Rationale Thoughts now superseded by timvangelder.com

I have recently produced a combination blog/personal website, http://www.timvangelder.com

The blog on that site supersedes Rationale Thoughts.  All the content from Rationale Thoughts has been moved across.

There will be no more entries here, but the blog will remain available for a while.

Subscribers to this blog may wish to move their subscription to timvangelder.com

What is hypothesis mapping?

1. Hypothesis mapping (HM) is diagramming the thinking involved in hypothesis investigation. Roughly speaking, in HM we draw “box and arrows” diagrams linking our main question (e.g., “Who killed JFK?”) with hypotheses, items of evidence, supporting arguments, etc..  See graphic below.
2. Hypothesis investigation (HI) is determining which hypothesis is “most true” (or most likely to be true) in a given situation.  It includes generating adequate hypothesis sets, hypothesis evaluation (assessing relative plausibility of hypotheses given the evidence), and hypothesis testing (determining what evidence to obtain in order to conduct proper evaluation).
3. HM is an aid to diagnostic judgment.  In a simple tripartite classification of judgments, diagnostic judgment is addressing the question “What is going on?” (or “What will be going on?”)  Diagnostic processes attempt to ascertain “how things are” based on available or obtainable evidence.   (More questions which help convey what diagnostic judgement is for: What is happening? What is the problem?  What is the cause? What are they thinking? What is their strategy?)
4. HM makes the thinking involved in HI visual, and is thus able to exploit the massive processing power of our visual systems.
5. HM imposes structure on the thinking involved in HI, by requiring that information be classified and positioned on the map.
6. HM, when done properly, imposes discipline on the HI process.  There are rules or guidelines to be followed; there is expertise to be acquired.  HM can be done badly or it can be done well.  Doing it well requires understanding and observing the rules.
7. Hypothesis mapping, when done competently, promises a number of advantages relative to typical, ad hoc or informal approaches to HI.  Most importantly, it promises to improve one’s “hit rate” in HI, i.e. help you be more right more often in the conclusions you draw about what is going on.  It also aids in making the HI process more efficient and rigorous, sharing the thinking behind HI within a team, and making conclusions more defensible and accountable.
8. HM is a general purpose method.  It can be used in just about any domain – medicine, engineering, science, business, etc. etc.
9. However HM is particularly relevant to intelligence analysis.  HM should be seen as a new addition to the intelligence analyst’s toolkit.
10. As such, HM is an alternative to the well-known Analysis of Competing Hypotheses (ACH) method.  Of course somebody might want to use both methods, HM for some problems and ACH for others, or as two different frameworks for approaching the same problem.
11. HM and ACH have complementary strengths and weaknesses.  Fundamentally, HM is based on hierarchical structure, while ACH is based on matrix or table structure.  Both share the insight that bringing rigor to thinking about hypotheses requires conforming that thinking to explicit external (“outside the mind”) structures.  Any given type of structure will have certain advantages, but also certain costs.  The expert practitioner will be able to use the most appropriate tool for the task, with awareness and depth understanding of the strengths and weaknesses of the tool.
12. Arguably, some of the advantages of HM over ACH – particularly its more intuitive character, and more attractive visualisation – will lead to HM displacing ACH as the default tool for HI in intelligence.
13. HM, when done in a sophisticated fashion, involves the detailed articulation and assessment of arguments, and so draws on argument mapping.  In particular, HM cannot be done with full rigor without proper appreciation of the role of co-premises in argument structures.
14. The best way to do HM is to use software designed to support HM activities.  bCisive 2 is currently the leading software for HM (as well as decision mapping and argument mapping).
15. Austhink Consulting, which has been pioneering hypothesis mapping, provides training, facilitation and consulting services in HM.

Bouquets appreciated

I’ve been engaged (with a great team) in building argument mapping software for over a decade now.  Its been an uphill battle most of the way.  The acid test of success is sales, but there are other measures, such as positive, insightful feedback from users who “get it,” i.e. understand what we’ve done.  Such as the feedback which arrived today:

“I could go on at length about how much I like Rationale.  Where to start.  Where it end.  First of all a big sincere thanks to the designers – developers.  Your product is superlative.  It functions flawlessly, doesn’t crash, no small accomplishment.  The conceptual method of Rationale diagramming is really great.  It is easy and fun to use.  If more readers were aware of the methodology gently introduced in Rationale’s tutorials, they would reach more intelligent conclusions and be more demanding of writers.  I am just starting the final exercise sets in Rationale.  They appear to have a pretty good dose of philosophy, a fair stretch made easy by your excellent tutorials. Rationale is a truly different, truly useful product.”
