We examined the dimensions people use when estimating their ability to understand personality—an ability we refer to as personal intelligence. In the first two studies (Ns = 434 and 393), a four-factor model fit people's self-estimates reasonably, with scales of the “Explained Self”, “Self-Understanding”, “Understanding Others,” and “Goals and Planning”. In Study 2 and in Study 3 (N = 482) we examined whether any of the specific self-estimated abilities more accurately indexed actual ability-based personal intelligence relative to overall estimates, and if not, what other personality traits they correlated with. To find out, the four factor-based scales of self-estimated abilities were correlated with the objective Test of Personal Intelligence and traits of the Big Five. None of the specific, self-estimated abilities correlated with actual ability any higher than earlier-used experimenter-provided global self-estimated scales; the participants' self-estimates were determined chiefly by dimensions of the Big Five relative to ability, at a ratio of “variance explained” of six to one. The studies provide new insights into how people view their skills at understanding personality, and the possible origins of such beliefs.

我们研究了人们在评估他们理解人格的能力时所使用的维度，这种能力被我们称为“个人智慧”。在前两个研究（Ns  = 434和393）中，四因素模型合理地拟合了人们的自我估计，其尺度为“解释性自我”，“自我理解”，“理解他人”和“目标与计划”。 ”。在研究2和研究3中（N  = 482），我们检查了是否有任何特定的自我估计能力相对于总体估计值能更准确地索引基于实际能力的个人智力，如果不是，则它们与哪些其他人格特征相关。为了找到答案，将基于四个因素的自我评估能力量表与目标相关联。五项个人智力和特质测试。特定的，自我估计的能力与实际能力之间的相关性均不高于早先使用的实验者提供的全局自我估计量表；参与者的自我评价主要由“五巨头”相对于能力的大小决定，“方差解释”的比率为六比一。这些研究为人们如何看待他们在理解人格上的技能提供了新的见解，以及这种信念的可能起源。
