Full Idea
Deduction models of explanation make it far too easy to explain. You can explain that planets move in an ellipse from the conjunction of the fact that they do, together with any law you please, say a law in economics.
Gist of Idea
Deduction explanation is too easy; any law at all will imply the facts - together with the facts!
