I agree that being smart doesn't magically give you extra time (although maybe watching less TV goes here).

What I said was that you assumed everyone was the average for their group and didn't account for variation: you discount everyone who's employed/has kids, rather than instead looking at what percentage of those groups spend >30 minutes/day on the computer.

ALSO - ( :P ) I still think that's too strict. You don't even accept the full number of people who declared "none" for religion, apparently (15% in 2008 - see your link pg 5). You claim that if you believe in god then "lessons in rationality are a complete waste of time for you," when I'd think that it would be the opposite: it is when someone is irrational that they can use lessons in rationality. The question is then not "who already agrees?" but "who is willing to listen?"
