Or we could just be really horrible. If we haven't even learned to avoid the one bias that we can measure super well and which is most susceptible to training, what are we even doing here?

You're fun to read. Posts explaining things and introducing terms that connect subjects and form patterns trigger reward mechanisms in the brain. This is uncorrelated to actually applying any lessons in daily life.

Two questions you might want to ask next year is "do you think it is practical and advantageous to reduce people's biases via standardized exercises?" and "Has reading LW inspired you to try and reduce your own biases?"
