Nearly everyone engages in manipulation and exaggeration of the things they have seen, heard, and experienced, or simply tries to pull a fast one on someone every now and then. But even when deceivers think of detailed plans and go over the smallest details a thousand times, one slip and the deceit is out in the open. After all, if you’re going to lie, you should be very good at it. Otherwise, get comfortable with being mercilessly teased by anyone who found out about your little mishap.

To learn more about the field of deception, we reached out to Aldert Vrij, a professor of Social Psychology at the University of Portsmouth, UK, and the author of Detecting Lies and Deceit: Pitfalls and Opportunities. He explained that people sometimes make things up because they are too confident they can get away with it. "Also, people often lie to cover up wrongdoing. Just to admit wrongdoing straightaway means that the game is over. Denying wrongdoing (by lying) always gives a chance to get away with [it]," he told Bored Panda.

While it may be hard to admit to mischief, it’s even harder to deny that hearing about these lies being called out in the open is a source of pure entertainment. After all, when people sense that their fibs can quickly get busted, they have to choose whether they want to tell the truth or double down. And that split-second decision can turn a well-crafted lie into an embarrassing disaster. Professor Vrij believes that we’re eager to read these amusing stories "because often people try hard to get themselves out of the situation whereas all they are doing is digging a deep hole for themselves."

We also managed to get in touch with Dr. Chris Street, a senior lecturer in Cognitive Psychology at Keele University, UK, who specializes in lie detection. According to him, research suggests that people are very good deceivers. "Liars do not avoid eye contact or make other bodily movements that we can use to detect them. As far as we know, there is no equivalent of Pinocchio’s nose that we can use to spot the liar," he told us.

"It is perhaps not surprising, then, that we are not particularly good at spotting lies. People tend to be ever so slightly more accurate than random guessing, but it is a very slight difference. Training to detect a lie can help a little, but not by much." Dr. Street explained that when we decide if someone is lying or telling the truth, we tend to guess that they are telling the truth rather than think that perhaps they are lying.

Dr. Street is also the author of the ALIED theory — The Adaptive Lie Detector account. His research showed "that we tend to guess others are telling the truth because making a lie-truth judgment is a very difficult one (after all, liars look just like truth-tellers). When there are no reliable pieces of information around to help us separate liars and truth-tellers, we rely on our past experience with the world, which is that most of us tell the truth most of the time," he explained.

The ALIED theory argues that a lie that is more likely to be believed is one that has reliable evidence that shows that the lie is actually a truth, Dr. Street told us. "This might sound contradictory, but this may not be as difficult as it sounds."

"Offering insider knowledge that supposedly would only be known by those who attended an event, for example, could be achieved by speaking to someone who attended that event," the lecturer continued. "Doctoring photographs may also lend credibility to a statement. Adding these 'convincers' may increase their believability, but it’s a high-risk strategy: if the person who is judging the statement has the means and sophistication to check up on your supposedly checkable detail (such as law enforcement), you could find yourself in a lot of trouble," Dr. Street explained.

While studies find that our ability to detect lies is no more accurate than a flip of a coin, professor Aldert Vrij pointed out that several conditions can allow us to spot someone’s fibs. "It will help to know the person well," he told us. "It also helps to know a lot of background information (evidence) about the topic so that the lie can be detected by comparing the statement with that evidence," Vrij agreed with Dr. Street’s line of thinking.

Finally, it helps to use specific verbal lie detection tools that have been developed, Vrij added. However, this is not straightforward. "[To use them] you need to know which questions to ask and which verbal cues to pay attention to. An example of one tool is to ask someone to back up their statement with independent evidence the interviewer can check, such as named witnesses who can confirm the statement, CCTV footage, receipts, phone use, etc.," he explained. "Truth tellers typically provide more evidence that can be checked than lie tellers," Professor Vrij concluded.
