The Diary Of A CEO
Traits Exist on a Spectrum 0:00
Sadism, narcissism, Machiavellianism, and psychopathy are not simple yes or no categories. They exist on a continuum, so how many people count as high depends entirely on where you draw the cutoff line.
Clinical Cutoffs Are Rare 0:00
At true clinical extremes, psychopathy affects about one percent of people, based on scoring thirty out of forty on a standard checklist, while narcissistic personality disorder affects two to five percent.
Self-Report Estimates Are Higher 0:32
There are no clinical cutoffs for sadism or Machiavellianism, so researchers rely on self-report surveys instead. Looking at people who agree with statements like being a born leader or enjoying seeing others hurt, about ten percent of the population scores high on these traits.
