Thanks for the link, but that's not what it says: "
According a study dating back to 2010, there were at least three times as many psychopaths in executive or CEO roles than in the overall population. But more recent data found it’s now a much higher figure: 20 percent."
Saying "common" is as useless as saying "many". It means less than saying "most", which at least indicates a relative majority...and they don't even make that cut with 3%-20%. Also, the link says "20 percent", but the actual study linked study says "
between 3% and 21%".
That said, sociopathy is not just a mental disorder, but also a range like any other disease or disorder; one that can range from functional to dysfunctional. Trump's actions last night, along with multiple reports of those who have worked with him, indicate he is largely dysfunctional.

"
Mr Brooks says emerging studies show while one in 100 people in the general community and one in five people in the prison system are considered psychopathic, these traits are common in the upper echelons of the corporate world, with a prevalence of between 3% and 21%."

The psychopath has had and continues to have a grossly disproportionate impact at virtually every point in the criminal justice system. Though psychopaths make up roughly 1% of the general male adult population, they make up between 15% and 25% of the males incarcerated in North American prison systems.100 That is, psychopaths are 15 to 25 times more likely to commit crimes that land them in prison than non-psychopaths. There is no other variable that is more highly correlated to being in prison than psychopathy. Substance abuse, for example, on which our corrections systems have spent untold trillions, is a distant second. Although between 65% and 85% of people in prison have or had substance abuse problems, 8% of the U.S. population at large suffers from substance abuse.101 Thus, having a substance abuse problem makes it only around nine times more likely that a person will be in prison, compared to psychopathy’s correlation of between 15 and 25 times more likely.
