I tend to agree with this but I also think that a knowledgeable person should be eager to stand his or her ground and probably will on subjects that matter dearly to them. For instance you might be able to convince a scientist of a philosophical viewpoint, but they might never budge from their stance on a scientific view point and in turn adamantly defend its idea with an almost righteous conviction (e.g. Richard Dawkins). But I guess we should be truly happy about this effect. If the smart amongst us were brow beating us all constantly it would be very painful indeed. I know I'd be a ripe target.
