The answer is simple: if he wanted to prevent autonomic nervous system-derived tells, he should have taken a beta blocker. Beta-adregenic blockers such as propranolol totally prevent the body from feeling the effects of adrenaline and norepinephrine. In other words, when your amygdala is short-circuited by beta blockers, you couldn't have a "fight or flight" response even if you wanted to.

I once did an psychological experiment involving completing logic puzzles while being intermittently administered mild electric shocks while on propranalol. I could think 100% rationally and complete problem-solving tasks, but not being the least bit afraid of anticipating a shock was the most extraordinary feeling. I never realized how much I thrive on adrenaline and nervous energy until it was gone.

In sum, I have no ethical problems whatsoever with detecting involuntary tells--or the chemical suppression thereof. [img]/images/graemlins/smile.gif[/img]
