Serious disappointment. It mostly re-iterates the content of other books & very fundamental concepts (e.g., expected value), but in a very shallow and uninspired way (e.g., when discussing expected value, the author barely scratches the theory and completely ignore the real-life challenges with applying it). The most frequently quoted books: "Thinking fast & slow", "Thinking in Bets", "Nudge". But don't expect in-depth analysis, just a direct referral to key concepts/conclusions.
The examples brought to illustrate the ideas aren't just poor matches (surprisingly poorly correspond to the ideas covered) but also have one common denominator - DEI & social justice. So you can find here the usual suspects: Kapernick, George Floyd, etc. I guess they are aimed to inspire? and because wokeness was selling books few years ago ... Don't get me wrong - I'm generally apolitical and I believe the free thought matters: one can learn from experiences/events from all sides of political scene. But in this case, this really looked more like a liberal crowd-pleaser, than applying an adequate situation to illustrate a concept it exemplifies.
Long-story short, this book is a waste (of time/money). Reach out to the roots (books it refers to) - these are far better, far more thought-provoking. I literally made zero notes from "Decision Leadership" and that doesn't happen frequently in my case.
