Sorry everyone, but this doesn't pass the smell test for me. Over half of their citations are for research that's 20-40 years old, and their more contemporary citations are from papers the authors themselves published in the last ten years.
Hard agree. The test protocol is one step removed from a Scientology e-meter and the prose makes it crystal-clear that these 'researchers' are seeking to confirm their biases.
This isn't genetics. There's not much research in these areas. And a lot of it would be unrelated to the current article. There's also very little progress, if any. You really have to do better than "a smell test" based on some superficial judgement.
