Steven Pinker’s Rationality is an interesting read. It offers a breadth of knowledge across fields of logic, statistics, and game theory, all without any of the tedium or dryness we’ve all experienced reading similar books. Pinker writes in a style that’s engaging and inviting, as if you’re allowing him to take the lead in a relaxing discussion of interesting phenomena. This book certainly doesn’t read like a classroom book, yet it manages to deliver more useful information than most classroom books could hope to aspire – knowledge you can apply to work, hobbies, and daily life.
At odds with conventional wisdom, Pinker advocates the proposition that humans are not inherently irrational, that our susceptibility to biases does not imply that we are irrational by default. Echoing the results of past research conducted with logic puzzles, he demonstrates that the simple actions of rephrasing and reframing confusing problems can significantly improve our chances of solving them correctly. This isn’t limited to logic puzzles or textbook problems. In this modern society, our lives are based on statistics, both in the choices we make, and in the presentation of those choices by the businesses we interact with. The human mind is not naturally adept with thinking statistically, but nonetheless, when met with such a problem, such as whether or not to trust the information provided by a news source, a simple reframing of the context can make all the difference.
Pinker then canvasses the main components of rationality: critical thinking, probabilities, evidence and belief, and game theory, before giving special attention to correlation and causation. He manages to strike a balance between depth and breadth – each of these topics could be the subject of a book, or even series of books, in their own rights. I’ve seen books falter in this balancing act before, either offering more depth than is appropriate for its target audience, or not enough to satisfy them. Rationality handles this perfectly.
I’d consider this book to be an effective blend of theory and practical insight. I’ve always firmly believed that true success, whether it be in your career, hobbies, or personal growth, requires a level of study beyond conventional wisdom. For true success, you must study the underlying structures that our daily lives are built upon. This book can be a useful tool in that pursuit for two reasons: its broad teachings will enable you to learn and evaluate ideas from multiple angles, and its contents itself is a suitable subject for such study, providing knowledge you can immediately leverage for your own personal improvement. Overall, I consider this to be a solid read for anyone looking to improve their own thinking or learn of the mind’s underlying structures in a somewhat informal manner.
