Inversion: solving decisions by working backwards

March 2026 · 4 min

You have been sitting with the same question for weeks. Maybe it's a job, a move, a relationship, a business idea. You keep asking yourself what you want, and the honest answer is that you don't know. Every time you reach for it, the question dissolves. You want to be happy. You want it to work out. None of that tells you what to do on Monday. The harder you stare at "what do I want," the blurrier it gets, and you start to wonder if something is wrong with you for not knowing.

why "what do i want" so often fails

There is nothing wrong with you. The question is just badly shaped for the way your mind works. "What do I want?" asks you to imagine a future that does not exist yet and then rank versions of it against each other. That is a huge amount of invention to do on the spot. You are trying to picture a life you have never lived and feel certain about it. Wanting is also slippery. It shifts with your mood, with who you spoke to last, with how tired you are by evening.

Avoidance, by contrast, is sharp. You know what a bad week feels like. You know which version of your life would make you quietly miserable. Fear and aversion are older, faster signals than aspiration, and they point at something concrete rather than something imagined. This is why the question of what you want can leave you frozen while the question of what you dread snaps into focus almost instantly.

the mistake: chasing the perfect outcome

The common error here is treating the decision as a search for the best possible result. You line up the options and try to find the one that maximises happiness, money, meaning, all of it at once. But the best case rarely separates the choices. Most options have a decent best case, which is exactly why you can't choose between them. What actually distinguishes them is the downside, the thing that happens when reality refuses to cooperate. People who fixate on the upside also tend to tangle the decision with the outcome, judging the choice by whether it worked rather than whether it was sound. It is worth keeping those two things apart.

Inversion fixes this by turning the question over. Instead of "what is the best that could happen," you ask "what do I most need to avoid, and which path makes that least likely?" You stop designing the perfect life and start ruling out the futures you could not live with. That is a far smaller, far more answerable task.

the exercise: work backwards from the worst

Take your decision and write the question across the top of a page. Then work through these prompts slowly, in order, writing your answers down rather than just thinking them.

One: imagine it is two years from now and this choice has gone badly. Not catastrophically, just quietly wrong. Describe that life in three or four plain sentences. What does an ordinary Tuesday feel like? Two: name the single worst part of that picture. Be specific. "I'm bored" is weaker than "I haven't learned anything new in eighteen months and I've stopped trying." Three: do the same for each option you are weighing, including the option of doing nothing, which is itself a choice with its own downside. Four: look at the worst cases side by side and ask which one you could not live with, and which you could accept even if it arrived.

The option whose downside you can carry is usually your answer, or close to it. You are not picking the brightest future. You are picking the one whose failure you could survive and respect yourself through. If the worst cases still feel evenly matched, that tells you something useful too: this may be a genuinely close call where either path is defensible, and your job shifts from choosing perfectly to committing fully.

Inversion pairs well with other tools. Once you have named the downside, you can ask how much it will matter on different horizons, which is the work behind the 10/10/10 rule for ten minutes, ten months and ten years from now. And as you write the worst cases out, keep reminding yourself that a sound decision can still produce a bad result, because the future has its own say.

a softer note to end on

Working backwards from the worst can feel grim at first, but most people find it oddly calming. Naming what you dread strips the vagueness out of a choice and replaces a hundred imagined futures with one clear thing to steer away from. You don't have to know exactly what you want. You only have to know what you refuse to drift into.

If you want to think a decision through this way without doing it alone in your own head, Selaro can hold the questions with you, walk through each worst case, and help you see which downside you can actually live with. It won't decide for you. It will help you decide for yourself.
