Researchers at the University of Washington just demonstrated that two people could work together telepathically to play a video game.
One player could control another player's hand with his thoughts
How did that work? One of the subjects could see the game, but had no controller. His partner had a controller, but couldn't see the game. By using electrodes and electromagnets, the researchers created a way to allow the first person to control the second person's controller hand just by thinking about it.
It's pretty impressive — although the experiment doesn't quite mean we're on the cusp of being able to read each other's minds. For one, telepathically controlling hand twitches isn't quite the same as sharing ideas, thoughts, or dreams.
This telepathy research could end up being largely useless — or it could be what everyone ends up doing in a few decades. Here's what you need to know about recent advances in this field:
