“I’m not qualified to have an opinion on a subject unless I can state the arguments against my position better than the people do who are supporting it. I think that only when I reach that stage am I entitled to speak.” ~ Charlie Munger ¹

This quote is so good, it hardly needs a commentary.

What are the subjects about which I am not qualified to have an opinion?

What if we only considered advice from people who have a qualified opinion in their areas of expertise? How would agronomy and agriculture be different?
