Prime, I don’t know if you’re being sarcastic or serious, but I would be interested to see such a study. Or more of them (see links). I don’t know how one would go about setting it up though. I’m pretty sure that confirmation bias has been discussed in relation to State bball, and I’m probably guilty of that to an extent.
I have bookmarked some relevant studies, probably posted these before but here they are again. There’s some interesting information in them, enough for me to conclude that there is probably both conscious (acknowledged “tendencies”, personal agendas, aka the KH Effect) and subconscious (the Blues are just “better”) factors at work.
