When the studies on personality are examined, it is seen that most of them are examined with the bright side of personality. However, in 2002, after Paulhus and Williams used the concept of dark personality traits (Paulhus and Williams, 2002: 557) to describe the malevolent side of human nature, scientists began to investigate the dark side of personality.
When the literature is examined, it is seen that narcissism, machiavellianism and psychopathy are called the "dark triad". Dark triad personality traits seem to be effective on individual behavior. This effect is negative in terms of individual, organizational and social aspects. Necessary strategies must be developed to prevent or reduce this negative effect. From this point of view, it is seen that the concept of "dark triad" has attracted attention in the literature and various studies have been done.
The three personality traits, narcissism, machiavellianism and psychopathy, which are discussed under the title of the Dark Triad, are defined within the framework of previous studies, and studies in the field are summarized in terms of their similarities and differences.
