Write an Update Rule Before New Evidence Arrives

Openness to evidence becomes concrete when you name what could change your view.

Openness to evidence becomes concrete when you name what could change your view. An update rule helps distinguish information relevant to a judgment from interesting background. Writing it beforehand also reduces the temptation to reinterpret every outcome as confirmation.

State the current view

Record your conclusion, confidence, and supporting observations. Keep it narrow: this group helps me solve unfamiliar algebra problems is more testable than study groups are good. Separate performance evidence from impressions such as meetings feel productive. Note uncertainty about difficulty and extra individual practice. A dated starting point prevents a new result from silently changing what you remember believing before it arrived.

Specify possible changes

Describe what would strengthen, weaken, or complicate the conclusion. You might expect better independent work on several comparable problems. Identify alternative explanations affecting interpretation. The rule need not be numerical, but it should prevent every outcome from conveniently supporting your original view. Include evidence that would justify a narrower claim rather than complete acceptance or rejection. This makes revision more realistic than treating beliefs as all-or-nothing commitments.

Update proportionately

Compare observations with the rule. Perhaps discussion improves explanation without improving independent problem selection. Record that finding and choose a next action. In conversation, explain the evidence behind your revision so others can follow it. Beginners can examine one modest belief about a routine. Experienced learners can review several updates and ask whether they consistently demand stronger evidence against preferred conclusions than against conclusions they initially disliked.

Put it into practice

Put it into practice

  1. Choose a belief about your routine.
  2. Write evidence that would raise confidence and evidence that would lower it.
  3. Collect one relevant observation this week, revise the conclusion, and explain what changed as well as the uncertainty that remains.
Take this with youName what would change your mind before results arrive, then revise in proportion to what you actually learn.
