I think it's important to remember that expertise in one domain doesn't imply expertise in another. It is a bit more broad than that and a recent example was when I bowed out of offering an opinion and explicitly stated that I was unqualified to opine. Their response was that I was smart and they'd value my opinion anyhow. So, it's a two way street and reinforced by external stimuli. In the example case, I'm a mathematician and don't know a damned thing about psychology. My opinions on it should carry no weight and my declination to opine should have signaled that.
