>I think you may be having a selection bias here: there is a lot of people who sleep 8-9 hours at night who are in high income brackets (I think that’s what you mean by “successful”, even though that’s a debatable metric).

I'd disagree. Numerous studies with large sample sizes show the average sleep in America is 6 hours and change. I'd need to see some hard evidence that there are "a lot" of people, that is, a statistically significant number of high-earners, who sleep 8-9 hours.

In fact, there is evidence to the contrary of your claim:

>Turns out, the difference is pretty negligible — the "successful" people get 12 minutes less than the average American. According to this 2013 Gallup poll, the average American gets 6.8 hours of sleep every night.

This may sound like pedantry, but I would call 6.8 "almost seven hours" not "6 hours and change".

I track my sleep as best I can, and nearly-seven is sustainable, while a bit more than six on a consistent basis leaves me feeling pretty wrung out.

The extra 45 minutes we're talking about here are likely to be mostly REM, given how intensely I dream when I start napping to make up a deficit.
