Have you seen that John le Carre book about the Israeli secret service's assassination squad? Well, I think Bradley Burston is trying so hard to play one of the lead characters in that homage to righteous sadism (or whatever le Carre thought he was trying to accomplish) that he is starting to grin at himself. That may be the "straight-faced test" in operation. If so, it may put my theory of that test to the test. My theory is that this self-parody and stifled nervous giggling is not simply the result of cognitive dissonance or similar autonomous feelings of implausibility, but rather the response to a calm stare, at such a time and place where that stare is more eloquent and persuasive than any gesture, no matter how clever or violent.
