Neuroscientist Uses Brain Scan to See Lies Form

Here's the link to my article from Tuesday.

  1. I wonder what the effects of rehearsal are on this method of lie detection. If the fMRI shows the mental work of creating a lie, what happens if the person has prepared what they will say ahead of time, and therefore does not need to think about it at the time of the test?

  2. The thing that interested me most about this article is how ethics would figure into it. Much like any technology that promises to get a handle on the way things have "naturally" occurred for the past X-years (I'm thinking: stem-cell research), questions of ethics are to be expected and considered.

    That said, Wolpe's argument ("What happens if No Lie or one of those companies images someone and finds a brain tumor?...No Lie is not a medical institution. They don't have the resources to take care of that.") didn't make much sense to me: in such a case, it would make sense to inform the person being scanned of what was found, and advising them to get it checked out. Done deal. How is that ethically problematic?

  3. Two sort of related questions: I know that current lie detector tests can be fooled into believing that someone is telling the truth when they are lying. Could there be a way for someone to "coach" themselves to trick this test? Secondly I wonder how "lying" would look in the brain to a sociopath who does not believe they did wrong or someone else who had no idea that they were lying?
