Most people have experienced that nagging feeling that something is off during a conversation. Whether it is a colleague explaining a mistake, a friend sharing a story, or someone making a promise, it can be difficult to know when the truth is being stretched.
According to behavioural expert and former U.S. Navy chief Chase Hughes, many of the common beliefs about spotting a liar are misleading.
Speaking on the Dream Out Loud podcast, Hughes argued that individual body language signals rarely tell the full story. Researchers in psychology and communication have long warned against relying on a single gesture as evidence of deception, reports LADbible.
Small changes matter
Rather than focusing on actions such as looking away, crossing arms, or touching the face, Hughes believes people should pay closer attention to changes in behaviour.

The key, he says, is to establish what is normal for a person and then watch for sudden shifts. Changes in speech patterns, breathing, hand movements, or overall behaviour can sometimes reveal more than the words being spoken.
This approach is often referred to as behavioural baseline analysis, a method used in communication training and investigative work.
Context is crucial
Experts also stress that body language should never be viewed in isolation. A person who appears uncomfortable may simply be tired, stressed, or distracted rather than dishonest.
Instead of searching for one definitive sign, specialists recommend looking for a combination of behavioural changes that appear together. This broader view provides a more reliable picture of what may be happening.

Asking better questions
The questions being asked can also play an important role. Open-ended and less specific questions may encourage more natural reactions, making inconsistencies easier to spot.
While no technique can guarantee that a lie will be uncovered, understanding behavioural patterns may help people assess conversations more accurately.
