An ethical and effective way to detect lies has been discovered.
Most people lie sometimes and of course there are various ways to expose these lies, some of which are immoral and hurt people. Researchers have now found a new and effective way to detect lies that is accurate.
Accurate detection of lies is a difficult process, and lie detectors such as polygraphs, which work by measuring a person’s level of anxiety when answering questions, are theoretically inefficient. For example, if you are in a stressful situation, even without being guilty, you will experience stress and your answers will seem like lies.

Researchers have now developed a new method based on interviewing techniques and psychological manipulation to identify liars. Their findings are published in an article in the Journal of Applied Research in Memory and Cognition.
This new technique is part of a new generation of cognitive-based lie detection methods that is widely researched and developed. These approaches assume that the mental and strategic processes of honest people present in interviews are significantly different from those of liars. These differences can be reinforced and identified using special techniques.
Does lie detectors really works?
One of these approaches is called the Asymmetric Information Management (AIM) technique. This technique is designed to help suspects prove their innocence or guilt by providing accurate information. Small details are very important for legal research and can provide people with facts to investigate. Longer, more accurate statements and statements usually contain more clues to detect a lie than short statements.
The AIM method involves informing the suspects of these facts. In particular, interviewers tell people that if they make long, more detailed statements, they can better discern whether they are right or wrong. This is good news for truthful people and bad news for lying people.
Researchers have found that people behave differently when confronted with such a fact. Honest people usually make more accurate and lengthy statements to prove their innocence. Liars, on the other hand, seek to conceal their guilt and provide less detail so that the interviewer cannot detect their lies.
Asymmetry in the way liars and truthful people respond leads to two conclusions. When giving such instructions to individuals, they are more likely to be telling the truth if they make long, detailed statements to the interviewer. Liars, on the other hand, are more likely to make short statements.
Preliminary research on AIM has yielded good results. In the new study, 104 people were sent to different areas of the university to perform one of two secret missions. After a while, all of them were told that the data had been leaked and that all of them were suspects. Half of them were told that they had to tell the truth so that the interviewer could be convinced of their innocence. The other half’s mission was to tell a story, not to publish any information, and to prove their innocence in this way.
These individuals were interviewed and the AIM technique was used for half of them. Researchers have found that this method makes it easier to identify liars. False detection accuracy increased from 48% to 81% with AIM.
Researchers are exploring new ways to improve the performance of the AIM technique. AIM instructions can be easily understood and used. In addition, we are faced with an ethical approach.
