Milwaukee, Detecting lies should not be done with specialized tools such as those often used by secret agents when interrogating the enemy. According to research, honest people can be distinguished from the builders devised based solely on the shape of her face.
The face is observed width of the face, on average, if the width then most likely the person is likely to prefer to lie. Conversely, if alias thin narrow face, then that person is usually more honest and trustworthy.
Certain ethnic groups might inherit the shape of the face is wider than the other ethnic.Because it is said to have a wide face is when compared with the average size faces on race or ethnicity itself, rather than the other ethnic.
This theory was proven in research Michael Haselhuhn, PhD, a professor of management at the University of Wisconsin in Milwaukee. In that study, Prof. Haselhuhn involving 115 college students regardless of their origin and ethnic background.
“Our findings indicate a person’s facial structure can show behavior associated with honesty. But we need to emphasize there are many other factors that influence it,” said Prof. Menshealth.com Haselhuhn was quoted as saying.
Prof. Haselhuhn added that this trend relates to alleged human instinct to avoid confrontation or disturbance by assuming the width of the face look more fierce.Because many are reluctant, then the wide-faced people tend to feel powerful and behave as they like.
However, until now the results of research of Prof. Haselhuhn has never been made standard for detecting lies. Tools, lie detector commonly used is still using old technology:
- Pneumograph, to detect the rhythm of breath, placed on the chest and abdomen, to work when there is contraction in the muscles and the air inside the tube.
- Blood Pressure Cuff, to detect changes in blood pressure and heart rate, affixed to the upper arm, working along with the sound that comes from the heart rate or blood flow.
- Galvanic skin resistance (GSR), to detect sweat especially in the hand, attached to the fingers, works by detecting how much sweat that comes out when under stress and lying.
