An academic look at Trump's lies

Bella DePaulo, Chicago Tribune -I spent the first two decades of my career as a social scientist studying liars and their lies. I thought I had developed a sense of what to expect from them. Then along came President Donald Trump. His lies are both more frequent and more malicious than ordinary people's.....

At The Washington Post, the Fact Checker feature has been tracking every false and misleading claim and flip-flop made by Trump this year.... I categorized the most recent 400  lies that The Post had documented through mid-November in the same way my colleagues and I had categorized the lies of the participants in our study.

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.) The most prolific liar among the students told an average of 6.6 lies a day. The biggest liar in the community sample told 4.3 lies in an average day.

In Trump's first 298 days in office, however, he made 1,628 false or misleading claims or flip-flops, by The Post's tally. That's about six per day, far higher than the average rate in our studies. And of course, reporters have access to only a subset of Trump's 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 Post's tracking showed that Trump told a remarkable nine lies a day, outpacing even the biggest liars in our research.

... My colleagues and I found it easy to code each of our participants' lies into just one category. This was not the case for Trump. Close to a quarter of his false statements (24 percent) served several purposes simultaneously.

Nearly two-thirds of Trump's lies (65 percent) were self-serving. Examples included: "They're big tax cuts — the biggest cuts in the history of our country, actually" and, about the people who came to see him on a presidential visit to Vietnam last month: "They were really lined up in the streets by the tens of thousands."

Slightly less than 10 percent of Trump's lies were kind ones, told to advantage, flatter or protect someone else. An example was his statement on Twitter that "it is a 'miracle' how fast the Las Vegas Metropolitan Police were able to find the demented shooter and stop him from even more killing!" In the broadest sense, it is possible to interpret every lie as ultimately self-serving, but I tried to stick to how statements appeared on the surface.

Trump told 6.6 times as many self-serving lies as kind ones. That's a much higher ratio than we found for our study participants, who told about double the number of self-centered lies compared with kind ones.

The most stunning way Trump's lies differed from our participants', though, was in their cruelty. An astonishing 50 percent of Trump's lies were hurtful or disparaging. For example, he proclaimed that John Brennan, James Clapper and James Comey, all career intelligence or law enforcement officials, were "political hacks." He said that "the Sloppy Michael Moore Show on Broadway was a TOTAL BOMB and was forced to close." He insisted that other "countries, they don't put their finest in the lottery system. They put people probably in many cases that they don't want." And he claimed that "Ralph Northam, who is running for Governor of Virginia, is fighting for the violent MS-13 killer gangs & sanctuary cities."
