Nassim Nicholas Taleb
About the author
Nassim Taleb, PhD, is a mathematical statistician, former options trader and risk analyst, and author of several influential books on the effects of randomness, probability, uncertainty, and ethics in financial markets and life in general.
General description
Skin in the Game is a book that expands on concepts that Dr. Nassim Taleb has written about in his previous books: Fooled by Randomness, The Black Swan, The Bed of Procrustes, and Antifragile. Dr. Taleb persuasively argues the importance of having a personal stake in the consequences of your decisions and behavior. The subtitle Hidden Asymmetries in Daily Life refers to the need for a reasonable balance between risk and reward for systems to be just. In this book, Nassim Taleb writes on themes of rationality and risk-bearing accountability across four areas of focus, which he describes as:
“Uncertainty and the reliability of knowledge (both practical and scientific, assuming there is a difference), or in less polite words bull***t detection”
“Symmetry in human affairs, that is, fairness, justice, responsibility, and reciprocity”
“Information sharing in transactions”
“Rationality in complex systems and in the real world”
Unique and most important aspects
In this wide-ranging book, author Nassim Taleb shares his philosophy on risk and ruin, and the pitfalls, individually and collectively, that arise when people manipulate situations to inappropriately remove their downside risks. In Skin in the Game, Nassim Taleb continues his signature writing style as he expands on themes from his Incerto series. While readers could start with this book, most people would understand the concepts he discusses much more quickly if they had read his previous books. He offers an interesting mixture of advice, opinion, and wisdom as he continues to add to his enormous collection of aphorisms, which he weaves throughout the text.
While I’m glad I read Skin in the Game, I found it more difficult to review than Dr. Taleb’s other books (see Len’s reviews) due to its meandering structure and rapid switching of tone, from lighthearted to harsh. The author is skilled at conveying complex ideas, but when distilling them, the concepts can crowd together. I also find myself disagreeing with some of his assertions and cringing at some of the abrasive things that he says. At times, I found Skin in the Game unpleasant due to the author’s criticism of people he either dislikes or thinks are idiots, or both. For example, he created the eponym “the Bob Rubin trade” for rent-seeking behavior (an ethical and economic “sin”). Important concepts of this book include:
The Silver Rule: “Do not treat others the way you would not like them to treat you“
The agency problem or principal-agent problem
The inverse problem in mathematics
The Intelligence of Time and the Lindy effect
Intellectualism versus scientism (“a naïve interpretation of science”)
Deontic libertarianism
How minority rule is “the mother of all asymmetries”
The curse of dimensionality
The Coase Theorem
The limitations of needing to be “employable”
The concept of theosis
Static inequality versus dynamic inequality
The idea of Prizes as a Curse
How education might be displayed as a luxury good
Ensemble probability versus time probability
Best quotes
“Skin in the game keeps human hubris in check.”
“By applying symmetry to relations between individuals and collective, we get virtue, classical virtue, what is now called ‘virtue ethics.’”
“Things designed by people without skin in the game tend to grow in complication (before their final collapse).”

“So employees exist because they have significant skin in the game—and the risk is shared with them, enough risk for it to be a deterrent and a penalty for acts of undependability, such as failing to show up on time. You are buying dependability.”
