A new study by scientists from the University of Portsmouth has revealed a new method to find out if people are lying. The way the method is implemented is quite simple compared to its importance.
Today, the most popular methods used to find out whether a person is lying or not depend on measuring a person’s heart rate or examining their facial expressions. But scientists have recently included these methods. managed to add another. The new method requires people to be subjected to multiple tasks during an interview.
In a new study by the University of Portsmouth, lying during an interview is more important than telling the truth. from the knowledge that it consumes more cognitive energy utilized. Based on this information, the scientists informed the person during the interview. assigning a secondary assignment demonstrated that it was effective in detecting whether the person was lying or not. Because the brain, which was already consuming more energy by lying, had difficulty focusing on the second task.
The lies are more understandable when given a secondary task in the interview:
The second task given to the subjects in the study in question was to ask them to remember a 7-number license plate again. However, emphasizing that this information is extremely important for the lie of the person to be revealed, therefore, the person’s brain it was necessary to spend more energy on the remembering process.
Of the 164 participants who participated in the study, first of all, various support or oppose social issues requested. Participants were then randomly assigned to the ‘true’ or ‘lie’ condition and interviewed the three topics they felt most strongly about. During the interviews, those who would give correct answers were instructed to state their true views, and those who would lie were instructed to lie naturally.
However, a group of a seven-digit license plate and they were asked to say it again to the person they interviewed. Participants were also given the opportunity to prepare for the interview and were encouraged to participate in the interview as persuasively as possible with a raffle incentive. The results obtained as a result of the interviews were that the stories of the liars were more accurate than those who told the truth, especially when given a secondary task such as remembering the license plate. is less believable and less clear revealed.
