CORE DEFINITION

When the pulse (internal data) and symptoms (external manifestations) are logically contradictory (e.g., a deep, thin pulse suggesting cold deficiency, but symptoms of high fever and thirst), if the pulse is judged to be misleading, ignore the pulse and treat based on symptoms. Scaffold role: anti-interference protocol. What to do when data conflict? There must be a 'ruling rule'. When the system is in an extreme state (e.g., true heat with false cold), the sensor (pulse) may malfunction. At this time, trust the visible facts (symptoms) to avoid being misled by false information.

Anti-interference protocol. What to do when data conflict? There must be a 'ruling rule'. When the system is in an extreme state (e.g., true heat with false cold), the sensor (pulse) may malfunction. At this time, trust the visible facts (symptoms) to avoid being misled by false information.

Anchor fast decisions

In TCM syndrome differentiation, the pulse (internal reference) and symptoms (external manifestation) may diverge due to 'true/false cold-heat' making one of them false. Discarding pulse to follow symptoms means when the pulse is judged to be false (e.g., in true heat with false cold, the pulse is repelled and appears deep and thin), then use the more intuitive and reliable symptoms as the basis for decision. Essentially, it is a 'priority ruling rule when multi-source signals conflict'.

MINIMUM ACTION

In progress 0/1

Practice this model in one real situation:

Collect both pulse and symptom signals and compare for consistency. 2. Analyze which side might be false (considering medical history and overall condition). 3. If the pulse is false, discard it and establish treatment based on symptoms (e.g., clearing heat). 4. After treatment, recheck whether pulse and symptoms converge. 5. In management/engineering analogy: when internal metrics conflict with external facts and there is reason to suspect the metrics are malfunctioning, trust the facts.
