The current research examines the utility of the evil woman hypothesis by examining sentencing discrepancies between male and female sex offenders. National Corrections Reporting Program data are used to identify sex offenders for the years 1994 to 2004 and the sentences they received for specific sex offenses. Statistical analyses reveal a significant difference in sentence length between men and women, but not in the expected direction. The evil woman hypothesis would assume women are sentenced more harshly, but data show men receive longer sentences for sex offenses than women. Support is provided for the chivalry hypothesis to explain immediate sentencing disparity.
