Randomly assigned teams sounds like any straight out of college hiring pipeline, although controlled settings is harder. Google has done research on this, although I don't think they've done much with it.

Good point. I don't think Google did exactly that, but I did find this: https://hbr.org/2013/12/how-google-sold-its-engineers-on-man... It still is Google specific data though, so sadly it won't generalize as more than a set of ideas to test.
