Question for you: which of these two images shows dots that are placed at random, and which does not?
The problem with questions like this is that you already know it's the one on the left that's random, and the one on the right isn't, since you know I'm trying to trick you. But what's going on? Our brains love to find patterns in random noise. Look at the clumping of the dots on the left; surely that's not random? But it is. The distance between dots will average out to some number, but statistically you expect there to be some deviation from that average, so that some dots will be closer together (making clumps) and some farther apart (making voids). That's what's happening on the left. On the right, the random pattern that was generated was modified so that the dots would not be too close together. If a ...
