Track Record

In an age of confident answers — from AI, from experts, from your own gut — the way to keep your judgment honest is to write down what you predict and how sure you are, then later check what really happened. Do it a while and you’ll see something most people never learn: how good your judgment actually is.

Make a prediction

What do you think will happen? (something you’ll later know the answer to)

How sure are you? 75%

Why? (optional — your reasoning, or “the AI told me so”)

How to use it well. Predict things you’ll actually find out — with a date, a number, a yes/no. Log your real confidence, not what sounds safe. Come back and resolve them honestly, even the misses. Over time the calibration is the gold: if your “90% sure” only comes true 60% of the time, you’re overconfident — and knowing that is the beginning of better judgment. It pairs with the Your Call experiences: don’t just trust a confident answer — including your own. Your data lives only in this browser; export it to keep a copy or move it.
