Sources of Power How People Make Decisions
Gary A. Klein · 1998
In a sentence
Experienced people make effective decisions not by rationally comparing options, but by using intuition born of experience to recognize situations and mentally simulate a single, workable course of action.
Contrary to traditional decision-making models that emphasize rational choice and exhaustive option comparison, Gary Klein's 'Sources of Power' reveals how experts in high-stakes, time-pressured environments like firefighting, nursing, and the military actually make decisions. Through compelling real-world stories and the introduction of the Recognition-Primed Decision (RPD) model, Klein demystifies intuition, showing it's a sophisticated form of pattern recognition honed by experience. This book uncovers the true sources of an expert's power—mental simulation, storytelling, metaphors, and the ability to see the invisible—providing a revolutionary framework for understanding and improving decision-making skills in complex, uncertain situations.
The four lenses
- Science
- Statistics
- Systems
- Strategy
The model
This model, derived from 'Sources of Power,' illustrates how decision-maker experience and challenging task conditions influence decision effectiveness. The core process, based on the Recognition-Primed Decision (RPD) model, involves using experience for pattern recognition and mental simulation, which are the primary 'sources of power.' Challenging conditions moderate these relationships, making experience-based skills even more critical for success.
Decision-Maker Experiencecontextual condition
The accumulated, relevant, and practiced knowledge and skills a person has within a specific domain. This includes not just the quantity of time spent, but the quality of practice, feedback received, and the variety of situations encountered, forming the basis for expert performance.
Challenging Task Conditionscontextual condition
Environmental and task features that define a naturalistic decision-making setting, including time pressure, high stakes, inadequate information, ill-defined goals, dynamic conditions, and team coordination requirements. These conditions make formal, analytical decision strategies impractical.
Pattern Recognition and Intuitionpsychological state
The rapid, non-analytical cognitive process where an experienced decision-maker assesses a situation by matching its features to a rich store of patterns learned from experience. This allows for immediate judgments of typicality, anomaly detection, and the identification of a plausible course of action.
Situation Awarenesspsychological state
The decision-maker's holistic understanding of the current situation, derived from pattern recognition. It encompasses an awareness of plausible goals, critical cues that need monitoring, expectancies about future events, and the typical ways of responding in that situation.
Mental Simulationpsychological state
The cognitive process of imagining a sequence of events or actions to evaluate a course of action, diagnose a problem, or generate expectancies. It involves mentally 'playing out' a scenario to see how it might unfold and to identify potential flaws or opportunities.
Use of Analogues and Storiespsychological state
The cognitive process of drawing on specific past experiences, either personal or learned, to structure understanding of a current situation, generate options, and make predictions. This involves identifying parallels between the past case and the current problem to transfer knowledge.
Shared Team Cognitionpsychological state
The collective understanding and cognitive capabilities of a team, often termed a 'team mind.' It includes a shared situation awareness, common understanding of intent, and the ability of team members to anticipate each other's actions and information needs, enabling coordinated and adaptive performance.
Decision Effectivenessoutcome metric
The quality and timeliness of a chosen course of action, evaluated by its workability and success within the context of the situation. It emphasizes making a satisfactory decision quickly rather than an optimal decision slowly, and is the primary outcome of naturalistic decision making.
Adaptive Problem Solvingoutcome metric
The ability to improvise, create new courses of action, and spot leverage points when faced with ill-defined or novel problems. This goes beyond selecting a typical response and involves constructively building a solution tailored to the unique demands of the situation.

The story
The reader The reader is a professional, leader, or anyone responsible for making important choices in complex, high-pressure situations who finds traditional, analytical decision-making models impractical and insufficient for their needs.
External problem
The need to make good decisions quickly under conditions of uncertainty, high stakes, and incomplete information, where formal methods are too slow and cumbersome.
Internal problem
Feeling anxious about relying on 'gut feelings,' uncertain if their intuition is trustworthy, and frustrated by the gap between decision-making theory and real-world practice.
Philosophical problem
It's just plain wrong that the dominant models of decision-making ignore the power of experience and portray human intuition as a flaw to be overcome rather than a strength to be developed.
The plan
- Understand the limitations of classical rational choice models in real-world settings.
- Learn the Recognition-Primed Decision (RPD) model to see how experts actually make decisions.
- Master the key sources of power: intuition (pattern matching), mental simulation, storytelling, and metaphors.
- Apply these insights to develop your own expertise and improve your team's decision-making processes.
Success
- Becoming a more confident and effective decision-maker, able to trust your experience and make rapid, sound judgments under pressure.
- Leading teams more effectively by fostering a culture that values expertise and supports intuitive decision-making.
- Gaining a deeper understanding of human cognition that enables you to design better training programs and support systems.
At stake
- Continuing to feel paralyzed by analysis, struggling to apply impractical decision-making methods in time-critical situations.
- Remaining distrustful of your own valuable experience, leading to missed opportunities and slower, less effective choices.
- Failing to develop true expertise, leaving you and your team vulnerable in high-stakes environments.
Questions this book answers
- How do people make effective decisions under time pressure, uncertainty, and high stakes?
- What is the role of intuition in expert decision-making, and how does it actually work?
- Do experienced decision-makers systematically compare multiple options before choosing a course of action?
- What are the cognitive 'sources of power' beyond formal analysis that experts leverage?
- How can we train people to make better decisions in naturalistic settings?
Glossary
- Decision-Maker Experience
- The accumulation of relevant episodes, feedback, and deliberate practice within a domain that enables an individual to perceive situations differently, recognize a larger set of patterns, and possess a richer understanding of causal dynamics than a novice.
- Challenging Task Conditions
- A set of situational features common to naturalistic settings that make decision-making difficult. These include time pressure, high stakes, ambiguous or inadequate information, ill-defined or shifting goals, and dynamic (changing) conditions.
- Pattern Recognition and Intuition
- The core source of power where experience manifests as a largely non-conscious ability to size up a situation by matching its cues to a vast repertoire of learned patterns. This process generates a feeling of familiarity or anomaly, which the decision-maker experiences as intuition.
- Situation Awareness
- The product of pattern recognition; a mental model of what is happening that includes an understanding of the current state, its implications, and a projection of its future status. It integrates key elements of the situation into a coherent whole.
- Mental Simulation
- A conscious and deliberate cognitive process of constructing and running a dynamic model of a situation in one's mind. It is used to explain past events, project future outcomes, and evaluate the feasibility of a potential course of action by identifying its strengths and weaknesses.
- Use of Analogues and Stories
- The power to leverage experience by drawing parallels between a current, uncertain situation and a specific, well-understood past event (an analogue or story). This allows for the transfer of a causal structure, expectancies, and potential solutions from the known case to the new one.
- Shared Team Cognition
- The degree to which team members have a common understanding of the task, situation, and each other's roles and abilities. This 'team mind' enables members to coordinate implicitly, anticipate needs, and adapt collectively without explicit direction.
- Decision Effectiveness
- A pragmatic measure of decision quality in natural settings, focusing on whether the chosen course of action was workable, timely, and achieved the intended goals, rather than whether it was theoretically 'optimal.' A good decision is one that works well enough, quickly enough.
