The Minnesota Trans-Racial Adoption Study is what you want. It’s basically the final word in both the “correcting for environmental bias” and “miscegenation improves offspring” claims of the kike-addled. And if you want the final word in “the education system is racist,” you want The Kansas City Desegregation Experiment. Both irrefutable.

NEVER be afraid to ask others for citations, especially if it’s for something you “read somewhere but aren’t sure if it’s legit.” We can only stop the spread of disinformation if we don’t spread it ourselves.

Tallest_Skil gave a definitive answer, but I want to chime in with two useful references. In 1966, the second edition of Elizabeth Shuey's book "The Testing of Negro intelligence" contains this statement in the foreward:

"Dr. Shuey finds that at each age level and under a variety of conditions, Negroes regularly score below whites. There is, to be sure, an overlapping of 10-15 per cent which means that some Negroes achieve high scores. But the mean differences persist and are statistically significant. We are forced to conclude that the regularity and consistency of these results strongly suggest a genetic basis for the differences. I believe that the weight of evidence (biological, historical and social) supports this judgment."

There's also "The Bell Curve", which has been written about so extensively, there's no need for me to describe it. Note that while I cause a great deal of indignation and condemnation, no one has been able to refute its conclusions.

I STRONGLY recommend getting David Duke's book, "My Awakening". It's a very interesting read, and he has an extensive list of sources for everything he says regarding race. Just those references is worth having a copy.

There's also a twin experiment I can't find, where twin Negro children were adopted by different families, one in the US and one in Canada. As they grew, the researchers found that despite the dissimilar environments, their test scores where statistically equivalent. This was notable because it took into consideration that in the communities in Canada where the adopted Negro children lived, antipathy toward Negroes was non-existent (i.e, they experience little or no "racism"). (That might have come out in the Minnesota Transracial Adoption Study. If someone can set me right on that, I'd appreciate it.)

Why do you need evidence of a study when their behavioral rhythms are proof enough?
