MRI: The Ultimate Lie Detector? (What questions would you ask...)

[BurgherHoldtheLies]

“With fMRI, you are looking directly at the brain’s activity,” Faro said. “And lying is cognitively quite hard. Watching brain activity provides a more reliable indicator.”

In his study, Faro asked six of 11 volunteers to fire a toy gun and then lie about whether they had pulled the trigger. The other five were asked to tell the truth about what had happened.

Each of the volunteers was then scanned with fMRI while being asked questions about the incident. A traditional polygraph test was also carried out to compare the accuracy of the two methods.

In all cases, the fMRI accurately distinguished between the volunteers who were telling the truth and those who were lying.

Mr. President, did you really believe there were WMD's before invading Iraq?

1. Anyone with shrapnel, sheetmetal or a pacemaker couldn't be tested

Small flaw. Cheney couldn't be tested.

3. Article didn't say if pathological liars and sociopaths were outed by MRI

Someone who is basically honest telling a lie might work harder at it than someone who just lies all the time or someone who just doesn't feel normal inhibitions on bad behavior. Would like to know how the tests worked on them.

No point in throwing pols into the machine if it doesn't out the compulsive liars ;)

5. I can dream, can't I? Mandatory testing for all elected officials!
