Synopsis: A trick for shared kitchens
Every time I see a handwritten sign in a college dorm, usually taped above the sink, with an admonition "please wash you dishes," I take a moment to appreciate the futility of such an effort. There are couple of ways to think about the problem of dirty dishes in a shared kitchen: prisoner's dilemma, a public good problem, and an externality model. The simple version is that it's not a great strategy to do all the cleaning, because other people will take advantage of you. Since the incentives are lined up this way, solutions can be hard to find. You could try and impose costs for dirty dishes, or try and make the culprit leave the apartment. Often roommates try to impose costs by yelling at the offender, or by putting dishes in that person's room or on their bed. Some of the most gossip provoking drama arises from just this type of action.
One of the above ways of thinking about the problem gives a pretty good solution. I'll explain the boring econ in the notes1, but to cut to the chase, establishing ownership of dishes is a smart solution. You can establish ownership of certain dishes by separating them from the other dishes. Putting them in an unorthodox place makes them unlikely to be used by someone who doesn't respect the ownership rule. If you stash the dishes you always use, you'll always have access to clean, free-loader-proof dishes. One important detail is to aim for having only one dish of each kind, because it forces you to clean it whenever you use it.
Now, if you feel bad for deserting the rest of your roommates via this idea, you can always wash some extra to assuage the guilt.
I've found that this solution is extraordinarily effective on the mission, and in college.
Notes:
1. Public goods are defined as goods that are both non-rivalrous and non-excludable. Non-rivalrous goods may be easily used by multiple people at the same time, and non-excludable goods are available to anyone, with no way of effectively preventing any individual or group from using them. When these two criteria are met, free-loading occurs any time someone is silly enough to produce the good, because everyone and anyone can use the good without paying. The Clean Bowl Club essentially makes "apartment cleanliness" excludable to anyone but the user of the Club. Notice, "clean dishes" is rivalrous in the first place, which means it isn't technically a public good, but "apartment cleanliness" is non-rivalrous, making it a public good. In application, non-excludability alone produces free-loading in the "clean dishes" case, which makes its elimination crucial. In the "apartment cleanliness" case, since The Clean Bowl Club only achieves rivalry, the problem is not totally solved; the apartment as a whole will probably look messy, but those in the Club have excludable clean dishes.
