The method

Check reasoning and bias separately

Alongside interests and probabilities, examine how authority, conformity and persuasive explanations affect judgment.

When to use it

  • A group has strong consensus or decision-makers differ greatly in status.

Ask yourself

  • Are we trusting verifiable evidence, or the proposer’s authority and unanimous agreement?

Put it into action

  • Record evidence for and against, and let people form views independently before discussion.
  • Check whether several biases push in the same direction and arrange a review of contrary evidence.

Keep these limits in mind

  • Do not use bias labels to dismiss people who disagree.
  • The psychological examples are historical explanations; they have not been independently rechecked against modern experiments here.
