Pyrrhonism, you start on the assumption that no-one [else] even exists and go from there ... ;o)

Seriously, I'm not so sure -- I try to trust first and then update that status as more information becomes available; but that's more of a religious position.

I don't think it's necessarily instructive to look at my personal modes here. I guess my main point is that if you're going to say "well humans have cracked trust, we'll just model it on that" then I think you're shooting wide of the mark.
