Notes de l'éditeur
- Richards Heuer is the author of Psychology of Intelligence Analysis. Heuer spent 45 years gaining experience in intelligence and security working for the Central Intelligence Agency (CIA). In addition to publishing work on the psychology of intelligence analysis, he also published works on counterintelligence, deception, analytical methodologies, and personnel security issues.
- The scientific method is a proven process based on the rejection of hypotheses in which the analyst accepts only those which are not disproven. Traditional intelligence analysis does not seek to refute hypotheses, but tends to seek confirmation of initial judgments. Cognitive biases are mental errors caused by simplifying information processing strategies. Emotional or intellectual predispositions toward certain judgments do not cause cognitive biases; rather, cognitive biases are the result of subconscious mental shortcuts for processing information.Analysis of Competing Hypotheses ACH assists analysts in identifying and questioning basic assumptions providing a means to test hypotheses. ACH is an eight-step procedure that allows analysts to leave an audit trail, unlike other decision-making processes. In order to prevent distortions caused by cognitive biases, Heuer’s method requires analysts to explicitly identify all reasonable hypotheses. Hypotheses compete for the analyst’s favor, eliminating satisficing because the analyst is working with all possible rational hypotheses. Typically, analysts identify what appears to be the most promising hypothesis before collecting and organizing information based on whether it supports or refutes the hypothesis the analyst has chosen. Often incongruent information is not fully exploited, nor are other hypotheses tested. When testing one hypothesis at a time, biases and mindsets are harder to dispel.
- AuditableWith ACH, analysts note all evidence and hypotheses on paper, making the path from collection to final estimate easier to follow.Overcomes cognitive biasesIndividually analyzing each piece of evidence can give analysts a skewed view of the overall picture. Using ACH, disproving hypotheses provides a more effective method for avoiding established mental roadblocks.LogicalThe competitive aspect of ACH forces analysts to examine hypotheses more logically than separating them for reviewing one at a time.ACH is similar to Multi-Criteria Decision Making (MCDM).Although ACH is more effective than less-systematic, traditional approaches, no process is without drawbacks.Snapshot in timeThe evidence used in the analysis is static, while events are dynamic. In order to provide a timely analytic product, analysts must determine a point at which to halt collection in order to prepare the estimate. Dependent on validity of evidenceAnalysis is only as good as the evidence that goes into the process. Unreliable evidence can undermine even the most thoughtful process execution. As evidence can be ambiguous and prone to the pitfalls of deceptive tactics, it is difficult to determine reliability and validity of the inputs. No better than the skill of the analyst using the processThe degree to which ACH can reduce cognitive biases reflects the skill of the analyst using it. A successful analyst must be imaginative when generating hypotheses, keeping his mind open to all possibilities, rather than attempting to anticipate an outcome before examining the evidence. He must also carefully weigh the reliability and relevance of the evidence.Time consumingPerforming the ACH process manually can be long and arduous, especially when there are numerous hypotheses and a large body of evidence. Due to the amount of time that it takes to do this by hand and the time pressures analysts usually encounter, they do not apply the method as often as might be appropriate. For this reason, automation of ACH is critical and will be discussed in the next lesson.
- Structure is provided by delving deeper into the previous hypothesis and further exploiting the evidence, or gathering more.Automation, and structure with PARC Software facilitates the analysis of the second level of hypothesis testingIn other words, structure enables analysis of complex problems consisting of several questions by deconstructing the complex question into simple questions with either yes, no answers or mutually exclusive answers. Then ACH is applied to the root question, and the remaining questions are added to the winning hypothesis and ACH is applied again. (Added by NSA, 1Sep06)
- Using SACH eases the process for analysts from start to finish. SACH closes evidence gaps, creating a tighter finished product.Documenting every step in SACH later helps analysts easily follow the estimative process. Because SACH provides a trail of auditable information, should the analyst provide an incorrect estimate, it is easier to evaluate what went wrong.In conclusion:SACH allows analysts to coordinate which evidence to test with the hypotheses the analyst is testing. It also allows the analyst to deal more effectively with large amounts of evidence.SACH assists managers in supervising and monitoring analysts’ progress.SACH provides decisionmakers with higher-quality products, and makes it easier for them to see exactly how the analyst arrived at the final estimate. When presenting to decisionmakers, analysts will more effectively produce documents with the bottom lines up front (BLUF) because the automation of SACH helps analysts discover and prove the bottom line.SACH improves oversight, as products are more easily defendable by clearly tracing all thought processes back to the original evidence.
- The software takes an analyst through a process for making a well-reasoned, analytical judgment. Usefulfor issues that require weighing of alternative explanations of what has/is/or may happenIt helps the analyst overcomesome cognitive limitations that make prescient intelligence analysis difficult. ACH is grounded in psychology, decision analysis, and the scientific method. It helps analysts protect themselves from avoidable errorImproves their chances of making a correct judgment
