Study Suggests Magnets Can Force You to Tell the Truth

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."

      You know... the funny thing is that this statement is much more true for magnets than it is for tides. Magnetism, like gravity, is a fundamental force that we can't explain. It just is. It is just one of the rules of the universe and we haven't been able penetrate other than to measure and bound it's behavior with mathematical equations.

      According to the article, it sounds like it would depend on whether they're facing east or west at the time. ;-)

      Although this bugs me:
      "The volunteers were presented a series of coloured discs, and told they could tell the truth or lie about the objects' colours while half were being stimulated on the left and half on the right. Results showed that the eight volunteers who had their left DPC stimulated lied more often, while the ones with the right DPC stimulated were more likely to tell the truth, researchers said."

      "More often" is nowhere close to "impossible". They don't say how much more, and it could be a very small percentage. If the percentage was large, I imagine the reporter would've put it in the article to make it sound more impressive and news-worthy (and the research team would've touted it loudly to get more interest and thus more funding). Also, there are no emotions or incentive involved in this case to lie or tell the truth and the subject knows it is a test, so it is more of a game than actually lying. Who knows what made the subjects change how they play the game? Maybe right-handed people get more annoyed by having magnets stuck to the left side of their head than the right side for some reason (right-handed people being the majority), and maybe the more annoyed the test subject is, the more likely they are to play the game negatively.

    Modern neuroscience is killing any wiggle-room that might have remained regarding souls and free will. As I've mentioned before, neuroscientists, ethicists, and legal scholars are concerned that "my brain made me do it" will become a reasonable courtroom defense. (No, I'm not talking about the traditional "insanity defense".)

    Yeah, I find the whole thing a bit dubious. It's not shocking to me that it might be possible to disrupt brain activity in such a way that a particular patient couldn't fabricate certain kinds of lies, but the idea that everyone's brain has a clear "lies on" and "lies off" switch that can be activated with a magnet.

    Reading one of TFA:

    The volunteers were presented a series of coloured discs, and told they could tell the truth or lie about the objects' colours while half were being stimulated on the left and half on the right.

    Results showed that the eight volunteers who had their left DPC stimulated lied more often, while the ones with the right DPC stimulated were more likely to tell the truth, researchers said.

    So it sounds like they were given the option of lying about something with no consequences, and they lied more often with one part of the brain stimulated. It doesn't say that it was "impossible" to lie, or even that it made it difficult to lie when strongly motivated to do so. Maybe it didn't directly cause them to be more likely to lie, but made them feel more whimsical or creative and likely to want to lie in a consequence-free environment.

    Then there's the much-overlooked difference between "not-lying" and "telling the truth". I can tell you something false because I'm mistaken, because I'm telling you a fictional story, or because I'm over-simplifying. None of those actions are deceptive in nature, but none of them are "telling the truth".

    Funny story.

    Friend of mine was driving back home from grad school for a short vacation. Got pulled over by some state troopers on the way home. Apparently he was driving a road that is frequented by drug runners from mexico and his little compact car was stuffed to the point of overflowing with random possessions. Trooper asks to search his car. He says no.

    Trooper then calls in a K-9 unit after mumbling something to himself, which walks around the car for many minutes without once alarming (barking). Obviously annoyed at this damned citizen who won't let him do what he wants, the trooper then moves my friend behind his police car and goes back to the car with the K-9 trooper. My friend sees them kick the car to get the dog to bark, and the troopers come over and inform him that the dog barking gives them right to search the car. They then spend the next half hour throwing his possessions all over the side of the highway. They found nothing and went on their way.

    Moral of the story is - it doesn't matter. The more authority we surrender, the more our 'rights' become meaningless in the face of an overwhelming corporate/government bureaucracy that protects its own rights over yours.
