Von Hammad Siddiqi stammt ein Paper mit dem Titel „The social norm of leaving the toilet seat down: A game theoretic analysis“ (2006) veröffentlicht. Wie der Titel schon besagt, untersucht er das Problem des Klositz mit spieltheoretischen Mitteln. Einerseits ist nicht die optimale Lösung, den Klositz immer zu senken, wenn man die Anzahl der Klositz-Bewegungen pro Haushalt minimieren will, andererseits setzt sich der Mann einer für ihn negativen Situation aus, wenn die Frau einen aufgestellten Klositz entdeckt. Dieser Aspekt bringt die Spieltheorie „ins Spiel“.

Ein Auszug:

If a female finds the toilet seat in a wrong position then she will most probably yell at the male involved. This yelling inflicts a cost on the male. Based on this omission, women may argue that the analysis in these papers is suspect.
In this paper, we internalize the cost of yelling and model the conflict as a
non-cooperative game between two species, males and females. We find that the social norm of leaving the toilet seat down is inefficient. However, to our dismay, we also find that the social norm of always leaving the toilet seat down after use is not only a Nash equilibrium in pure strategies but is also trembling-hand perfect. So, we can complain all we like, but this norm is not likely to go away.
All hope is not lost though. An important issue regarding social norms is whether they are created to increase welfare. Are they society’s response to market failures? One such norm is tipping for service quality. Azar (2003) has shown that the norm of tipping increases social welfare. In this paper, we show conclusively that the social norm of leaving the toilet seat down after use decreases welfare and by doing that we hope to convince the reader that social norms are not always welfare enhancing. Hence, there is a case for scientifically examining social norms and educating the masses about the fallacy of following social norms blindly.
