CORE DEFINITION

The patient spends the entire consultation discussing trivial ailments, only to suddenly reveal the real, major problem (e.g., "Doctor, actually I've had chest pain for a long time") at the moment they are about to leave, hand on the doorknob.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Capture the final information. In interviews, negotiations, or dates, do not relax just because it seems to be over. The other party often reveals the most genuine and core information during the 'goodbye moment' when their defenses are weakest.

anchor

Anchor fast decisions

The client only brings up the hardest, most critical topic when the session is about to end and they have their hand on the doorknob to leave, due to a need for safety or procrastination.
