Let's be honest for a second - most of us are guilty of lying. Whether it's a little white lie here or there, or getting caught up in a big whopper. Dishonesty is common in our society. From politicians and lawyers to grandmas and six-year-old's. Lies happen, large and small. And some lie more than others. You may know someone who is extremely prone to lying. Perhaps you've referred to this person as a compulsive liar. Have you ever wondered why liars keep lying? A team of researchers at University College London wanted an answer to this question. So, they conducted an experiment.
The Study
Researchers recruited 80 participants for their study. It was published in the journal Nature Neuroscience. They monitored the participants' brain activity using a functional magnetic resonance imaging machine or an fMRI. Researchers noted the difficulty of the study in using brain scans. Participants would need to "repeatedly, deliberately and voluntarily act dishonestly in a social context without being required to admit their dishonesty." To work around this, the research team created an experimental model. This allowed them to observe deception using a trail-by-trail method. Using this new method, each person in the study advised their partner on the amount of money in a glass jar filled with pennies. There were certain incentives involved which served as the motivation to deceive the partner. Over the course of the experiment, the incentive model was changed. The money would either benefit or harm one of the two partners. In every case, the study participant was required to lie in order to benefit himself. More simply put:- Experiment 1: Both the participant and partner benefit if the participant lies; only the participant benefits if they lie; only the partner benefits if the participant lies
- Experiment 2: Only one person benefits. Either the participant benefits or the partner benefits if the participant lies
