and their validity. What do they mean? This has turned out to be a

Herrnstein and Murray about—called The Bell Curve. And in The Bell Curve
these authors made the argument that IQ matters immensely for everyday
life and that people’s status in society? How rich they are and how
successful they are? Follow their IQ as measured in standard IQ tests.
Now, this book made a lot of claims and it’s probably before many of

controversy some interesting papers came out.
