More than the facts. An answer carries their exact words, what they repeat, where the emotion is, the questions they ask back, what they avoid, where their energy changes, and the signals that they're buying. Listening in this system is an inventory discipline — a list of things to actively collect, not a polite silence while you wait to talk.
The short answer
How it runs
Every item on the list has a later use: exact words get said back, repetitions become the presentation's emphasis, their questions become your porcupine returns, avoidance becomes tomorrow's surfaced concern. Listening that doesn't get spent was just hearing. The reps who “have a great feel for people” are usually running this inventory without knowing its name — the system's contribution is making it a checklist you can practice until it's reflex.
