tattoo who goes to get it removed.
→ The most literal possible undoing of an action regret.
Common mistakes
Using it to avoid the lesson
Mental subtraction is a downward counterfactual. Reach for it on closed regrets — on live, repeatable decisions it deletes the improvement signal.
Expecting it to work on the road not taken
Inaction regrets can't be subtracted or undone, which is precisely why they persist and grow. For those, the answer is a bias for action going forward.
Is it for you?
Best for
People chewing on a past decision — a degree, a job, a move — that has good consequences they've stopped seeing.
Not ideal for
Inaction regrets, which have no downstream positives to subtract, and live decisions where you should be running an upward counterfactual instead.
