Wissenschaftler an der Zhejiang Uni in China haben herausgefunden, dass meine Schnick-Schnack-Schnuck-Strategie für faule Säcke™ tatsächlich häufiger zum Gewinn führt. Ich hab' mir irgendwann mal angewöhnt – ich wende die Schnick-Schnack-Schnuck-Strategie für faule Säcke™ nicht wirklich konsequent oder immer an, aber häufig –, mich bei dem Spiel am Anfang auf ein Item festzulegen und genau das in jeder Runde zu verwenden. Meistens nutze ich Stein, weil man so nichtmal mehr die Hand formen muss, was einem faulen Sack wie mir sehr zuvor kommt. Jedenfalls: Schnickschnackschnuck, Science, China…

Zhijian [Wang] carried out their experiments with 360 students recruited from Zhejiang University and divided into 60 groups of six players. In each group, the players played 300 rounds of Rock-Paper-Scissors against each other with their actions carefully recorded. As an incentive, the winners were paid in local currency in proportion to the number of their victories. […]

The results reveal a surprising pattern of behavior. On average, the players in all the groups chose each action about a third of the time, which is exactly as expected if their choices were random. But a closer inspection of their behavior reveals something else. Zhijian and co say that players who win tend to stick with the same action while those who lose switch to the next action in a clockwise direction (where R → P → S is clockwise).

This is known in game theory as a conditional response and has never been observed before in Rock-Paper-Scissors experiments.
