Arthur C. Brooks discusses the phenomenon of the “Dark Triad” personality in his article. This term, established by psychologists Delroy Paulhus and Kevin Williams in 2002, refers to individuals exhibiting three distinct traits: narcissism, Machiavellianism, and a certain level of psychopathy. These individuals often display a pattern of charming behavior initially, only to later reveal manipulative and harmful tendencies, leaving those they interact with hurt and baffled.
