Behavioural Experiment Worksheet
A structured way to test the beliefs and predictions that drive how you act under pressure — and to see what really happens when you put them to the test.
Why testing a belief beats assuming it
Under pressure, we act on assumptions we rarely check — about how a situation will go, how we'll cope, or how others will react. A behavioural experiment turns one of those assumptions into something you can actually test, deliberately and once.
You'll name the belief, choose a real situation to test it in, and set aside the habits — the safety behaviours — that usually stop you finding out the truth. Then you'll run the experiment, record what actually happened, and compare it honestly with what you predicted.
This isn't about proving yourself right or wrong. It's about gathering evidence, so your next decision is built on what's actually true — not on what you feared might be.
A single, specific prediction
Named clearly enough that you'll know, afterwards, whether it held up.
Evidence you can trust
A record of what actually happens, to weigh against what you assumed would.
How to use this worksheet
Work through the sections in order — the experiment only holds together if the belief comes before the outcome.
Your answers save only in this browser, on this device — nothing is sent anywhere. Turn this off any time with the switch at the top.
Complete the Belief & Preparation sections before running the experiment — then come back to record the Outcome and Evaluation once it's done.

Your experiment, step by step
Four short sections, from naming your belief to seeing how it held up. The dots fill in as you complete each one.

A belief tested once is worth more than an assumption held for years.
Run this worksheet again the next time a prediction is worth putting to the test.
