The one thing I have been told is "real randomness clumps things together".

Hmmmm.

Ask people to spread themselves out randomly and the will spread out almost equidistantly around the space. Real randomness would have clumps of people together.

It's the same with coin tosses. people assume that because heads has come up twice tails is more likely but it isn't.
