The career
Recruited by the Central Intelligence Agency in 1951 while a graduate student at Berkeley, Heuer worked across operations, counterintelligence, analysis, and personnel security over 45 years.
The name
The name behind R6I
One analyst, one hard lesson about evidence, and six lenses.
R6I is Richards Six Investigations. Richards is Richards J. Heuer Jr., the CIA analyst who spent his career on why capable people reach wrong conclusions from good evidence. The six is the number of lenses in the framework that first carried his name.
The namesake
Richards J. Heuer Jr., 1927 to 2018.
The book
Psychology of Intelligence Analysis, published by the CIA in 1999, examines why capable analysts reach wrong conclusions. It is still used to train analysts today.
The method
His Analysis of Competing Hypotheses forces every plausible explanation to be tested against the evidence, with particular weight on the evidence that does not fit.
The legacy
With Randolph Pherson he codified structured analytic techniques in a 2010 field guide that is now taught across the intelligence community and used well beyond it.
His work is public: Psychology of Intelligence Analysis and the agency's memorial note on his life (PDF) are both available from the CIA's Center for the Study of Intelligence.
The lesson
Good evidence, read badly, still fails.
In 1964 a KGB officer named Yuri Nosenko defected to the United States, and the CIA spent years divided over whether he was genuine or a plant. Heuer's study of the case, Nosenko: Five Paths to Judgment, explains how careful people got it wrong.
What went wrong
- Analysts committed early to a single hypothesis
- New facts were read through the view already held
- Evidence that fitted was collected and counted
- Evidence that did not fit was explained away
What Heuer taught instead
- Set out every explanation the evidence could support
- Include the unwelcome explanations
- Hunt for the material that would disprove each one
- Keep the conclusion that survives
A conclusion earns its place by surviving the attempt to knock it down, not by arriving first. That sentence is the whole reason his name is on this practice.
The six
The number came before the practice.
The name predates the investigations work. Before this practice existed, I built an analytical framework on Heuer's structured techniques and named it for him: Richards Six. Every assessment it produced examined the same decision through six lenses.
-
01
Key assumptions
Every assessment opened with a register of the assumptions the decision rested on, because an unstated assumption is the first place a judgement fails.
-
02
Attack vectors
Where the plan could be attacked: the pressures, incentives, and actors most likely to break it, identified before they had the chance.
-
03
Competing hypotheses
Heuer's own method, applied directly. Every plausible explanation was tested against the evidence, with attention on what each explanation could not account for.
-
04
Pre-mortem
The decision was assumed to have already failed, then reconstructed backwards to find the most likely causes of that failure.
-
05
Decision triggers
The specific, observable events that should force the conclusion to be revisited, stated in advance rather than recognised in hindsight.
-
06
Blind spots
What the analysis itself could not see, stated plainly rather than left for the reader to discover.
That framework is history, not a current service, and its six lenses are not a package this practice applies to workplace investigations. The six carried over as provenance: a reminder, built into the name, that a question deserves more than one way of looking before anyone settles on an answer.
What carries over
The discipline, not the packaging.
Questions first
The questions that need answering are settled before evidence is gathered, so the evidence is tested against the scope rather than a preferred outcome.
Fair testing
People affected by adverse material get a genuine chance to respond, and material conflicts in the accounts are examined rather than smoothed over.
Shown reasoning
The report explains how each finding was reached and says plainly what the evidence will and will not support.
