I'm always reading something, usually multiple books at a time.
Daniel Kahneman uses the metaphor of "System 1" and "System 2," coexisting "characters" in our brains responsible for the two types of thinking the book's title alludes to.
* System 1 operates automatically and quickly, with little or no effort and no sense of voluntary control.
* System 2 allocates attention to the effortful mental activities that demand it, including complex computations. The operations of System 2 are often associated with the subjective experience of agency, choice, and concentration.
System 1 is in charge of our brains most of the time, making quick, intuitive judgments. System 1 relies heavily on our biases, without our necessarily being aware that this occurs. When confronted with a complex question that needs the resources of System 2, System 1 is liable to make a quick substitution, answering a simple, replacement question instead.
System 1 can serve us well, except when it doesn't. It's a feature that can sometimes be a bug, and this book provides a series of frameworks that can help identify when it's useful to hack our systems and get the most out of the two systems.
As I mentioned in my review for The Undoing Project, I've become fascinated by behavioral economics and the thinkers whose work has shaped it. I will say that this is very much a system 2 book. It should be read carefully, and I hate to say it, but I realized by listening to this, that audiobooks lend themselves more to system 1. The upshot is I often found myself rewinding to listen to something I realized my brain had only partially taken in (because it decided to go off on a side trip). I also checked out the hardcover edition from my library, and I intend to review it.
The value of this book is understanding how to make better decisions and create frameworks that also help others to do so.
