Updating beliefs with evidence
Revise a conclusion transparently when credible information changes.
Covered in this guide
- Identify what evidence changed.
- Explain why it affects the conclusion.
- Retain justified uncertainty.
Changing a position can demonstrate strong judgement when the reason is transparent. The goal is not consistency at any cost; it is a conclusion proportionate to the best available evidence.

A forecast that ignored the new data
A team initially predicts low demand based on last year's data. Confirmed registrations then exceed capacity two weeks before launch.

Write the decision update.
Review answer guidance
The low-demand assumption is no longer supported because confirmed registrations exceed planned capacity. Increase capacity or control enrolment now, document the revised forecast and retain uncertainty about cancellations rather than defending the earlier estimate.
Belief-updating on the form
State the prior view, the new evidence, and the revised conclusion. If the evidence is weak, reduce confidence rather than swapping one certainty for another.
