Chapter 1 What’s Sources of Power
“Sources of Power: How People Make Decisions” is a book written by Gary Klein. In this book, Klein explores the decision-making processes used by professionals in high-stakes, real-world situations. He argues that decision making is not always a rational and logical process based on gathering all available information, but rather something more intuitive and instinctive.
Klein introduces the concept of “recognition-primed decision making” (RPD) as an alternative model to the traditional rational decision-making process. RPD suggests that experts, based on their experience and knowledge, are able to quickly recognize patterns and cues in a situation and use them to make effective decisions without having to go through a step-by-step analysis.
The book delves into case studies and interviews with professionals in various fields like firefighting, military, and emergency medicine, highlighting how they rely on their intuition, mental models, and pattern recognition to make decisions under time pressure and uncertainty. Klein argues that these intuitive decision-making skills can be developed and trained, providing a more practical approach to decision making in complex environments.
Overall, “Sources of Power” challenges the traditional view of decision making and provides insights into how experts use their intuition and experience to make effective decisions in real-world situations.

Chapter 3 Sources of Power Summary
Sources of Power by Gary Klein explores the decision-making process of individuals in high-pressure situations, such as firefighters, emergency room doctors, and military personnel. Klein argues that traditional models of decision-making, which rely on careful analysis and rational thinking, are insufficient and do not accurately reflect how decisions are actually made in these fast-paced and ambiguous environments.
The book is divided into three main sections. The first section focuses on the recognition-primed decision-making (RPD) model, which is based on the idea that experts use their past experiences to quickly and intuitively recognize patterns and make decisions. Klein presents numerous case studies and interviews with professionals to support his argument that expertise is crucial in making effective decisions.
The second section explores the concept of mental models and how they influence decision-making. Klein explains that professionals develop mental models over time by learning from their experiences and reflecting on their actions. These mental models serve as a guide for decision-making, enabling experts to quickly assess situations and make effective choices.
In the third section, Klein investigates the role of intuition in decision-making. He argues that intuition is not a mysterious or supernatural phenomenon, but rather a result of expertise and the ability to access and leverage one’s mental models. Klein offers practical advice for developing intuition and leveraging it in decision-making.
Throughout the book, Klein emphasizes the importance of real-world experience, training, and reflection in developing expertise and making effective decisions. He challenges the prevailing notion that decisions should always be made through careful analysis and rational thinking, arguing that in high-pressure situations, intuition and pattern recognition are often more valuable.
In conclusion, Sources of Power provides a compelling argument for the importance of expertise, mental models, and intuition in decision-making. Through case studies and interviews, Gary Klein demonstrates how professionals in high-stakes situations rely on these sources of power to make quick and effective decisions.
