Like if he said bird, we would automatically picture a type of song bird instead of something like a penguin. He talks about trial and error and how its not the best way to solve problems even though it works. He also talks about algorithms and heuristics.He also talks about confirmation bias and how most of the time we are overconfident in our answers.
