But there is a difference between not listening to experience and examining whether the resulting implementation/decisions based on the experience are actually valid. I doubt that someone smart (as you put it) would deliberately want things redone because they don't understand it, that's a trait borne of arrogance not intelligence.

At least in my experience (as a physics grad), me and all my fellow grads are much more likely to apply Chesterton's fence and then make decisions than not doing that and steamrolling existing decisions.
