Researchers say the use of brain scans in some death row trials in the United States could be expanded into the United Kingdom, where they might be used by police to detect whether a suspect is lying or is planning a crime.
Dr. Burkhard Schafer of the University of Edinburgh says other privacy concerns for brain scans include exploitation by employers to detect lying on résumés or by companies trying to analyze their customers´ preferences.
The scans are now so advanced that they can be used to determine things a person likes and doesn´t like, and reveal fears and anxieties. There are presently no guidelines for their acceptable use.
