If you think you’re a psychic, here’s a simple test:
Get a hundred boxes, and have someone put a loaded gun in 99 of them.
In the hundredth box, have them put an unloaded gun.
Then, use your psychic powers to find the box with the unloaded gun.
After you select that box, take out the gun, put it to your head, and pull the trigger.
If the gun doesn’t go off, you’re psychic.
If the gun goes off, you might still be psychic.
You can still prove that you are telekinetic. Bend the bullet’s trajectory away from your brain.
