This may come as a shock if you're one of the fifty percent of Americans who believes in ESP, but it turns out that psychic powers don't show up in fMRI brain scans. A group of Harvard researchers scanned the brains of people who were receiving mental imagery from their relatives in another room, and discovered that . . . well, nothing happened. The best part is how they tested "precognition."
According to a release from Harvard:
To present stimuli telepathically, the researchers showed the photographs to the participants' identical twin, relative, romantic partner, or friend, who was seated in another room. To present stimuli clairvoyantly, the researchers displayed the photographs on a distant computer screen. And to present stimuli precognitively, the researchers showed participants the photographs again in the future.
How do you show something to somebody "again in the future"? Even though the brain scans revealed that nothing happens when you do any of this stuff, the Harvard researchers still have hope. They say this doesn't conclusively prove ESP does not exist.
