I would agree. For me, the most important thing to know is that there are biases that could be impacting me and to always leave room for a) a competing viewpoint can be sincerely held and possibly correct over the viewpoint I am convinced of, and b) to always ask myself if there is a self interested reason I want the belief I hold to be true.

Many biases cannot be overcome even with knowing about them... but accepting that it's possible I'm wrong and that the crazy guy on the other side is both sincere in his competing belief and possibly correct, allows me to evolve and learn and ultimately get along with more people.

I have some strongly held beliefs and opinions...But I try to keep my mind open and without considering cognitive biases, you are going to be more close minded than you should be in most cases.
