They talk about these things in the article. Somebody did a study on retirees, and 20,000 of them gave DNA samples as well. They used the DNA samples and did a broad test (i.e. not 1 gene but 1,000,000) and were able to correlate the genetic test at a significant level with educational attainment. The article says it explains 11% of the difference. It also mentions that it only explains these things for white people because most gene tests are on white people and attempting to correlate things in other ways can come up with bizarre findings. The test has reportedly been independently verified.
