This article is a collection of 25 key facts about intelligence, it's heritability, the differing cognitive abilities of various ethnic groups, as well as the effects high or low intelligence might have on one's life.

With the controversy that resulted from the publication of, "The Bell Curve: Intelligence and Class Structure in American Life" both critics and defenders of the book began writing articles either in defense or in favor of many of it's conclusions.

The entire 25-point piece is signed by 52 specialists in the field of intelligence research.
