It's one sided because one side is right and the other side is wrong. Studies showing "innate" differences (whatever "innate" means) are dismissed on methodolgy grounds because they do have methodology flaws. The overwhelming majority of population geneticists and evolutionary biologists dissmiss race science because it is flawed and has been repeatedly shown to be flawed since the 1920s. Techy people seem to trust the scientific consensus for plenty of issues, I don't see why suddenly an argument about "being fair to both sides" should be made just when it comes to the IQ of black people.
