You're so Psychic, Bet You Know This Podcast is About You

Two Harvard psychologists use neuroimaging to provide what some call the best evidence yet that extrasensory perception (or ESP) does not exist.

How fortunate it would be to predict your future, see things in other places, read minds… Yes, if we had ESP, think of the thousands we save not attending therapy.
 
But what if ESP were scientifically, once and for all, debunked?
 
Well two Harvard psychologists say they’ve published the most definitive evidence against ESP in this month’s Journal of Cognitive Neuroscience.
 
Their theory is that if ESP exists, subjects’ brains would respond differently to ESP-related stimuli than to non-ESP-related stimuli.
 
They studied three kinds of ESP with subjects inside an fMRI scanner:  telepathy, clairvoyance and precognition.
 
Telepathic stimuli were photos shown simultaneously to both subjects and their close partners (like an identical twin). Clairvoyant stimuli were presented on a computer in separate room. Precognitive stimuli were shown to subjects at a later time.
 
Here’s the thing: pictures perceived through ESP, should spark a suppressed brain pattern – since, the brain reacts differently to previously seen stimuli, than it does to novel stimuli.
 
Alas researchers found no difference in the brain pattern between ESP and non-ESP stimuli.
 
Of course, getting a null result doesn’t confirm that ESP doesn’t exist somewhere…it just weakens the possibility.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
