Getting closer to 'Minority Report'

In an experiment at mind-reading, a team of scientists used a brain scan to determine what somebody was thinking.

I am not making this up; the summary of the experiment was that by studying the brain through a MRI process and training a computer to read the results, scientists could determine whether subjects planned to subtract or add 2 numbers. The probability of determing this is 50%, but in the experiment, the scientists got upto 70% accuracy.

The current experiment is very limited, but given the speed of progress in research, it would not be very far away when we will get up every day and submit to a computer for it determine whether we planned to do something wrong that day. It may seem far away, and I am sure that it will take many years before such a capability is available, but it will happen.
