1) Our new genome-wide association study for IQ (https://www.nature.com/articles/s41467-018-04362-x …) included the peripheral result that some genes linked to higher IQ are also linked to higher likelihood of poor eyesight. Here's how the media bollocksed up the coverage of it in almost every way:

What are these "race differences"?
-
Myopia is extremely common in East Asians, rate are low in blacks, very low in Australian aborigines.
-
I thought myopia was thought to be mostly associated with lack of sunlight. So less race differences than societal ones.
-
Probably not - if so, I would have had to be brought up in a cave. Genetics matters, environment too I think.

Here's an article about it, if you're interested -https://www.nature.com/news/the-myopia-boom-1.17120 …

It’s possible for a trait to be influenced by an environmental factor while showing a genetically determined degree of response to that factor.
-
Yes I know. Environmental differences seem to have the greater influence on myopia, going by recent research.
-
And it’s also possible for a trait to be “racial” while being more strongly influenced by environment than by genetics (as long as it has a genetic component).
