Summary
Chapter 9: We All Think We're Above Average (20 pages)
Hallinan talks about how people tend to believe that they're all above average. People are overconfident and it shows in things like golfing. The believes that this is caused by calibration, the difference between a person's actual and perceived abilities. He also goes on to talk about harder tasks and the overconfidence that comes along with it. People that are overloaded with knowledge believe they will be likely more right.
Chapter 11: We'd Rather Wing It (14 pages)
Hallinan talks about how professionals have difficulty knowing when they are good or bad at something. Experts become experts by practicing. At a young age, they construct a library of specialized knowledge. He ends by talking about how people tend do do things the way they first learned it.
Discussion
Chapter 9 was interesting because I see this happen all the time. I play a lot of sports and engage in a lot of little silly competitions with my roommates and I see this overhyping of ability all the time. Calibration is difficult and can be hard to reconcile.
We actually just discussed chapter 11 in class, regarding what people know and don't know. How do you know what you don't know if you don't know enough to know what you don't know? You know?
