Slate also tried a similar experiment, using an elaborate system of showing people fake images and asking them if they remembered them. They found that 15 percent "remembered" the faked images as real. And when asked if they remembered the event, if not the photo, up to 68 percent remembered certain events happening that never did. Their brains manufactured the memories spontaneously, because somebody showed them a picture of it. They could Photoshop an image from a famous protest to add in riot cops and violence, and the people would swear they could remember hearing about the riots. It doesn't matter that photo manipulation has literally been around as long as photos have; your brain still has a knee-jerk impulse to trust what it sees.
The best part is that instead of admitting that there's a conflict between memory and evidence, the brain lies and pretends as if it knew the answer all along. "Of course I remember those people, for I am an efficient machine of knowledge and am definitely not a haphazard pink wad of misfiring nonsense!"
