A team of similar people is one mind, repeated, or: an open question I have not closed
Should a team be built out of people who resemble each other, or out of people who do not. My lean is toward the second, and this piece is mostly an attempt to work out how much weight that lean can carry. The literature turns out to agree with half of what I believed and to push back fairly hard on the other half, which is the more useful outcome of the two.
