Generally, it is not necessary to understand every single type of cognitive bias in a nuanced way to mitigate the problems. Indeed, sometimes cognitive biases overlap to the extent that trying to mitigate one, you'll wind up affected by another. What's important is that your behavior and social rules be oriented towards uncovering truth through dialectic methods.
Jonathan Haidt, a moral psychologist, recently posted a terrific video on the the issue viewpoint diversity on college campuses-- specifically, the lack of it. Problems of confirmation bias are exaggerated, especially in social sciences, when there's a lack of viewpoint diversity on campus. When everyone likes the conclusions put forth by a paper, no one is motivated to find the flaws. Thus the flaws are not found, the flawed papers get cited by other papers, and you wind up with a knowledge base that is increasingly divorced from reality. Whether you know the name for that bias or not is less relevant than actually addressing the structural problems.
