The Dark Triad of personality and folk intuitions about free will and moral responsibility

G*Power (Erdfelder, Faul, & Buchner, 1996) was designed as a general stand-alone power analysis program for statistical tests commonly used in social and behavioral research. G*Power 3 is a major extension of, and improvement over, the previous versions. It runs on widely used computer platforms (i.e., Windows XP, Windows Vista, and Mac OS X 10.4) and covers many different statistical tests of the t, F, and chi2 test families. In addition, it includes power analyses for z tests and some exact tests. G*Power 3 provides improved effect size calculators and graphic options, supports both distribution-based and design-based input modes, and offers all types of power analyses in which users might be interested. Like its predecessors, G*Power 3 is free. Show more

Research on moral judgment has been dominated by rationalist models, in which moral judgment is thought to be caused by moral reasoning. The author gives 4 reasons for considering the hypothesis that moral reasoning does not cause moral judgment; rather, moral reasoning is usually a post hoc construction, generated after a judgment has been reached. The social intuitionist model is presented as an alternative to rationalist models. The model is a social model in that it deemphasizes the private reasoning done by individuals and emphasizes instead the importance of social and cultural influences. The model is an intuitionist model in that it states that moral judgment is generally the result of quick, automatic evaluations (intuitions). The model is more consistent that rationalist models with recent findings in social, cultural, evolutionary, and biological psychology, as well as in anthropology and primatology. Show more

Three socially aversive traits-Machiavellianism, narcissism, and psychopathy-have been studied as an overlapping constellation known as the Dark Triad. Here, we develop and validate the Short Dark Triad (SD3), a brief proxy measure. Four studies (total N = 1,063) examined the structure, reliability, and validity of the subscales in both community and student samples. In Studies 1 and 2, structural analyses yielded three factors with the final 27 items loading appropriately on their respective factors. Study 3 confirmed that the resulting SD3 subscales map well onto the longer standard measures. Study 4 validated the SD3 subscales against informant ratings. Together, these studies indicate that the SD3 provides efficient, reliable, and valid measures of the Dark Triad of personalities. Show more
