Mind-reading is Today

February 17, 2007

The movie Minority Report keeps tugging at today from tomorrow. The latest hook lies in a report on research that shows the possibility of predicting human action in advance by scanning the brain.

Tapping Brains for Future Crimes

A team of neuroscientists announced a scientific breakthrough last week in the use of brain scans to discover what’s on someone’s mind.

Researchers from the Max Planck Institute for Human Cognitive and Brain Sciences, along with scientists from London and Tokyo, asked subjects to secretly decide in advance whether to add or subtract two numbers they would later be shown. Using computer algorithms and functional magnetic resonance imaging, or fMRI, the scientists were able to determine with 70 percent accuracy what the participants’ intentions were, even before they were shown the numbers.

The study used “multivariate pattern recognition” to identify oxygen flow in the brain that occurs in association with specific thoughts. The researchers trained a computer to recognize these flow patterns and to extrapolate from what it had learned to accurately read intentions.

The finding raises issues about the application of such tools for screening suspected terrorists — as well as for predicting future dangerousness more generally. Are we closer than ever to the crime-prediction technology of Minority Report?
