Estonian researchers claim that magnets can either force you to lie or make it impossible
. Subjects in the study had magnets placed at either the left or the right side of the dorsolateral prefrontal cortex, and the results suggest that the individual was either unable to tell the truth or unable to lie depending on which side was stimulated
. From the article: "Last year, researchers at the Massachusetts Institute of Technology also used powerful magnets to disrupt the area said to be the brain's 'moral compass
,' situated behind the right ear, making people temporarily less moral."
