Discussion
In the conclusion of his book, Hallinan gives some advice on how the readers can apply the ideas presented in his book to their lives. Some of the things he recommends we keep in mind are:
1. Think small
2. Calibration can be taught
3. Creating a written record helps a person fend off the rose-colored-glasses of hindsight bias
4. In some cases it will be important to look for and even expect failure
5. Don’t be set in your ways
6. Slow down
7. Be aware of the anecdote (he references NutriSystem here)
8. Get plenty of sleep
9. Be happy
Hallinan concludes by discussing how money does not eliminate mistakes and is not the currency of life.
I have to say that I enjoyed this book. It was a good change from reading the other Norman books. In particular, I like how the author illustrates all his claims with interesting examples. I especially liked the Conclusion, because Hallinan does a great job of summarizing his ideas.I personally think this book will be beneficial in helping us better understand mistakes we make in our respective fields.
