Request that you refer to a specific study and give evidence that Rushton's study is wrong. These constant attempts to shout that the data and rails are also wrong are really tiring. You can write a lot about a professor, but science is about doing experiments. The fact that someone did a different experiment, on a different topic, and came out with different conclusions is irrelevant, this finding cites these studies and not others so please refer to them and not cite a study on a different topic.
