Donald Trump is a notorious liar. In fact, lies more often than he tells the truth, at least in public. Many, many of his boldest lies are in the form of Tweets, most recently about Amazon and the Post Office. But prevarication does not stop at the top. Sarah Huckabee Sanders (and he predecessors and minions) are forced to lie at the podium for the President - or at least repeat his lies. Many, if not most, of his Cabinet Secretaries have been caught out in whoppers - Tom Price, Jeff Sessions, and Scott Pruitt most spectacularly, but Betsy DeVoss, Ben Carson... - and often under oath.

Indeed, it appears to be a standard practice of both the White House and many, many appointees and nominees. It is so pervasive, that they do it on big things and little things. Pruitt lied about using private e-mail to conduct government business; DeVoss claimed she was not part of he family's foundation, although she was listed as an officer for 17 years, not to mention all of the falsehoods she's uttered about education. Pruitt's prevarications are legendary, although they don't rival Trump's.

All of these lies take a toll: Trump’s Lies vs. Your Brain - Politico Magazine.
Our brains are particularly ill-equipped to deal with lies when they come not singly but in a constant stream, and Trump, we know, lies constantly, about matters as serious as the election results and as trivial as the tiles at Mar-a-Lago. (According to his butler, Anthony Senecal, Trump once said the tiles in a nursery at the West Palm Beach club had been made by Walt Disney himself; when Senecal protested, Trump had a single response: “Who cares?”) When we are overwhelmed with false, or potentially false, statements, our brains pretty quickly become so overworked that we stop trying to sift through everything. It’s called cognitive load—our limited cognitive resources are overburdened. It doesn’t matter how implausible the statements are; throw out enough of them, and people will inevitably absorb some. Eventually, without quite realizing it, our brains just give up trying to figure out what is true.

This was the methodology employed by Russia in the 2016 campaign, but it is also employed by Trump (and his minions) on a constant basis, making it difficult to differentiate which disinformation campaign is at play. I think the only way to combat this effort is to confront it openly and make it have a cost. How to do so, I have not yet fully determined, but the goal should be to return honesty as a community value and make it have meaning.
A well reasoned argument is like a diamond: impervious to corruption and crystal clear - and infinitely rarer.

Here, as elsewhere, people are outraged at what feels like a rigged game -- an economy that won't respond, a democracy that won't listen, and a financial sector that holds all the cards. - Robert Reich
