Summary

Many experts in genetics and psychology have raised doubts about how strong the evidence really is when it comes to linking genes to things like intelligence, personality, or mental health problems. Some studies do suggest genetic connections, but the results are often inconsistent, hard to repeat, and affected by problems like sample differences, weak effects, and other known issues. Because of this, many researchers now think there’s no solid proof that genetics play a big role in the kinds of traits and issues discussed on this website. There are already plenty of detailed critiques online, so I won’t go over them here, but it’s important to know that even many experts question the results of genetic studies that are often used to argue against ideas like mine.
