Maybe black people and white people are just, well, different in some way that manifests itself, directly or indirectly, in different sleep patterns?This intransigent hatethought came after it'd been explained to him by National Journal that the apparent observation that blacks spend less of their shuteye time in slow-wave sleep than whites do is a deleterious consequence of discrimination, poverty, and poor health and certainly not due in any way to "innate biological differences" (so certain, in fact, that no data are required to explain why this certainty is so definitively certain!)
Oddly, this putative problem doesn't seem to be one blacks--who are socially encouraged to bellyache loudly about perceived problems and suffered injustices--have any self-awareness of.
In 2010 and 2014, the GSS asked respondents how often they've had trouble getting to sleep or staying asleep in the past year. The percentages among whites (n = 1,802), blacks (n = 354), and Hispanics (n = 127) who answered either "often" or "sometimes"*:
Curiously, the ordering runs in the opposite direction of what the oppression narrative would suggest. Perhaps it's the guilt weighing on whites and the clean consciences blacks enjoy that allow the latter to sleep better than the former despite the disadvantages they suffer in terms of poverty, discrimination, and loud music!
GSS variables used: SLPPRBLM(1-2)(3-4), RACECEN1(1)(2)(15-16)
* The item contains four possible responses--often, sometimes, rarely, never. If we just look at "often", we get 23.1% for whites, 15.8% for blacks, and 19.1% for Hispanics. If we go the other direction and look at "never" responses, we get 17.0% for whites, 21.9% for blacks, and 21.9% for Hispanics. No matter how it is sliced, blacks report significantly less trouble sleeping well than whites do.
