Yet, a formal method should only really be needed once the bias is found to actually exist on a individual level. Everything else would be insane.

Wouldn't a better approach be incorporating formal, rational methods into everyone's individual thought processes from the beginning? In other words, I believe adopting the overt rationality advocated by the likes of http://lesswrong.com/ would almost automatically correct a lot of societal problems caused by bias.
