A fifteen-minute overview
Psychology of
Intelligence Analysis
Heuer’s argument is that the limiting factor in analysis is not the supply of information but the mind that processes it — and that the mind builds the very models through which it reads the evidence.

The book collects articles Heuer wrote between 1978 and 1986 for the CIA Directorate of Intelligence, revised and published as a monograph in 1999 (Author’s Preface, p. vii). It is no history of intelligence failures and teaches no collection tradecraft. It reports what cognitive psychology had established about how people judge incomplete and ambiguous information, translated for the people whose job that is.
The uncomfortable finding underneath it is that expertise offers no protection. Douglas MacEachin, a former CIA Deputy Director of Intelligence, puts it plainly:
“the pitfalls the human mental process sets for analysts cannot be eliminated; they are part of us”
One page per part, in reading order, plus a page on the tool the book is best known for. Each closes by naming the chapter to open first. With five minutes rather than fifteen, read Part III and then the checklist.
Analysis of Competing Hypotheses takes Chapter 8 on its own; the chapter map lists all fourteen chapters with their page numbers. This site summarizes and quotes the book; it does not reproduce it — see About & provenance.
