There are two tags causality and causal-inference that seem identical or at least closely related -- aren't they? Reviewing the posts tagged by both tags shows that there is not much difference between them. Maybe they should be merged?
When I read your question I first wanted to comment pointing out a possible difference in meaning between these two tags.
But then I looked at what questions are tagged with each of them, and I actually see no difference at all. It's a mess! Given this random usage, I agree that the tags should better be merged.
Even though the second tag has many more threads, most of them are actually about "causality" in general and not about some specific inference procedures. I have written a brief wiki excerpt for
[causality], so the merge is ready to go.
