This is certainly not a new book (the most recent edition came out in 2018), but I only recently became aware of its existence and relevance to risk and crisis management. Richards Heuer enjoyed a distinguished career in the CIA and wrote the book primarily for his fellow intelligence professionals (and consumers of intelligence such as politicians). However, the central focus on making sense of complex and confusing situations, where the impact of mistakes is very high, has obvious relevance to the fields of risk and crisis management.
Heuer approaches a broad sweep of psychology, as it relates to intelligence analysis, beginning with three chapters on our “Mental Machinery”. Of particular interest is his discussion of how we store and retrieve memories. This provides the foundation for the core of the book “Tools for Thinking”. These tools include various strategies for generating hypotheses, on the basis of limited information, and choosing amongst competing hypotheses. As regards the latter, he repeatedly emphasises the need to focus on seeking evidence that enables you to reject a hypotheses, rather than looking for confirmation of what you already believe to be true. The section concludes with Heuer’s most significant contribution to practice, a step-by-step process for the “Analysis of Competing Hypotheses”.
The penultimate section of the Book, “Cognitive Biases”, arguably repeats some material that is available elsewhere but, once again, Heuer’s practitioner viewpoint illuminates elements that are not routinely highlighted elsewhere. In particular his discussion of how initial evidence of uncertain accuracy, even if it is subsequently demonstrated to be false, can still colour our judgement is a useful warning to anybody engaged in crisis management; as are his observations on the attention that we pay to the consistency of evidence. Meanwhile the discussion of our endless search for cause-effect relationships and his analysis of people’s interpretations of verbal descriptions of probability are both very relevant to risk management. The concluding chapter, “Improving Intelligence Analysis”, is perhaps less directly relevant to risk and crisis management, but serves well to wrap up the various themes discussed throughout the book.
The 'Psychology of Intelligence Analysis' is a book freely available from the CIA's website. Published in 1999 by Richard J Heuer and the CIA, it's a short read of less than 200 pages and masterfully illustrates complex subjects, such as innate cognitive bias. The book does not pretend to be the definitive topic on intelligence analysis but rather promotes critical thinking, questioning our own conclusions, considering cognitive biases, and looking at uncertainty in a new light. Overall, the book is excellently written and applies to many subjects beyond intelligence gathering, extending itself to all manners of critical thinking. The Psychology of Intelligence Analysis is considered a core work regarding the mind set of an intel analyst and a must read for anyone interested in intel analysis. For that reason I recommend the book to information security analysts who find themselves investigating the human element of computer security. Overall, I give the book 7/10 stars for being free, short and highly thought provoking. This is the type of book that when you are done reading it you don't look at information the same way, but rather take a step back and consider how you are looking at said information in the first place. The book includes a forward by Jack Davis, where he highlights several of Heuer's key philosophies, which I have paraphrased below:
1) Establish an environment that promotes and rewards critical thinking.
2) Promote research on the mental processes involved in shaping analytical judgments. i.e., how do analysts reach judgments?
3) Foster development of tools to assist analysts in assessing incomplete information.
4) Commit to a uniform set of tradecraft standards. Make certain these standards are transparent and self descriptive.
5) Pay honor to "doubt and uncertainty". Encourage multiple working theories.
Like my typical book reviews, I'm now going to cover each chapter and give a breif summary so you may decide if reading the whole book is worth your time:
Chapter 1: Thinking about Thinking
This chapter sets the stage for the entire premises of the book, which is that we must understand and be critical of our own thought patterns that are leveraged in reaching the conclusions we make. That is, we must be self conscious and introspective about our processes of analysis.
Chapter 2: Perception: Why Can't We See What Is There To Be Seen?
This chapter really hammers home that everyone's perception is slanted, whether they want it to be or not. People tend to perceive what they are looking for. One of my favorite quotes from this chapter is: "New Information is assimilated into existing images". Which is to say rather then form new mental models about topics we associate them with mental models we are already familiar with.
Chapter 3: Memory: How Do We Remember What We Know?
This chapter details sensory memory, short term memory, and log term memory. Heuer discusses how as our memory transitions from one state to the next the loss of specific details, deemed unimportant, is the basis for our selective perception.
Chapter 4: Strategies for Analytical Judgment: Transcending the Limits of Incomplete Information
In this chapter Heuer discuses the mental models and approaches we use to arrive at our conclusions. He lays out 4 main strategies situational logic, applied theory, compared with historical data, and data immersion. Each strategy has it's own strengths and weaknesses, which Heuer expands upon in details, before suggesting the development of multiple hypothesis and strategies for choice among them.
Chapter 5: Do You Really Need More Information?
This is one of my favorite chapters because it illuminates some little known facts about how we use information. This chapter asserts that analysts actually make judgments based on only a few pieces of information, and while more information will not increases the accuracy of these judgments it does make the analyst more confident in their decision, which could have adverse effects.
Chapter 6: Keeping an Open Mind
This is another great chapter and a classic fallacy in many investigations. Often analysts will drop or exclude details to a case that they feel don't support their preconceived notions of what happened. Some strategies the book offers are dropping our assumptions and reanalyzing original data sets as if we are seeing them for the first time. The book also promotes multiple competing hypothesis, which should also help view the situation for different perspectives.
Chapter 7: Structuring Analytical Problems
This chapter offers strategies in helping analysts break down and understand problems. It's a good chapter if your looking to break down a complex mental model.
Chapter 8: Analysis of Competing Hypotheses
Analysis of Competing Hypotheses is an 8 step process by which an analyst can attempt to be unbiased in the decision making processes. The steps include: identify possible hypothesis, make a list of significant evidence and how it effects each hypothesis, create a matrix of hypothesis vs evidence, refine the matrix by removing unnecessary data or hypothesis, draw tentative conclusions, remove key evidence supporting those conclusions and see if they still stand, report on all possible hypothesis, and identify milestones for future analysis.
Chapter 9: What Are Cognitive Biases?
This chapter is an overview of cognitive biases, what they are, and how they play out in all of use a little differently.
Chapter 10: Biases in Evaluation in Evidence
This chapter discuses how our perception of information effects the weight we give that information in our cases. That is to say, if it's a first hand experience an analyst will be more likely to draw from that information in their analysis. This chapter also discuses thinking about missing key evidence as well as the confidence and relevancy of information.
Chapter 11: Biases in Perception of Cause and Effect
When making judgments, people often need a cause related to a rational and logical understanding of the situation. Rather than observing events as they are, often analysts will slip into the cognitive bias of assuming they are misunderstanding the situation or are missing key evidence over misunderstanding the cause. Similarly, analysts often look for a unified cause to many desperate events or plan an over-importance on the role of events they are involved in.
Chapter 12: Biases in Estimating Probabilities
This chapter really highlights our many cognitive biases regarding the probability of event based on similar events in our own lives. Similar biases include 'anchoring' or attaching oneself to a logical start of events and being unable to freely conceptualize different scenarios due to needing this logical starting point. Another cognitive bias from this chapter is the analysts desire to go with a familiar explanation when presented with a group of equally uncertain explanations.
Chapter 13: Hindsight Biases in Evaluation of Intelligence Reporting
I thought this chapter was really interesting. It tells how analysts will overestimate the accuracy of their own past judgments and how observers will tend to call such findings 'predictable'. This chapter attempts to outline the different perspectives of the people consuming intelligence reports and how they can put their own cognitive biases down to get the most out of reports.
Chapter 14: Improving Intelligence Analysis
The final chapter gives analysts more of a road map than anything else. It instructs analysts to create through checklists (as to not skip any details due to their own cognitive biases), help define problems, instructions for collecting evidence, strategies for refining competing hypothesis, and even ongoing analysis. It also discuses approaches for management, including training, guidance, and exposing analysts to competing mindsets.
All in all, I thought this book was really enlightening. These are the kind of lessons and approaches to critical thinking that stick with you, things that you can apply to any problem you encounter, and an overall eye opening read! Until next time, enjoy the good reads :)

A great, practical book that truly pushes you to question and improve the way you think and behave. Although it's aimed at intelligence analysts, its insights are useful for a much broader audience. A workbook companion to Kahneman's Thinking, Fast and Slow.
