It’s impossible to avoid bias, however whether the bias is bad or not depends on the bias and the situation. My go tos are people whose biases I think are either actively helpful (e.g. experts in a field who I’ve previously vetted), irrelevant to the topic (e.g. an NYT journalist talking about cheesecake in pre-war Cambodia), or who have a history of self-deprecating humility to the naked truth regardless of where it leads them but also not incredulous but humble to their intellectual limitations (very rare but occasionally stumbled upon).
