It sounds like the words “sleep deprivation” are doing a lot of work in the original post. You don’t mean “sleeping much less than the average”, but literally “depriving yourself of sleep you need”?
I tried to be explicit about the average number of hours slept in the studies included in these meta-analyses of experimental studies. Usually, it’s about 4 to 5 hours, with the average seeming to be closer to 4. I also tried to be explicit about how many hours of sleep per night my claims refer to in my conclusion (except for the first claim, which I specified was about “shorter-than-average” sleep, and the last one, which is a harder-to-operationalize claim, but still didn’t explicitly refer to “sleep deprivation”).
if sleep scientists have the concept of standard deviation in their models I’ll be impressed.
Standard deviations are used very often; I would be surprised if they weren’t used in 5% or more of the sleep studies I’ve read.
Sorry yes, of course they’re including SD calculations in their papers. What I meant was that medical papers (or popular coverage thereof) almost never consider the implications of the fact that 0.3% of people will be >=3 standard devs out, and with a large enough population that’s a lot of people.
