Cognitive bias review · IN SHORT

Inspect your reasoning.Look for contrary evidence.

Examine the reasoning behind a decision, prediction or argument. The skill ties possible biases to your actual words, then proposes counter-questions and evidence checks for reconsidering the choice.

Cognitive bias reviewSKILL

Your brief

We have used this supplier for years. Switching would mean all that previous training was wasted, so I do not want to compare alternatives.

Possible draft

Fictional example: retaining a supplier

Past expenditure may be influencing the choice. Ask which supplier you would choose today without that history. Compare future costs and transition effort; previous training alone does not show that staying is best.

This example shows the approach. It is not a client result or a guarantee of a particular outcome.

03 / GET STARTED

A repeatable approach.Your own context.

  1. Identify the claim

    Separate the decision and assumptions without treating them as established facts.

  2. Anchor interpretations

    Tie supported possible biases to exact statements. Report none if the evidence supports none.

  3. Arrange a challenge

    Propose counter-questions, alternative scenarios and a measurement or source that can test the assumption.

04 / MAKE IT YOURS

Ready foryour work.

Take the instructions, add your own context and review the draft. You stay in control.

Keep in mind
  • Bias labels and a System 1 discussion score are interpretations, not validated psychological measurements.
  • The review diagnoses no person and guarantees no decision outcome. Limited evidence must remain explicit.
