[ODP] The Elusive X-Factor: A Critique of J. M. Kaplan’s Model of Race and IQ

Title: The Elusive X-Factor: A Critique of J. M. Kaplan’s Model of Race and IQ

Author: Dalliard

Abstract: Jonathan Michael Kaplan recently published a challenge to the hereditarian account of the IQ gap between whites and blacks in the United States (Kaplan, 2014). He argues that racism and “racialized environments” constitute race-specific “X-factors” that could plausibly cause the gap, using simulations to support this contention. I show that Kaplan’s model suffers from vagueness and implausibilities that render it an unpromising approach to explaining the gap, while his simulations are misspecified and provide no support for his model. I describe the proper methodology for testing for X-factors, and conclude that Kaplan’s X-factors would almost certainly already have been discovered if they did in fact exist. I also argue that the hereditarian position is well-supported, and, importantly, is amenable to a definitive empirical test.

Keywords: IQ, g factor, race, racism, measurement invariance
