https://www.gwern.net/Mouse-Utopia https://www.gwern.net/Mouse-Utopia >Mouse Utopia is almost completely unpublished. Despite working on it and similar experiments with NIMH funding for decades (he “continued to work on his research results until his death on September 7, 1995”), Calhoun appears to have published almost nothing substantive about his research, limited to a handful of short summary articles or passing references. >It is unclear just how many experiments Calhoun had to run to get the one result which is always talked about; the name “Universe 25” implies at least 24 prior experiments, and Calhoun speaks vaguely of multiple “series” of experiments, referencing earlier experiments with stable populations (unlike Universe 25), some which were apparently controlled to fixed population sizes and some which apparently were not. Nor did all of the overpopulated universes develop the “behavioral sink” phenomenon Calhoun lays so much stress on, which he attributes to an otherwise-unexplained change in the food type. >No followup literature: only 2 partial replications have ever been done by third parties that I know of; likewise, if unique aspects of Calhoun’s experiment like the “beautiful ones” have been reported since, I have not encountered any references to them. They do not convincingly support the Universe 25 Mouse Utopia narrative.

I've noticed that there were a number of high profile social experiments around that time (50's-70's) that tried to show something inherent elements of humanity that cause us to turn evil. The Stanford prison experiment, Robbers Cave experiment, The Third Wave, etc. When you start to look deep into any of these, they all seem to have mostly been done by charlatans who manipulated results and sensationalized findings in order to get publicity.

  The popular-audience book Humankind by Rutger Bregman goes into the history of some of these classic experiments. In particular I was pretty shocked at how badly run the Stanford prison experiment was, and how lackluster and different the results were in the BBC's attempt to replicate. Granted, participants in that second experiment knew it would be televised, but that's not necessarily a recipe for good behavior, and they certainly engaged in conflict. https://en.wikipedia.org/wiki/The_Experiment https://en.wikipedia.org/wiki/The_Experiment

    It is good to debunk bad science. Just be careful not to repeat the same mistakes in reverse, throwing out something that is clearly helpful because the original experiment cannot be trusted. I'll post a very simple thought experiment to prove it for one of the cases: > No good evidence that tailoring teaching to students’ preferred learning styles has any effect on objective measures of attainment. There are dozens of these inventories, and really you’d have to look at each. (I won’t.) Now, do as in math and consider what happens when we approach zero: - what happens if a student cannot hear? - what happens if a student cannot see? or infinity: - can you think of a learning style that works better or worse for people who are strongly affected by ADHD? - same but for social anxiety? So, just by thinking about it for a few moments we can debunk the debunking: Clearly there exists whole subsets of the population (blind, deaf) where one or more learning styles are impossible, meaning that the rest of the learning styles must be better for those. What can we learn from this? Maybe to be sceptical, even towards the sceptics?

      That's why you use multiple approaches if you could. No real reason to limit yourself to only one preferred modality unless you're forced to.

        In case there was any reason to doubt: I agree.

  The world was still scarred by WW2, humans proved the worst if themselves just few years before. It's very reasonable that people were trying to find out why

From the video: "Eventually, the entire mouse population perished". I find that part pretty hard to believe unless there was some additional external factor. A population crash is one thing. But mouse society apparently collapsed to the point where every individual died?
