Hm. People (at least I do) have a bias towards small numbers. Given the choice, I'd probably choose something below 20. I don't know how representative I am of the general population, but I'd guess the average to be around 15 and choose 10. --- SPOILER BELOW EDIT: I tested myself on http://twothirdsofaverage.creativitygames.net/ http://twothirdsofaverage.creativitygames.net/ (linked from the wikipedia article) and entered 9. The actual average was 14.
