According to a study described in an article on arstechnica, Scientists have found a strategy for winning at rock paper scissors.

No, this isn't a strategy of playing slightly slower than your opponent in order to read their choice first or an algorithm or anything. This study simply shows a collective, built in probability system that humans share.

Essentially, if you win a round, you are likely to use the same choice again in the next round. If you lose, you are more likely to switch. Chances are, your switch will be to whatever beats what your opponent just played. This means that if you win, you should actually switch to what beats the thing that beats what you just played, so as to counter the loser's second play. Read the linked-to article; they describe it much better.

I think it's a really cool insight into the human psyche, honestly, and I thought I'd share it with you.

Also, I'm going to actually win some ro-sham-bo now.
