Somehow I imagine that Nick means to say there are costly signals in this game 
— that motor action is thicker than conversation or reflection.

If I am walking across a snowfield that I know to be filled with crevasses, and 
I know I can’t tell which snow holds weight and which doesn’t, my movement is 
really different than it is putting my feet on the floor beside the bed in the 
morning.

To take a different example that is counterfactual but easier to use in 
invoking the real physiological paralysis, if Thank God Ledge on halfdome were 
not actually a solid ledge, but a fragile bridge, or if there had been a 
rockfall that left part of it missing and I were blindfolded, or if I were a 
prisoner of pirates blindfolded and made to walk the plank, my steps would land 
differently than they do when I get out of bed in the morning.

There I didn’t say what anyone else would do in any circumstance, but did claim 
that my own motions have different regimes that are viscerally _very_ distinct. 
 I’m not sure I can think about whether I would fight for air when being 
drowned.  It might be atavistic and beyond anything I normally refer to as 
“thought”.  I certainly have had people claim to me that that is the case.

Those distinctions may occupy a different plane than the distinction between 
reasonableness and dogmatism all in the world of conversation and the social 
exchange.

But I should not speak for others.  Only for myself as a spectator.
