I like that—probably a good rule of thumb, although it a stock-picker starts off saying they’re a contrarian, I wouldn’t necessarily stop listening. I’d also be more specific and say that labeled “contrarian” in an approving way by someone I trust might be worth paying attention to.
But rules of thumb aren’t meant to be so wordy, so I still like yours.
I’m extremely intellectually compulsive if I do say so perhaps immodestly; just for example, I read a lot of books by people I expect to disagree with, and in fields I start out with no clue about; but I’m trying to get better and better at knowing where to draw the line—and to share some of thoughts on on this in part so they can be criticized.
Well, here I am, still interacting with you. Maybe my kung fu is being beaten, maybe not (by the way, sadly, David Carradine died a few years back in a Bangkok hotel of asphyxiation—at least that’s what Wikipedia says—I looked it up because I had the notion maybe it was very recent. I used to like Kung Fu, but then when Carradine became such an action/adventure B actor, I was disillusioned—such are the follies of youth).
