When someone is lying to you personally, you may be able to see what they're doing.
- A study uses motion-capture to assess the physical interaction between a liar and their victim.
- Liars unconsciously coordinate their movements to their listener.
- The more difficult the lie, the more the coordination occurs.
The tell<p>Someone who is lying to your face is likely to copy your motions. The trickier the lie, the truer this is, according to experiments described in the study.</p><p>The researchers offer two possible explanations, both of which have to do with cognitive load. In a <a href="https://www.scimex.org/newsfeed/telling-a-really-big-lie-turns-us-into-copycats" target="_blank">press release</a>, the authors note that "Lying, especially when fabricating accounts, can be more cognitively demanding than truth telling."</p><p>The first hypothesis is that when someone is lying, their brain is simply too occupied with the subterfuge to pay any attention to the control of physical movements. As a result, the unconscious part of the liar's brain controlling movements defaults to the easiest course of action available: It simply imitates the motions of the person they're lying to.</p><p>The second possibility is that the liar's cognitive load deprives a liar of sufficient bandwidth to devise a clever, effective physical strategy. Instead, while lying, their attention is so laser-focused on their listener's reaction that the liar unconsciously parrots it.</p>

Credit: Niels/Adobe Stock<p>The phenomenon is referred to as "nonverbal coordination," and there is some existing evidence in deception research that it does occur when someone is under a heavy cognitive load. However, that evidence is based on observations of specific body parts and doesn't comprehensively capture whole-body behavior, and little research has mutually tracked both parties' movements in a lying scenario.</p><p>Nonetheless, say the authors, "Nonverbal coordination is an especially interesting cue to deceit because its occurrence relies on automatic processes and is therefore more difficult to deliberately control."</p><p>To track nonverbal coordination, pairs of participants in the study's two experiments were outfitted with motion-capture devices Velcroed to their wrists, heads, and torsos before being seated facing each other across a low table.</p><p>In the first experiment, a dynamic time-warping algorithm analyzed participants movements as they ran through exercises in which one individual told the truth, and then told increasingly difficult lies. In the second experiment, listeners were given instructions that influenced the amount of attention they paid to the liar's movements.</p><p>The researchers found "nonverbal coordination increased with lie difficulty." They also saw that this increase "was not influenced by the degree to which interviewees paid attention to their nonverbal behavior, nor by the degree of interviewer's suspicion. Our findings are consistent with the broader proposition that people rely on automated processes such as mimicry when under cognitive load."</p>
Mirroring<p>There is, it must be said, a third possible reason that a liar copies their target's behavior: Maybe liars are subconsciously reinforcing their credibility with their victims using "mirroring."</p><p>As Big Think readers and anyone familiar with the art of persuasion knows, copying another person's actions is called "mirroring," and it's a way to get someone else to like you. Our brains have "<a href="https://bigthink.com/mind-brain/mirror-neurons-smiling" target="_self">mirror neurons</a>" that respond positively when someone imitates our actions. The result is something called "<a href="https://imaginehealth.ie/the-psychology-of-mirroring/" target="_blank">limbic synchrony</a>." <a href="https://www.scienceofpeople.com/mirroring/" target="_blank" rel="noopener noreferrer">Deliberately mirroring</a> a companion's movements is an acknowledged sales technique.</p><p>So, how can you tell when mirroring signifies a lie and not benign interpersonal salesmanship? There is an overlap, of course — lying is one form of persuasion, after all. Perhaps the smartest response is to simply take mirroring as a signal that close attention is warranted. No need to automatically shout "<a href="https://64.media.tumblr.com/7a549060a9b05fc0a94d50dfe0bcbd9e/tumblr_n24teywDbO1tv5oaqo1_250.gifv" target="_blank">liar!</a>" when someone copies you. Just step back a little mentally and listen a bit more carefully to what your companion is saying.</p>

"Nothing but naked people: fat ones, thin ones, old, young…"
"The Yellow Sands", 1888, John Reinhard Weguelin; source: Wikimedia Commons<h3>Naked revolution</h3><p>Yet long before anyone knew about beach fashion, naturism was trendy. Bathing naked in the sea was going on in England as early as 1840. However, during the reign of Queen Victoria, this pleasure was outlawed. But it popped up again among the conservative Germans. In 1898, the first Naturist Club was founded in Essen and in 1900 the Wandering Birds group (<em>Wandervögel</em>) was scouring the country for uninhabited places and naked sunbathing. In the same year, Heinrich Pudor wrote <em>The C</em><em>ult of </em><em>the </em><em>Nud</em><em>e</em>, winning the hearts of contemporary supporters of naturism.</p><p>In the 1920s, on the back of this, members of the Movement for Natural Healing (<em>Naturheilbewegung</em>) organized naked sunbathing for the improvement of health. Persuaded by Pudor's theory of the healing properties of the sun and wind, which could be absorbed through the skin, they launched the naked revolution.</p><p>Pudor's book became the naturists' manifesto and soon after, not far from Hamburg, the Free Body Culture (<em>Freikörperkultur</em>, or FKK) movement was founded. This spread through other German centres and brought together thousands of people. The FKK still operates under the same name today.</p><p>The cult of the naked body even wrote itself into the ideology of fascist Germany, which advocated a pure, Aryan race. But in 1933, Hermann Göring issued an order that defined nudity as "the greatest threat to the German soul" and, with that, criminalized naturist organizations. But this wasn't the end of the movement. The naturists went underground, continuing their activities under the guise of improving physical fitness.</p><p>In 1936, the idea was even floated of having a naturist display to open the Berlin Olympic Games. It was quickly dropped. Despite this, in 1939 the naturists managed to organize their own Games in the Swiss village of Thielle.</p>
