 Which wouldn't the author use to describe Herrnstein and Murray?
The Bell Curve Flattened Charles Murray is a publicity genius, and the publication of his and Richard Herrnstein's book, The Bell Curve: Intelligence and Class Structure in American Life , in the fall of 1994 was his masterpiece. Another handpicked group was flown to Washington at the expense of the American Enterprise Institute and given a weekend-long personal briefing on the book's contents by Murray himself (Herrnstein had died very recently), just before publication. Herrnstein and Murray didn't do this, so it wasn't until a full year or more after The Bell Curve was published that the leading experts on its subject had a chance to go through the underlying data with care.
