How to win at rock paper scissors.

Postby rabble » Fri May 02, 2014 9:39 am

Turns out, there's a trick to it revealed by game theory and some Chinese scientist who may or may not have too much time on their hands.
Researchers previously believed the game operated according to a game theory tenet called “the Nash equilibrium” — basically, the idea that people will chose each of the three options equally over time. But studied on a larger scale, it appears play follows a cyclical pattern — which means sneaky players can use “conditional response,” a reaction to a specific stimulus, in order to optimize their records.


If you win, you tend to go with the same play. If you lose, you tend to go to the next play but in a predictable order; rock, paper, scissors. If you play scissors and lose, most of the time you play rock next.

If you play paper and win, you usually go with paper next. But now you know your opponent will probably play paper because she played rock and lost. So you go with scissors.

But now we all know.

Have fun at the bars tonight!

Bah, mere child's play.

I prefer the more sophisticated rock-paper-scissors-Spock-lizard.

If you are challenged to a RPS contest at a bar, more advanced game theory indicates that you should always choose rock the first time. As your opponent gets ready to throw, punch them really hard with he rock, and then run as fast as you can in the opposite direction.

To my vast and complete surprise, so did about half the commenters on the articles.

I look forward to everyone's conclusion as to whether the expanded version behaves in the same manner as the original.
