In this article, the author explains that on top of body language, some language cues can also detect a liar. It mentioned things like liars trying not using first person pronouns and increased use of negative statements that could be subconsciously mirroring the negative emotions a liar may feel such as fear or guilt.

Parents teach their children to lie. The teaching process is subtle but just as effective as if they had sent their children to formal classes in deception. How many times have parents told their kids "Look me in the eye and then tell me what you did?"

Research demonstrates that liars maintain more deliberate eye contact than do truthful people.

Contrary to popular belief, liars don't actually give many visual giveaways to their lies. The better cues are in their speech. The common misconceptions about liars and their body language are actually signs of anxiety. More often than not, truth-tellers are assumed to be liars because they are anxious to recount the correct details

This New York Post article discusses strategies to tell when someone is lying. It provides tips on how to detect a liar, like what details they won't be able to provide. It also discusses a study conducted by the University of Amsterdam. This study describes nine experiments where 1,445 people needed to determine whether handwritten letters, videos, and interviews, both pre-recorded and live, were discussing true or false information. It also discusses the accuracy of polygraphs and how our intuition and attention to detail can help us determine if someone is being truthful or not.

"A small band of linguists, engineers and computer scientists, among others, are busy training computers to recognize hallmarks of what they call emotional speech - talk that reflects deception, anger, friendliness and even flirtation. ... Algorithms developed by Dr. Hirschberg and colleagues have been able to spot a liar 70 percent of the time in test situations, while people confronted with the same evidence had only 57 percent accuracy ... His lab has also found ways to use vocal cues to spot inebriation, though it hasn't yet had luck in making its computers detect humor - a hard task for the machines, he said."

Lying in politics transcends political party and era. It is, in some ways, an inherent part of the profession of politicking. But Donald Trump is in a different category. The sheer frequency, spontaneity and seeming irrelevance of his lies have no precedent. A whopping 70 percent of Trump's statements that PolitiFact checked during the campaign were false, while only 4 percent were completely true, and 11 percent mostly true. (Compare that to the politician Trump dubbed "crooked," Hillary Clinton: Just 26 percent of her statements were deemed false.) For decades, researchers have been wrestling with the nature of falsehood: How does it arise? How does it affect our brains? Can we choose to combat it? The answers aren't encouraging for those who worry about the national impact of a reign of untruth over the next four, or eight, years. Lies are exhausting to fight, pernicious in their effects and, perhaps worst of all, almost impossible to correct if their content resonates strongly enough with people's sense of themselves, which Trump's clearly do.

This article discusses the language of lying. It talks about liars' tendencies and patterns. Lying is very complex, but language itself is very good lie-detector.
