Pray tell. Or just tell, no praying required, that would be telling. Just prying. Required, I mean.
What age do you think it would be appropriate to start rationality training, and how would you go about it?
About 3. How old is your son again? What are you, a bad father? No worries, it may not yet be too late, if you wake him up and start now. Just ingrain the rationality training as an aspect of the way you interact with him, I go for the Socratic Method. Don't set apart "rationality training" time (or are you planning to be irrational unless rationality is scheduled?!). Helping your kid develop mental models of others is my favorite. "Why is that person doing that, what does he want to achieve with that? What else could he do? Is what he doing the best way of reaching his goals? Yea, well done, now give the ice cream man his money, he's looking at us weirdly."
(Also keep in mind the "kids do as you do, not as you say" paradigm when interacting with others in the presence of your kid. Could lead to some strange conversations with the janitor, but aren't they always. Strange, I mean.)

It really boils down to the convergence of a few factors; he's already learning a higher grade level than he'd be placed in by his age, he suffers from some hyperactivity issues, and, quite frankly, my wife and I think we can do a better job than the public system. Or at least my wife can; I'm not convinced of my abilities at a teacher yet.

If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
