The method behind the tool
The Forced Choice is built on two well-worn findings: people compare far better than they score, and fewer options make a decision possible. Everything else is the interface.
Ask someone to rate nine priorities out of ten and you get a wall of sevens and eights. Ask them which of two matters more and the answer arrives almost instantly. This is the oldest finding in psychometrics: Thurstone's law of comparative judgment showed that relative judgments between two items are far more consistent than absolute ratings on a scale. The Forced Choice never asks you to score anything. It only ever asks: this one, or that one?
The most common request for a tool like this is an "equal" button. It would defeat the point. You arrived carrying nine things that all feel equally urgent — that is precisely the state the tool exists to break. Refusing the tie is the active ingredient. The mild discomfort you feel picking one is the decision actually being made, rather than deferred again.
Iyengar and Lepper's 2000 study on choice overload found that people faced with an extensive set of options were markedly less likely to choose at all than those given a small set — and were less satisfied with whatever they did pick. Later work has narrowed when the effect holds, but the direction is intuitive to anyone who has stared at a full task list at 9am. Reducing the field is not a shortcut. It is the thing that makes action possible.
Three is not a magic number and we won't pretend it is. It is small enough to hold in your head without a list, small enough that a bad day doesn't invalidate the week, and large enough that you don't feel you've abandoned your life. If four or two suits you better, the ranking is right there — the cut line is the only part that's arbitrary.
Comparing every possible pair of ten items takes forty-five comparisons. Instead, the tool runs a merge sort and asks you to resolve each comparison it genuinely needs — roughly twenty-four for ten items. The order it produces is a complete ranking, built from your own answers, without asking you the same thing twice.
This is a decision-structuring tool. It is not an assessment, a diagnosis, or a measure of you. It does not score your personality, your productivity, or your mental health, and nothing it outputs should be read as clinical information. If what's stopping you is heavier than a crowded week — persistent low mood, anxiety, burnout — a tool cannot substitute for a professional.
Ten things you're carrying. Eight minutes. Three left standing.
