Narcissism and coldness

…narcissistic people anticipate that success and failure is generally less momentous and (a) assume others are less affected by most success and failure and (b) often feel less happy for successful others and less concerned for unsuccessful others. Findings across three studies were consistent with these propositions. Narcissistic people anticipated that both the self and others will be less reactive to successes and failures (Studies 1–3); moreover, although narcissistic people indicated less warmth toward successful and unsuccessful others, these relations were eliminated after controlling for narcissistic people’s assumptions that other people are less reactive to success and failure (Study 3). Hence, narcissistic coldness could, in part, have its origin in what we believe is reasonable disagreement about the momentous nature of events.

That is from Hart, Tortoriello, and Richardson, via the excellent Kevin Lewis.
