The concept of inferential distance suggests to me that posts should try and make their pathways as short and straight as possible. Why write a double-length post that explains both causal models and metabolism, when you could write a single-length post that explains only causal models? (And, if metabolism takes longer to discuss than causal models, the post will mostly be about the illustrative detour, not the concept itself!)

You've convinced me. I now agree that EY should go back and edit the post to use a different more conventional example.
