Wilson reflects on the nearly eight hundred research studies that claim to provide an empirical test of the arguments presented in his book The Declining Significance of Race (1978; second edition, 1980). Wilson considers representative studies that incorrectly address his book, before discussing those publications that correctly address his thesis, including those that uphold, partially support, or challenge his arguments and basic claims. In the process, Wilson explores how some of these studies led him to revise or extend parts of his basic thesis, especially as it pertains to race and interracial relations today. Wilson also takes into account changes within the African American population since he wrote The Declining Significance of Race . He reveals how his thoughts have changed with respect to both race- and class-based solutions for the problems faced by people of color.
