When you were a kid, did you play Spot the Difference?
You might remember the game from the back pages of magazines or restaurant menus. Two pictures side by side, with several subtle differences. Ideally, they were challenging enough to keep you out of your parents’ hair for at least a few minutes on a long car ride or wait in the doctor’s office.
Now, imagine playing the same game today – but the two images are placed in separate rooms, and you have to walk back and forth between them. Or the pictures are tiny thumbnails, and you need to squint to see the details. Or you’re working with a partner, and you can each only see one visual. You’d feel like the game was rigged – and you’d be right.
