So the DSCOVR satellite orbits the Earth from beyond the moon?

>You could start by looking literally anywhere in Africa, or literally any major city in the U.S.

But there's an enormous cultural, ecological, geographical, climatological, historical, and linguistic difference in just considering the population of Africa

You can't possibly think the only difference that separates the two are the races and the distance between.
There is a sense that environment can only change 'so much' and the rest is up to genes. This simply not correct; observed behavior and life outcomes are inextricably linked to factors outside of genetics; the data from research that exists currently simply doesn't establish the exact relationship between genes and the observed behavior of responses on intelligence testing.

There exist environmental factors that are hereditary as well. In the 1800s, propensity toward wearing jewelry in Europe was highly hereditary, as only women tended to engage in that behavior (thus, it had a covariance with some genetic difference (sex chromosomes). Today, it's much less hereditary as European men more commonly wear jewelry. So this is a behavior that once was heritable, and now isn't, but that certainly doesn't necessitate micro-evolution.

Intelligence is thought to be one of the most polygenic phenotypes that we can conceive of; there's too much noise in the translation between gene and phenotype that we've not yet understood.

Africans in the US today test for an average IQ of 80; well, that would simply indicate they are where whites were about a century ago. I don't think it is inconceivable that the Flynn effect can eventually eclipse all average differences if all factors could be controlled for.

Help me, /sci/.

What is one fast, easy, and cheap way one (whom is sufficiently willed to do so) can cause oneself a great deal of physical pain without risking himself any physical damage (emotional damage is OK)?

Thanks, /sci/!
