It's a great book that applies the economic thinking to unexpected scenarios. The main axis around which the chapters revolve is that people react to incentives. The plot twist comes in the form of the rule of unexpected consequences - in other words: goodwill can backfire in unexpected ways or how a destructive volcano eruption paired with a tsunami can save us from climate change. One of the most interesting takeaways from this book was the Peltzman effect (described in the addendum): the idea that if you implement a safety device, it might incentivize outsized risk-taking and thus the implementation of the safety device leads to even more harm rather than an increase in safety. I highly recomend this book for anyone interested in the unexpected laws of human nature that govern our everyday lives.
Good book, and interesting facts and data as always, but the chapter on climate change has aged like milk. It exuded 'tech bro' smugness, and I don't think a single suggestion in that chapter has come anywhere near fruition.
