Hale: Blacks more likely to have short sleep vs whites, even controlling for SES factors. #HBA2017
Sleeping behavior is IQ related. Try controlling for that confound. Can be done with OKCupid data.

Could it be the reverse? (IQ is sleeping behavior related?) Is the association b/n sleep and IQ correlation or causation?
-
IQ is very stable, so it's not reverse causation. But could be confounded. I don't know.
-
Stable across lifetime? Stable across populations? Can you clarify a bit further what you mean by "IQ is very stable"?
-
I meant life time.
-
Can you tell us more? How might IQ and sleep be interrelated? How might that be associated with race? Do you have any references to share?
