I'd like to see a replication of the Mouse Utopia experiment. It seems to have the character of a lot of the "Failed to replicate" studies in psychology and sociology. The study finds a conclusion that is directly applicable to the issue of the day (overpopulation and overcrowding in Calhoun's time) and has an interesting metaphorical attention getting alarm to it ("We humans are the rats!"). One problem that stood out to me is how the mice in Calhoun's experiment are any different than any other kind of laboratory or pet mice. They are given unlimited access to food and water - but, aren't all pets and lab animals given all the food and water they want? What's special about these? Another problem is that Calhoun does a lot of evaluating rat behavior. They all eat together - is that abnormal? Some of the rats and lazy, and live by themselves. Is that abnormal? Some rats kill their young and the infant mortality rate rises as population density does. Is that abnormal? I'd like to see a modern recreation of it, along with better statistical representation of the data and the changes over time. If it's possible, I think a control setup should be added, where the rats in the control "universe" would have to engage in activities like their natural behavior to get food.
