Fact of the Day
At a symposium held at MIT, the abilities of fMRI (functional magnetic resonance imaging) brain scanning were debated, mainly concerning its use in lie detection [source]. Like a classic MRI, fMRI scanning can detect subtle fluctuations in brain movements. Sometimes, recording these movements while asking questions and getting responses can clearly show a person lying.
Unfortunately, many people are for this technology. This is unfortunate because there are many flaws in the detection of lies. First off, we still have a lot of grey area when it comes to understanding the brain. ScienceDaily.com has some pointing out that there are many ways to fool the fMRI. Simple things like doing math in your head can divert attention and activity away from lies. Also, the article mentioned that if someone were to know they were being tested, their nerves alone would make from an incorrect reading.
