Good liars are skilled at reading others well, putting them at ease, managing their own emotions, and intuitively sensing how others perceive them.

Liars do look you in the eye. They do not always stutter, stammer, blush or fidget.

For the liespotter who knows how to listen well, the random words, sounds, and phrases in a person's speech are never as random as they seem. They offer a clear sightline into the liar's psyche.

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

Pay attention to science and not myths: We think liars won't look you in the eyes, but it turns out an honest person will only look you in the eyes about 60 percent of the time.

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.
