> And IIRC, interestingly they write that human capacity to create random numbers declines 25+. I can imagine that the older we are the more we look for something to make our decisions look more random based on what we've learned so far - more time, there was more time to look at more random number sequences - and the less random the outcome will be.
This is what they are testing, and at least based on the data they've got so far, it looks like it increases up to 25-ish and then stays pretty flat.
Another possibly interesting observation is that their preliminary data set (just eyeballing it, but) looks to have gotten
1) a flatter response
2) generally, less random responses
Which leads me to wonder if the live stats have been skewed more random as there might be some correlation between "interested in this sort of thing" and "has some idea what a random distribution ought to look like," and possibly this knowledge doesn't go away with age.
(human capacity to create random numbers declines 25+)
Not really; what they're testing is what kinds of response differently-aged people give to their question. So it's important what the question actually is; and it's important if the question might, for example, seem to older people to be a waste of their time.
They're not measuring what they claim to be measuring.
My opinion is that "real" randomness looks less random than artificial randomness.
That's why Apple changed iTunes random music shuffle to be less random because people complained that it wasn't random enough and replayed songs too close together.
