Steve, I'm surprised you didn't find any posts by me in your search for "causality" . Usually, when someone says "correlation is not causation" it triggers me. In the early 90s/late 80s there were two teams working on inference of causal graphs from observational data: Pearl et al at UCLA and Glymour et al at Carnegie Mellon. They cooperated and developed algorithms based on d-separation which was based on conditional independence relations (correlation). Glymour et al's book is "Causation, Prediction and Search". I implemented many algorithms in Java for that group over a period of about 10 years and I was co-author of several papers.
