They Will Never Get A Reaction Out Of You Again

In 1993, researchers at the University of Trier found what most people get backwards: a calm, non-reacting face doesn't defuse a room — it floods the other person's body with one of the most reliable stress surges ever measured in a lab. Anyone who can get to you is running a quiet prediction about how you'll react, and your reaction is the data that funds it. There are seven exact places your body leaks that proof. Seal all seven, and their model comes apart instead of you.
