What is the difference between analytic and intuitive judgments in this skill?

Analytic judgments are derived directly from evidence and logic, while intuitive judgments are informed calls that go beyond what the available data strictly supports.

Does this skill require previous analysis steps?

Yes, this is Step 5 of the HEAD process. It is most effective when used after Step 4 (Evaluate) to challenge the assessment already established in the conversation.

What is the HEAD framework used for in Claude Code?

The HEAD framework is an intelligence analysis methodology used to ensure rigorous thinking, data evaluation, and objective decision-making during complex tasks.

How does the bias audit identify risks?

It evaluates the current analysis against six specific cognitive biases—Availability, Confirmation, Anchoring, Halo Effect, Mirror Imaging, and Groupthink—and assigns a risk level to each.

Productivity & Workflow

Implements Step 5 of the HEAD framework to stress-test analysis through bias audits, gap identification, and alternative hypotheses.

The HEAD Analysis: Challenge Assumptions skill applies Philip Mudd’s intellectual discipline framework to evaluate the rigor of any assessment. It forces a structured bias audit, identifies critical unknowns and their potential implications, and proposes alternative hypotheses to counter cognitive blind spots. By explicitly distinguishing between analytic evidence and intuitive judgment calls, this skill ensures that decision-making is based on robust, well-vetted logic rather than surface-level assumptions or hidden biases.
