“On average, men are more unrestricted and show higher-risk and sensation seeking; they are also lower in agreeableness, honesty-humility, and disgust sensitivity, particularly in the sexual domain (in constrast, there are only minor sex differences in impulsivity and conscientiousness). The reason is that these traits are crucially involved in the mating-parenting tradeoff, and males tend to invest in mating effort more than females even net of individual differences in life history strategies.”
