Researchers found out that all you have to do to discover the facts is simply get the suspected fibber to do something else while recounting the possible lie.
A study was completed at the University of Portsmouth which involved 164 people.
Some of them were randomly selected to be liars when asked questions about certain topics, while others simply told the truth - researchers had to guess who was who, with participants receiving a cash prize if they managed to fool them.
Two-thirds of the group were also asked to remember and recall a car’s licence plate, with 50% of those people being told it was very important to remember.
The liars who had to remember the licence plate were largely found out. Basically, when asked to remember one thing and lie about another they folded quicker than an old lawn chair at a house party
Professor Aldert Vrij, who was in charge of the study, said that it is far easier to lie when there’s nothing else to do.
"When the opportunity to think becomes less, truths often sound more plausible than lies," he added.
Basically, keep those you think are dishonest busy, busy, busy.
Next time the flat’s having a group clean I’m gonna start grilling them. Who finished my leftovers? Who’s not doing their dishes? Who’s drunk texted my ex?
