This experiment is totally irrelevant to the disagreement between Diego and myself. Diego is claiming that making yourself have more sex--including sex you would otherwise be reluctant to have--will make you happier. He says he knows this because of some conjecture based on an ev-psych just-so story. Your experiment tests whether forcing people not to have sex they already do want to have will make them less happy. Do you not understand the difference?

If having epsilon much less sex would make us less happy, then having epsilon much more sex would make us happier, unless we are at exactly the local optimum, which sounds unlikely a priori.
