CIA Dr Richards J. Heuer: “Information Collection vs Analytical Methods”

“Do You Really Need More Information? The US Intelligence Community invests heavily in improved intelligence collection systems while managers of analysis lament the comparatively small sums devoted to enhancing analytical resources, improving analytical methods, or gaining better understanding of the cognitive processes involved in making analytical judgments.”

Accurate intelligence judgments do not solely rely on the abundance and accuracy of the information. Indeed it has long been known that rigorous analysis of the information is at least as important as the gathered material in order to reach accurate intelligence estimates.

In the 1960s, CIA psychologists investigated the correlations between the amount of information available to experts, the accuracy of their judgments, and the experts’ confidence in the accuracy of these judgments. The results of these experiments are far-reaching.

Confidence & Accuracy vs Information

Confidence & Accuracy vs Information

In one of these experiments, experienced horserace handicappers were shown a long list of variables that included data related to the recent performances of the horses, the weight of the jockeys, the time since the last race, the weather conditions, etc. Each handicapper was asked to order these variables according to its perceived importance in the making of his prediction.

Next the handicappers were shown real data that had been renamed to ensure that they could not remember the events. Each of them was then given the five variables he had listed as the most useful. At that point they were asked to make a prediction as well as an estimate of the degree of accuracy of his prediction (from 0% to 100%). The same exercise was repeated after the handicappers were given 10, 20 and 40 variables.

The result of this particular experiment is abundantly clear. On one hand the accuracy of the prediction did not improve with additional information. As a matter of fact, several handicappers tended to be less accurate as more information became available to them.

On the other hand, their confidence in the accuracy of their predictions increased significantly as they were provided with more information. (See figure above.)

Note that only when provided with the lowest amount of information were the handicappers realistic about the probability of their predictions being correct.

Key findings from these experiments:

Once an experienced analyst has the minimum information necessary to make an informed judgment, obtaining additional information generally does not improve the accuracy of his or her estimates.

Additional information does, however, lead the analyst to become more confident in the judgment, to the point of overconfidence.

Experienced analysts have an imperfect understanding of what information they actually use in making judgments.

They are unaware of the extent to which their judgments are determined by a few dominant factors, rather than by the systematic integration of all available information.

Analysts actually use much less of the available information than they think they do.

About Richards “Dick” J. Heuer

Richards “Dick” J. Heuer, Jr. is a former CIA veteran of 45 years and most known for his work on analysis of competing hypotheses and his book, Psychology of Intelligence Analysis. The former provides a methodology for overcoming intelligence biases while the latter outlines how mental models and natural biases impede clear thinking and analysis.

Throughout his career, he has worked in collection operations, counterintelligence, intelligence analysis and personnel security. In 2010 he co-authored a book with Randolph (Randy) H. Pherson titled Structured Analytic Techniques for Intelligence Analysis.

Richards Heuer is well-known for his analysis of the extremely controversial and disruptive case of Soviet KGB defector Yuri Nosenko, who was first judged to be part of a “master plot” for penetration of CIA but was later officially accepted as a legitimate defector. [Wikipedia]

About the Analysis of Competing Hypotheses

“Analysis of competing hypotheses (ACH) is an analytic process that identifies a complete set of alternative hypotheses, systematically evaluates data that is consistent and inconsistent with each hypothesis, and rejects hypotheses that contain too much inconsistent data.”

ACH is an eight step process to enhance analysis:

  1. Identify all possible hypotheses
  2. Make a list of significant evidence and arguments
  3. Prepare a matrix to analyze the “diagnosticity” of evidence
  4. Drawn tentative conclusions
  5. Refine the matrix
  6. Compare your personal conclusions about the relative likelihood of each hypothesis with
  7. the inconsistency scores
  8. Report your conclusions
  9. Identify indicators

Heuer originally developed ACH to be included as the core element in an interagency deception analysis course during the Reagan administration in 1984 concentrated on Soviet deception regarding arms deals.

The Palo Alto Research Center (PARC) in conjunction with Heuer developed the PARC ACH 2.0.5 software for use within the intelligence community in 2005.


This experiment is described in a book published on the CIA website:
