First of all, you must know that everybody lies! But if you’re worried that someone’s fibbing extends into the important stuff, like happiness or fidelity, you might have considered trying to catch them in a lie.
- Ask a friend.
Other people strangers, even have an uncanny ability to detect when something’s not right in someone else’s relationship.
BYU psychologists tested out this idea by having couples draw an object together, with one participant blindfolded and the other one giving instructions on what to draw. The whole thing was videotaped. Before they started, the scientists had the couples answer a few questions about their relationship in private, including whether or not they’d ever cheated.
Then, the researchers had a group of strangers watch the footage and guess which couples included a partner who’d ever cheated. The volunteers were surprisingly accurate.
Although preliminary, the research suggests that, simply by watching a couple doing something that requires working together, an outside observer may be able to detect infidelity or unhappiness.
- Mull it over while doing something else.
People are generally bad judges of character consciously, at least. When we are given time to process another person’s actions subconsciously, however, we’re far better at telling truth from deceit.
“These findings suggest that the human mind is not unfit to distinguish between truth and deception,” write the researchers in the study, “but that this ability resides in previously overlooked processes.”
- Listen carefully to the words they use.
For a recent study, Southern Methodist University Professor of Psychology James W. Pennebaker looked at some data he and his colleague Diane Berry had gathered from a text analysis program. They found that some specific patterns of language were helpful at predicting when someone was avoiding the truth.
- Listen to the sound of their voice.
Canadian researchers recently had a group of volunteers listen to a pair of voices and rate how attractive each speaker sounded. Then, the researchers asked them to judge how likely each person would be to cheat in a romantic relationship.
The female volunteers were most likely to say the men with lower-pitched voices would cheat; the men typically guessed that the women with higher-pitched voices would cheat.
Research has shown that men with more testosterone tend to have deeper voices, and as it turns out, higher levels of testosterone in men have been linked with higher rates of cheating. The jury is still out on whether there is any such association in women, though, and the researchers have yet to link their findings with actual observed behavior.
- Pay attention to social media use.
In his study, University of Missouri researcher Russell Clayton studied the social media habits of close to 600 Twitter users. Most people used Twitter for roughly an hour a day, 5 days a week. But those who used it more often than that were more likely to get in arguments with their partners, get divorced, or cheat. The more time they spent on Twitter, the worse the relationship outcomes were.
It’s unlikely that too much tweeting, posting, and liking caused other people to cheat, of course, but if anything the study showed that there’s certainly a connection between the two.
- Watch for sudden changes in behavior.
Sudden changes in body language, from facial expressions to patterns of speech, can be red flags for duplicitous behavior, according to research from Lillian Glass, a behavioral analyst who once worked with the Federal Bureau of Investigation to study how to spot signs of deceit.
If you’ve been with your significant other for a while, chances are you know how they normally act — what type of foods they eat, how they react to challenges or surprises, how well they listen, and so on.
- Look out for silence, personal attacks or repeating the question.
One tell-tale sign of lying is a sudden inability to speak. This happens because our autonomic nervous system often responds to stress by starving the mouth of saliva.
And in a study published in 2011, UCLA Professor of Psychology R. Edward Geiselman found that people who are lying tend to repeat questions before answering them, “perhaps to give themselves time to concoct an answer,” he said in a press release.
