A narcissist like Trump must constantly inflate and exaggerate in order to keep the supply trains running. He has to brag about how, 'I have a very high IQ' or concoct stories about people agreeing with him.

Maybe Trump isn't a racist in private. But he's sure acting like one in public. And his body language is corroborating the evidence.

Honest people remember stories in the order of emotional prominence, but liars will recount a story in chronological order. Memory rarely works that way.

Trump is a master obfuscator. Like an octopus escaping a predator, he releases a cloud of ink when called to the carpet on one of his many lies. His strategy? Obfuscate, then reference others. 'Millions agree,' 'everyone knows,' 'many have done it.'

Research indicates that a pause tends to be a signal that a cluster of deceptive cues is on its way. This is a key reason why voters routinely associate Trump with authenticity: He rarely pauses.

One immutable trait of the gullible is that they are credulous to a fault. Though no-doubt well-meaning, the naive are Trump's base.
