idk the third place number off the top of my head, but that might be the case, although you would have to do some really weird data collection in order to get that number.

I think it's just something fundamentally pleasing about the number itself that the human brain latches onto. I suspect it has something to do with primes, or "pseudo" primes, numbers that seem like primes, but aren't since they're probably over represented in our head among "random" numbers even though primes are perfectly predictable.
