Most flawed arguments do not collapse because the logic is exotic. They collapse because an unstated assumption was smuggled in and never inspected. Assumption Audit trains you to look for that hidden hinge.
This skill transfers far beyond formal argument. Product bets, hiring calls, diagnoses, financial theses, and interpersonal judgments all ride on assumptions that often remain implicit. Surfacing them early is one of the highest-leverage cognitive habits in the product.

Identifying the unstated assumption that an argument, forecast, or recommendation quietly depends on.

Stress-test the structure
Feedback shows how the whole argument changes if that assumption fails.
