Science proves that lying would have made Pinocchio's nose cringe
The classic image of the caricature of someone lying is to grow his nose, to Pinocchio, lying on a lost coin and observing his proboscis to stand out predominantly. However, a new study found that the opposite is true: the noses of liars actually shrink. Will Disney be forced to change the film and make Pinocchio's nose contract and peek out the back of his head?
"The new method for detecting lies in the laboratory is more precise than the polygraph and produces fewer false positives: it offers a level of accuracy of up to 80 percent and 20% false positives."
If you are wondering how researchers from the University of Granada in Spain managed to obtain a scholarship to study the relationship between the nose and the truth, the inaccuracy of the polygraph and other so-called detectors of lies is a good place to start. A university press release describes the study (a video explanation can be seen here), published in the Journal of investigative psychology and profiles of criminals, where scientists from the Center for Research of the Mind, Brain and Behavior (CIMCYC) of the UGR, in response to the growing demand for better security controls at airports, border crossings and police stations, observed thermography, using an infrared camera to detect patterns of heat and blood Flows into body tissues, instead of recording changes in pulse and respiration as the polygraph does.
"To lie you have to think, and that is why the temperature of the forehead increases, but we also get nervous, something that causes a drop in the temperature of the nose."
According to the principal investigator and co-author of the study, Emilio Gómez Milán, the team found that when a person lies, "the temperature of the tip of the nose falls between 0.6 and 1.2 ºC, while that of the forehead increases between 0.6 and 1.5 ºC. "The greater the difference in temperature change, the more likely a person is lying." The study involved 60 psychology students in the school.While they were connected to a thermograph, half of them were instructed to call. to a loved one and tell a real lie. (College students are calling home and lying ... talk about a low degree of difficulty!) The control group had to make a similar call and tell the truth about what they were watching on a monitor, the study found that thermography was much more accurate than polygamy.
"There is no method with 100% accuracy, since the difference between truth and lies is quantitative, not qualitative, but with this method we have managed to increase the accuracy and reduce the appearance of" false positives ", something which is frequent with other methods such as the polygraph ".
Yes Yes Yes. What's wrong with Pinocchio's nose?
Although it is difficult to see with the naked eye, the recumbent nose, at least its tip, shrinks as the temperature drops. While it would be a much less amusing caricature, the wooden puppet honker would have definitely shrunk by telling his lies. It turns out that the Disney version is inaccurate in another way. A different study at the Leicester University Center for Interdisciplinary Science it was found that if Pinocchio's head weighed 4.18 kg and his nose had six grams with an initial length of one inch that doubled each time he lied, only 13 lies would have made him reach the 208 meters and broke it. Neck of wood.
Now that I would teach liars a lesson!
