Scientists Can Read Your Mind!!
You know how in sci-fi shows, whenever they want to make a cheap clip show, they’ll hook a character up to a device that reads their mind and displays what they are thinking? Yeah, turns out that’s not unrealistic.
Now, this is a long way from practical use, obviously, but the fact that a brain scan can show that much detail already means someday it could be very precise. Most of the possible practical uses are very awesome (helping communicate with injured or disabled people for example), they could also be used for EVIL. Such as a woman asking what you’re thinking about, and then flipping on the fMRI machine to see if you lie to her.
