Not unexpectedly, the communication styles of these two types of narcissists are completely different. The Potemkin narcissist is sensitive to form, protocol, decorum, and etiquette. He is hypervigilant, constantly on the lookout for signs of disrespect, insults, and slights. He reacts with unbridled rage to any hint of disregard, disagreement, or criticism. The narcissist of appearances is vindictive, holds grudges, and obsessive-compulsive in his reactions to such misconduct and awelessness. In contrast, the narcissist of substance tends to focus on content rather than delivery. He is pragmatic and willing to compromise and reach a consensus. He does not take everything personally and to heart. He bears no grudges and is, usually, not vindictive (though he may be decisive or even punitive).
