By telling so many lies, & so many that are mean-spirited, Trump is violating some of the most
fundamental norms of human social interaction and deceny. Many of the rest of us, in turn, have abandoned a norm of our own - we no longer give Trump the benefit of the doubt that we usually give so readily. - Bella DePaulo
Excellent overlooked opinion piece from last month's (12/10/2018) Washington Post
I study liars. Ive never seen one like President Trump.
The college students in our research told an average of two lies a day, and the community members told one. A more recent study of the lies 1,000 U. S. adults told in the previous 24 hours found that people told an average of 1.65 lies per day; the authors noted that 60 percent of the participants said they told no lies at all, while the top 5 percent of liars told nearly half of all the falsehoods in the study.
In Trumps first 298 days in office, however, he made 1,628 false or misleading claims or flip-flops, by The Posts tally. Thats about six per day, far higher than the average rate in our studies. And of course, reporters have access to only a subset of Trumps false statements the ones he makes publicly so unless he never stretches the truth in private, his actual rate of lying is almost certainly higher.
That rate has been accelerating. Starting in early October, The Posts tracking showed that Trump told a remarkable nine lies a day, outpacing even the biggest liars in our research.
But the flood of deceit isnt the most surprising finding about Trump.
