FAITH... WITH REASON

The "fine-tuned skill" is nothing but "getting better at approximating probabilities and keeping track of tendencies." Bluffing involves the same probabilities, and "reading" is basically useless online, and less useful offline than most think. It's not like Hollywood where the key to winning is noticing people's tells. The real game is much subtler and more technical; but it's tough to make drama out of people doing advanced mental algebra and probability calculations. 

Correct, and that was my entire point. You said that faith is about acting on something you have "complete trust and confidence in." My dice example was a way of showing that you can act based on an analysis of the risk/reward, and you can do that in a way where faith isn't involved at all. I think most of the examples you've offered in this thread are the same. In each case, the person just decides the risk is worth the reward; they don't necessarily have complete trust and confidence that something bad won't happen (the trapeze artist won't fall, the guy won't juggle the chainsaws, the bridge won't break, etc.). Even though in your examples the person has more confidence than in my example with the die roll the general point still stands. 

Right, so, again, you can act on things where an outcome isn't certain without having faith. You driving a car while acknowledging the risk is the same as a person crossing a rickety bridge while acknowledging the risk, or taking your kid to see a trapeze artist while acknowledging the risk, etc. So how would you describe the difference between you driving a car knowing that an accident is possible and you having faith that in driving the car? 

It seems to me that if you're having doubts then you don't have "complete trust and confidence," since the entire idea of "complete trust" would seem to be "trust without doubts," or else what does the "complete" refer to? If you have doubts, but also faith, this would seem to be more inline with my definitions of faith essentially being belief beyond where the evidence leads.
