> Domain knowledge is great, but it can actually make you less open minded and unbiased
Is a bit strange to say, since it also undermines your position. If someone has domain knowledge in "managing", then your quote would suggest that they could be "less open minded and unbiased", and as such, a person without domain knowledge in managing might be better - in fact, an acorn (without knowledge in any domain) would be least biased. I'd argue that while you will gain biases as you gain knowledge, you will also be more knowledgeable about relevant things, and that's important. Thus, the best person for a managerial position would be someone with knowledge about managing people and with knowledge about what those people are doing.
