I'm puzzled by the references to paper/scissors/stone. Why is "stone" the "most obvious move"?

Later on, the paper states that the game is "well known to be power law distributed". I couldn't immediately find anything online to back this up -- the first hit in google was a link to this paper. Can anybody provide some insight?

I was puzzled by that too. It seemed like the weakest thing in the paper. Other stuff, especially the part about applying contemporary risk models to historical data, was much more interesting.

Since the starting position (closed fist) is very similar to Rock, most people will be lazy and play Rock instead of Paper or Scissors, at least the first round?
