(2013) conducted a study to determine if the various personality disorder clusters—Type A (Schizoid, Odd), Type B (Narcissistic, Anti-social) and Type C (Avoidant, OCD)—were solely detrimental in terms of life outcomes for the individuals with these personality disorders (PDs), or if they instead presented their sufferers with various potentially adaptive benefits, such as more plentiful sexual and social opportunities. | ||

A further questionnaire designed to broadly measure various life outcomes such as number of sexual partners, employment, income, and health was also administered. | ||
A multiple linear regression performed by the researchers on the data was used by the authors to estimate the contribution of the PD scores to various life outcomes. | A multiple linear regression performed by the researchers on the data was used by the authors to estimate the contribution of the PD scores to various life outcomes. | ||

Namely, those individuals high in type-B personality cluster traits (Narcissism, Anti-Social, Borderline, Histrionic) of both sexes | Namely, those individuals high in type-B personality cluster traits (Narcissism, Anti-Social, Borderline, Histrionic) of both sexes have 3.5x as many sexual partners as low B subjects, with five times as many short-term mates and twice as many long term mates. The researchers also found that those higher in cluster B had 39% more children than those lower in cluster B traits. | ||

It can be surmised that these personality traits, with all their concomitant adverse outcomes, both for the bearers of these disorders and their potential victims, are most likely being significantly sexually selected for in various modern societies. | |||
