Putting my ipod on shuffle while I'm driving or walking is entertaining. Many days, it seems like it picks an artist and plays a not insignificant number of songs by that artist. It tends to gravitate a lot towards Simon & Garfunkel and Tom Petty. Yesterday, it had a thing for Don Henley and David Bowie. Today, it was Fleetwood Mac.

Funny how that works

I don't like pulling the "I'm an expert" card (Ph.D. in cognitive psychology), but the apparent non-randomness of iPod's shuffle does fit with a very common result in cognitive psychology: Human brains are so good at noticing patterns that they notice patterns that aren't actually there or aren't significant. "Random" doesn't mean "completely homogeneous", it simply means "affected only by chance"-- and randomness is sometimes "clumpy". What would be odd is if there were no "clumps" at all.

It's hard for human brains to recognize that truly random means that all data points are determined completely independently from each other. I know this, and still I have trouble wrapping my brain around it. ;)
