By what method do humans generate random numbers?

I mean attempt to generate random numbers, since what they generate isn't very random.

With numbers in general (not necessarily random numbers), we remember numbers based on availability. If you're around a certain number more often you're more likely to think of them first. The numbers that would pop into your head are numbers that are more available to you at the time. 

This follows a general pattern in retrieval of information from long-term memory into working memory, in that we retrieve information based on their associations with other information. You are more likely to remember information you learned in the same surroundings you learned it; you are more likely to remember something if you are primed with something related to it. 

[Speculation warning] Perhaps we associate certain numbers with being "random". Given that we are primed to think of random numbers, we remember those numbers associated with being random (rather than creating a novel set of numbers from scratch.)
