When pulp science fiction meets reality, courtesy of MIT:
Liane Young and colleagues applied transcranial magnetic stimulation (TMS) to disrupt neural activity in an area of the brain known to process information about beliefs and then asked twenty subjects to rate actions on a scale from one (morally forbidden) to seven (morally permissible). The researchers report that study participants judged actions in which a person believes he or she will cause harm to another person-but fails to do so-were more morally permissible during TMS application to the brain region responsible for processing beliefs, compared to when TMS was not applied, or applied to other brain regions.
At last, with the power of magnets at my disposal, I and my army of mind-controlled slaves will conquer the world*!
