The big picture: Statistical Significance vs Policy Importance
Is an association detectable, important, or both?
Why a policy analyst should care
A precisely estimated trivial difference and an imprecisely estimated consequential difference pose different policy questions that a significance label cannot resolve.

2 Explore Same effect, different evidence
3 Formalize Two separate judgments
4 Transfer Make a policy judgment
