The questions for 2011 was: What scientific concept would improve everybody's cognitive toolkit? (So I understood this as a concept that would improve our powers of reasoning)
The thing I liked about this book was that you didn't have to jump in and read uninterrupted the many different answers. Each answer is given it's own chapter and title, each is a short essay. Some answers will be useful in your everyday life, some may be useful with something you are struggling with but all will provoke thought. Isn't that what a good book does?
I found some insight into fear/risk with two essays on uncertainty. Another essay , "Each of us is ordinary, yet one of a kind" by Samuel Barondes is particularly interesting. By being ordinary, we find compassion for others. By being one a kind, we find creativity and pride.
So, I can easily recommend this book, it will definitely make you smarter.
