The assumption audit

Surface and question the beliefs that are driving a current decision or conflict.

Key takeaways

  • What it is: Surface and question the beliefs that are driving a current decision or conflict.
  • Why it works: Most emotional reactions and habitual decisions are driven by assumptions that feel like facts — "that’s just how things are." Making those assumptions explicit interrupts automatic processing and subjects them to evaluation, which is the cognitive mechanism behind both Socratic inquiry and CBT’s cognitive restructuring.
  • Evidence: Established clinical or therapeutic practice.
  • Avoid: Naming the assumption but never genuinely questioning it — writing "I assume X" and immediately reasoning why X must be true anyway.

Why it works

Most emotional reactions and habitual decisions are driven by assumptions that feel like facts — "that’s just how things are." Making those assumptions explicit interrupts automatic processing and subjects them to evaluation, which is the cognitive mechanism behind both Socratic inquiry and CBT’s cognitive restructuring.

How to do it

  1. 1Pick a decision, conflict, or strong reaction you are currently carrying.
  2. 2Write "I am assuming that…" and complete the sentence five times without filtering.
  3. 3For each assumption, ask: "How do I know this is true? What would it mean if it weren’t?"
  4. 4Identify which assumption, if false, would most change your response.

What the evidence says

Clinical practice

Surfacing and evaluating automatic assumptions is the core mechanism in cognitive restructuring, which has strong RCT support for reducing distress across anxiety and depression.

Honest caveat: The clinical evidence is for therapist-guided cognitive restructuring; self-directed assumption audits are plausible but less formally tested.

Common mistake

Naming the assumption but never genuinely questioning it — writing "I assume X" and immediately reasoning why X must be true anyway.

IX Coach asks "what are you assuming here?" at the moment a decision or conflict appears in your session, and tracks which assumptions recur across weeks.
