One could be wrong despite the right reasoning or right for the wrong reasons.
And yet, at some level, I agree with you. It's natural to weight what other people say by perception of their prior predictions. I have a similar reaction to Larry Kudlow or Jim Cramer: if one of them told me the sky was blue, I would have to go outside and double check.
Thinking about it some more, I think I can reconcile the difference by looking at the reasoning versus looking at the result. Like poker: you can make the right move and still lose, or make the wrong move and still win.
To bring that back to the current topic: Trump may yet escape causing a recession, but the reasoning for "this tariff war is a terrible idea" has thus far struck me as a lot more coherent than the reasoning for "this tariff war will lead to prosperity"
