 Similarly, the authors conclude that women are less likely to be exposed to opportunities for criminal behavior, speculating that "constraints often placed on females, and that accompany their lifestyles" contribute to less opportunity for crime.With self-control being significant for males but not for females, the conclusions of this study pointed toward the notion that men and women commit crimes for different reasons.The notion that self-control was only significant for women when combined with opportunity helps account for the gender gap seen in crime rates.
