The Police State will Soon be Looking at Your Thoughts, Govt Dumping Money into “Brain Scanners”

The polygraph machine may be a failed experiment in reading minds, but lie detection is nonetheless desired by authorities. Criminal courts could one day be peering directly into a person’s brain for evidence.

This would be accomplished using “Functional Magnetic Resonance Imaging” (FMRI), turning a medical procedure into the new lie detector. FMRI measures blood oxygenation in the brain over time, correlating brain states with ongoing behavior under different conditions.  Inferences are made based on contrasting measurements between “lying” and “not-lying” conditions.

Government and private companies alike are pushing acceptance of brain-scanning for evidence. In its post-9/11 paranoia, the US poured money into the development of fMRI lie detection as a tool of interrogation.

Private companies such as No Lie MRI and Cephos Corporation already provide the service of fMRI lie detection for employment screenings, and are seeking its use in criminal court. No Lie MRI cited a study funded by the US Defense Advanced Research Projects Agency (DARPA) as part of its justification.

FMRI is a valuable tool in the field of cognitive science, giving us insight into psychological and neural processes. However, its usefulness in lie detection is questionable.

Zachary Shapiro of Harvard Law points out that neuroimaging for the purpose of lie detection is not generally accepted in the scientific community, as peer-reviewed studies have small patient bases and are not representative of the general population.

Other factors, such as the ability of a person to trick the machine, and jury bias based on the veneer of scientific technology, outweigh its potential.
