The black-white average IQ gap in the USA is an established fact in psychology, and estimates of the gap range from 10 to 15 points. The existence of the gap is not the question, but the cause of the gap is the question and often debated. The cause of the gap could be either genetic variations, environmental variations (education, diet, health, etc.), or both. In your personal opinion, how much are genetic variations responsible for the U.S. black-white IQ differences? If you are unsure (and I believe everyone should be at least a little unsure), then take your best guess. The poll is anonymous.
The poll is incomplete. 0 and 100% are
not the extreme values. You have to include negative numbers (and possibly numbers above 100%) too: It's entirely possible that if it were for genetics alone, blacks would be on average a few points
more intelligent than whites but that difference overshadowed by environmental factors acting in the opposite direction. It is also
technically possible though extremely unlikely (i.e. contrary to everything we know about environments of blacks and white in the US and everything we think we know about the ways environments can influence intelligence) that the difference would be even greater if it weren't partially compensated by environmental factors.
If there were an option "
around 0%", I'd pick that. The true answer is probably somewhere between -20% and +20%. But the way things are, this is unanswerable.
Heads up, though, for putting it in Pseudoscience where it belongs straight away!
