We do it for many different reasons: It can be out of consideration, to avoid negative reactions, or for our own gain. Some people also lie to get a<br>kick , a so-called &quot;duper&#039;s delight&quot;. But is it possible to detect a liar? Yes, says the expert.

The aim is to get applause and attention, and this behavior is established in childhood.<\/p>\n<\/blockquote>\n\n\n\n<p class=\"wp-block-paragraph\">There are different types of lies and there are different types of liars. Perhaps the most notorious is the mythomaniac. But a type of liar that is both more common and harder to detect is liars who get high from being deceived. The intoxication is called \u201dduper\u2019s delight\u201d \u2013 the bluffer\u2019s joy. The term was coined by psychologist Paul Ekman and means that the liar feels pleasure, excitement or schadenfreude if he or she manages to deceive someone. The person gets an inner satisfaction from getting away with a lie or manipulation and then feels smarter than others. Many famous politicians have been identified as typical duper\u2019s delight people, not least the American President Trump. According to the Washington Post, Trump made 30,573 false or misleading claims during his first four years as president.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"683\" height=\"1024\" src=\"https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/logn-683x1024.jpg\" alt=\"\" class=\"wp-image-6314\" srcset=\"https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/logn-683x1024.jpg 683w, https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/logn-200x300.jpg 200w, https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/logn-768x1152.jpg 768w, https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/logn-1024x1536.jpg 1024w, https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/logn-600x900.jpg 600w, https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/logn.jpg 1300w\" sizes=\"(max-width: 683px) 100vw, 683px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">He is, however, in \u201dgood\u201d company with the likes of Britain\u2019s Boris Johnson and Hitler, who have both shown signs of duper\u2019s delight, according to experts. Such a sign is a diffuse smile of satisfaction and a total lack of signs of guilt. Researchers estimate that about 4 to 5 percent of the population belongs to this type of liar.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 In \u201dduper&#039;s delight\u201d, the person gets a kick when they manage to fool someone else by adding or improving a story. The aim is to get applause and attention, and this behavior is already established in childhood, says P\u00e4r-Anders Granhag, professor of psychology at the University of Gothenburg, who has researched the psychology of lying for several decades. The person may feel guilty about their lying and think \u201dI shouldn&#039;t have said that\u201d for fear of losing friends. On the other hand, the mythomaniac thinks this way, who lies compulsively and without purpose or meaning. The mythomaniac is less common than those who experience a duper&#039;s delight, but also easier to detect. There is no strategy here and they are not worried about being discovered. Behind the mythomaniac there are usually other mental disorders. For example, a psychopath can be a mythomaniac, or vice versa.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 The difference is that the psychopath lies more strategically than the mythomaniac. But neither the mythomaniac nor the psychopath worries about being exposed. They just move on to the next person, says P\u00e4r-Anders Granhag. He believes that skilled liars are usually verbal. Listening to what the person says is also usually the best way to expose the lies. That is why his research group at the University of Gothenburg listens to what the liar says and how a story changes when facts are presented.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 Both a liar and a truth-teller have the same goal. They want to be believed, but they take different paths to get there. The liar thinks and plans more, thinks more about what to say to convince others, and tells events in precise chronological order. The truth-teller, on the other hand, gives more detailed accounts than the liar, and it is more common for things to go wrong in true stories. The truth-teller may say: \u201dWe should<br>actually took my car but it broke down so we took the neighbor&#039;s instead\u201d. In a true story, the person can correct details such as \u201dwe went to the movies before dinner\u201d to \u201dno by the way, it was after dinner\u201d. The liar instead tries to avoid details that risk messing up the story.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThe liar also avoids changing his story spontaneously,\u201d says P\u00e4r-Anders Granhag. However, looking for a flickering gaze or nervous posture does not work to expose a liar, he says.<br>\u2013 It is a myth that you can tell if someone is lying just by looking at body language and behavior. 40 years of research shows that it doesn&#039;t work. A person may seem nervous out of fear of not being believed, and not because they are lying. Given that lying is so common, one might wonder if we humans even have<br>Lying is in our DNA. P\u00e4r-Anders Granhag believes so:<br>\u2013 Lying was necessary for our survival during evolution. If a person from a foreign group asked for the best hunting ground and you pointed in the wrong direction, you yourself gained an advantage. Then lying was a way to help your own group survive against other groups, he explains. Another example of a justified lie is<br>if a threatening person with a gun runs into a school and asks \u201dwhere are the students?\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 If the respondent lies, they may save lives and in such situations the lie is justified, even though we think it is ugly to lie. Lies can also be justified when we use them to protect other people&#039;s lives.<br>emotions. They can also be a sign that we are socially competent.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 We don&#039;t appreciate brutally honest people who say &quot;you look miserable&quot; to someone who has just had a haircut. We want people to be balancedly honest. Another occasion when we often lie is during job interviews. As many as 80 percent would consider withholding the truth then, research shows.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u2013 If the interviewee is asked \u201dis there anything else I need to know about you?\u201d at the end of the interview, it is unlikely that the person will admit that they shoplift from time to time. And it is a lie to withhold information that you know would be essential, concludes P\u00e4r-Anders Granhag.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\" width=\"683\" height=\"1024\" src=\"https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/Par-Anders-Granhag-683x1024.jpg\" alt=\"\" class=\"wp-image-6315\" style=\"width:322px;height:auto\" srcset=\"https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/Par-Anders-Granhag-683x1024.jpg 683w, https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/Par-Anders-Granhag-200x300.jpg 200w, https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/Par-Anders-Granhag-768x1151.jpg 768w, https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/Par-Anders-Granhag-1025x1536.jpg 1025w, https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/Par-Anders-Granhag-600x900.jpg 600w, https:\/\/inrikesmagasin.se\/wp-content\/uploads\/2026\/04\/Par-Anders-Granhag.jpg 1300w\" sizes=\"(max-width: 683px) 100vw, 683px\" \/><figcaption class=\"wp-element-caption\">P\u00e4r-Anders Granhag<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Det \u00e4r fult att ljuga, \u00e4nd\u00e5 g\u00f6r vi det, ofta flera g\u00e5nger om dagen.
