Core Idea

Not all hypotheses are equally important. The most dangerous assumptions should be tested first.

Prioritisation Framework

Hypotheses are ranked using:

• Criticality
• Existing evidence

High-Risk Assumptions

The highest priority assumptions are:

• Critical to success
• Supported by little or no evidence

Four Risk Categories

• Desirability
• Feasibility
• Viability
• Adaptability

Key Insight

Testing low-risk assumptions first creates false progress.
