Digits Backward and the Mercer-Kamin Law

An Empirical Response to Mercer’s Treatment of Internal Validity of IQ Tests
  • Robert A. Gordon
Part of the Perspectives on Individual Differences book series (PIDF)

Abstract

Jensen (e.g., 1980a) has grouped the various criteria for detecting bias in ability tests under two broad headings: internal and external. Studies under the first heading concern themselves with relations among the components of a test; those under the second are concerned with predictive relations between the test as a whole and outside variables. Mercer organized her chapter in this book to parallel Jensen’s distinction, and my chapter parallels hers, but, because of space limitations, only the half of her chapter concerned with internal validity.
