The Pinoc­chio Ef­fect... Ly­ing gives you a cold nose!

Irish Daily Mail - - News - By Vic­to­ria Allen

NEVER mind cold feet – it’s a cold nose that might re­ally give away your feel­ings.

A ‘Pinoc­chio ef­fect’ which sees peo­ple’s noses get colder when they are ly­ing could work bet­ter than a lie de­tec­tor, sci­en­tists say.

Record­ing the tem­per­a­ture of some­one’s face can de­tect if they are fib­bing with 85% ac­cu­racy, the re­searchers found.

That is be­cause the tip of the nose is sen­si­tive to some­one’s emo­tional state, and ly­ing is a stress­ful ac­tiv­ity.

Re­searchers worked with 60 stu­dents, who un­der­took tasks while be­ing filmed by a tem­per­a­ture-sen­si­tive cam­era.

One task was to make a tele­phone call in which they told a lie, such as say­ing they had seen a celebrity. Among the liars, 85% saw their nose tem­per­a­ture fall.

An­other clue, seen in six out of 10, was an in­crease in fore­head tem­per­a­ture be­cause of the men­tal ef­fort in plan­ning a lie.

Th­ese tem­per­a­ture changes were ab­sent in peo­ple who made hon­est tele­phone calls.

Pro­fes­sor Emilio Gómez Milán, at the Uni­ver­sity of Granada, said: ‘The ex­per­i­men­tal group ex­pe­ri­enced the so-called “Pinoc­chio ef­fect” in the nose and the ef­fect of men­tal ef­fort in the fore­head, which al­lowed us to mon­i­tor the lie.’

The re­searchers put their method’s ac­cu­racy at 10% higher than a lie de­tec­tor test.
