Except I'm not sure iwho's that bothered that those whose job is offering opinions keeping saying different things on different days.

I've more than once read an opinion-former make two mutually-contradictory opinions in the same piece!!

I'll take the liberty of repeating "How do you know when you're ill-informed?"

I know I am. One answer can be,"When you're challenged."; another,"When your plans fall flat."

The question then becomes,"How do you know you're ill-informed before either of those things happen?"
