How to Improve Your Prediction Accuracy

1. Start from the base rate

Before you reason about the specifics, ask how often this kind of thing happens in general. If underdogs of a certain size win roughly one game in ten, your starting point for any single upset is around 10% — and the burden is on your specific evidence to move you away from it. Beginners tend to over-weight a vivid story and ignore the boring historical rate; experienced forecasters anchor on the base rate first and adjust carefully.

2. Always put a number on it

“Probably” is not checkable; “70%” is. Committing to a specific probability forces you to be honest with yourself and makes it possible to learn later whether you were well-calibrated. If numbers feel unnatural at first, use a simple scale — very unlikely, unlikely, coin flip, likely, very likely — and attach rough percentages to each. The habit matters more than the precision. For the underlying ideas, see Understanding probability and implied odds.

3. Break big questions into smaller ones

Hard predictions often become manageable when you decompose them. Instead of guessing whether a team wins a tournament in one leap, estimate the pieces: do they get out of the group, win a likely quarter-final, and so on — then combine. Breaking a question into independent parts reduces the chance that a single strong emotion drives the whole estimate, and it usually surfaces exactly where your uncertainty really lives.

4. Actively look for the other side

The fastest way to improve is to argue against yourself before you commit. Write down the single best reason you might be wrong, and take it seriously. Seek out sources that disagree with your view rather than ones that comfort it. This one habit does more to counter confirmation bias than any amount of extra research on the side you already favour.

5. Read the question exactly as written

On a platform where outcomes settle against the literal wording of a question, many “wrong” predictions are really misreadings. Check what precise event is being predicted, the exact deadline, and where the result will be confirmed. A prediction that resolves on an official final result is different from one that resolves on a provisional figure. When a question is genuinely ambiguous, that is a reason for caution — see the Prediction Standards for how vague questions are handled.

6. Keep a record and review your misses

The predictors who improve fastest are the ones who look back. Keep a note of what you predicted, the probability you assigned, and — most importantly — why. When an outcome lands, revisit it: were you wrong because of bad luck on a call that was reasonable, or because your reasoning had a flaw you can fix? Only the second kind teaches you anything, and you can only tell the difference if you wrote down your reasoning at the time. A visible track record does part of this for you automatically.

7. Judge yourself over many calls, not one

Any single prediction can go the “wrong” way even when your reasoning was excellent — that is what uncertainty means. Resist the urge to overhaul your whole approach because of one miss, or to feel like a genius because of one hit. Calibration and consistency only reveal themselves across dozens of predictions. Patience with the process is itself a forecasting skill.

8. Manage your own psychology

Emotion is the quiet enemy of accuracy. You will predict worse on questions about the team you love, the creator you follow, or the outcome you are hoping for. Notice when you have a stake in believing a particular answer, and be extra sceptical of yourself there. If participating ever stops being fun or starts to feel like chasing a result, step away — good decisions come from a calm head. Our Responsible Participation guide has more on keeping it healthy.

Putting it together

None of these habits require special knowledge — they require discipline. Start from base rates, commit to a number, decompose hard questions, argue the other side, read carefully, keep a record, and judge yourself over the long run. Do that consistently and your accuracy will improve in a way that shows up clearly in an honest track record.
