Throughout history, there have been individuals who believe they’ve caught a sense of events yet to come.
True clairvoyance is unsupported by scientific evidence, but a subtle difference in how some people perceive the timing of events could help explain why many remain convinced of their psychic abilities.
A study by researchers from Yale University has provided some insight into why people think they have supernatural foresight, hinting at a physiological basis behind certain delusions.
The weight of evidence makes it fairly clear the human brain is not influenced by future events.
In many cases, proposed psychic abilities are the result of intentional fraud, with charlatans employing the same kinds of tricks mentalist magicians have used for centuries to feign mind reading and fortune telling.
But not all people who claim extraordinary abilities of future-sight are out to make a quick buck or two. Dismissing it as a sign of mental illness also tells us little about how such beliefs develop in otherwise healthy brains.
To gain an understanding of the neurological underpinnings of psychic prediction, the researchers made use of a test that had previously demonstrated a link between the timing of a colour changing shape, and the subject’s judgement of their ability to predict its transformation.
Only this time the researchers also evaluated the volunteers’ beliefs.

The online psychic industry is a seemingly bottomless collection of clairvoyants, tarot card readers, psychic healers, and other people in purple outfits. Like its predecessor, the psychic telephone hotline, and its contemporary, the “internet modeling” industry (which involves less clothing and more talking than the more traditional modeling industry), online psychics typically charge several dollars a minute for personal encounters, with some charging as much as $200 for a 30-minute session, making seeing a psychic often as expensive as seeing a therapist.
Those who doubt the existence of psychic abilities point to the fact that clairvoyance would go against everything we know about science. But the vagueness of psychic powers poses a real problem when someone offers them for a price: when a psychic’s service cannot be pegged down by science, the practitioner can claim to do nearly anything… including curing cancer, ending suicidal depression, or bringing a lover back who is long, long gone. In fact, I once had a psychic tell me that my newly-ended four year relationship was “not over yet.” Fortunately for me and my ex, she was wrong.
But what happens when someone goes to a psychic for something really serious? I visited one of the most popular live-psychic sites on the internet, Oranum, and spent five hours speaking to thirteen of their psychics. Knowing I would never again have the patience for such a venture, I picked the boldest claim I could think of: I told each psychic that I had serious, life-threatening cancer. At first, that was all the information they got. But if asked, I was prepared with a back story: It was stage 3 ovarian cancer, and among other treatments, my doctor wanted to me undergo chemotherapy. I instead preferred, I said, “to find a spiritual solution.”
How many of the psychics would offer to help me skip medicine in favor of psychic healing?
The first psychic I spoke to said that she could not tell me to stop seeing my doctor. “That’s against the law, okay?” she said, looking directly in the camera, at me and the others who were tuned into her “channel.” We were all typing in a group, trying to grab her attention, but the word “cancer” had apparently won. Someone else in the group thought she was talking to them anyway.
“Why are you talking about cancer? Oh my god, do I have cancer?!” they asked.
I quickly left, satisfied that this psychic had refused to endorse my choice not to get real treatment from a real doctor.
The second psychic, a young woman with only two other people in her chat room, was eager to . . .
