Research indicates that grandiose narcissism is associated positively with self-assessed intelligence (SAI). Furthermore, the direction of possible causation is considered to flow from narcissism to SAI. However, an intriguing question is whether the effect might be reciprocal, that is, whether the belief that one is intelligent facilitates the expression of narcissism. In the current study (N = 364), we investigated this issue by examining how two types of IQ feedback, (1) positive feedback (IQ is above average) and (2) negative feedback (IQ is below average), influenced SAI and a temporary state of narcissistic admiration. Our study revealed that positive IQ feedback correlated with increased people's SAI and one subscale of state narcissistic admiration: striving for uniqueness (i.e., the feeling of being special, bragging about one's abilities and enjoyment of one's successes). By contrast, negative IQ feedback was associated with decreased people's SAI and lower level of state narcissism. We conclude that IQ feedback may shape people's beliefs about their intelligence, and that lay concepts of intelligence might incorporate some narcissistic elements, such as the feeling of being uniquely special.

研究表明，夸大的自恋与自我评估的智力 (SAI) 呈正相关。此外，可能因果关系的方向被认为是从自恋流向 SAI。然而，一个有趣的问题是这种效果是否可能是互惠的，也就是说，一个人是聪明的信念是否有助于自恋的表达。在目前的研究中（N = 364），我们通过检查两种类型的智商反馈（1）正反馈（智商高于平均水平）和（2）负反馈（智商低于平均水平）如何影响 SAI 和暂时的自恋钦佩状态来研究这个问题. 我们的研究表明，积极的 IQ 反馈与人们的 SAI 增加和状态自恋钦佩的一个子量表相关：追求独特性（即感觉自己与众不同、吹嘘自己的能力和享受成功）。相比之下，负 IQ 反馈与人们的 SAI 降低和状态自恋水平降低有关。我们得出结论，智商反馈可能会影响人们对其智力的看法，而外行的智力概念可能包含一些自恋元素，例如独特的感觉。
