Sometimes we fear and fight reality. If the Bell Curve has information / facts that upsets your worldview don't be so fearfull. Embrace new ideas and change your worldview. You can run but you can't hide from the truth.
Murray's ideas aren't "new". Not even a little. And they aren't "truth".
Your local university can do it if you really care. A ton of material has been written about Murray's work. Taboo? Humanity has been using science to break the backs of minorities for centuries. People aren't hiding the corner quivering and afraid to touch Murray's work.
I attended grad school with people who studied sociology and history, who were able to synthesize the state of the fields for me. I'm married to a professor and good friends with other professors who study topics in this space. None of them have good things to say about Murray's work.
