Imagine the following experiment: you wait say at a subway exit, and ask everyone passing "please tell me a number" (positive integer, of course). You do this day after day, until you reach say 1M people. 

- What is the distribution $\mu$ on the positive integers that you get?

This is a serious question, obviously some numbers are "nicer" than some other, say arithmetically speaking, so $\mu$ is probably a very interesting measure!

Of course, if you would do the poll with very small kids, $\mu$ would be more or less uniform on $2,3,4,5$ or so, perhaps with some mass at 1, and probably at $0$ too (coming from scientists's kids, proud of knowing what 0 is :) 

My question of course concerns adults, and results obtained via a real poll like the one suggested above: does anyone know, is anything written on this subject?  

(question inspired from http://mathoverflow.net/questions/117034/the-human-bodys-random-number-generator, I mean from the title of that question.)
