Research on the personality foundations of aggression typically implicates either (a) aspects of the so-called “Dark Tetrad” or (b) severe mental disturbance (psychosis). The appearance of psychotic symptoms in general populations is termed schizotypy. We conducted two studies to compare the effects of dark personalities and schizotypy on aggression. Study 1 used standard inventories to investigate the overlap of Dark Tetrad traits with schizotypy in a sample of 977 undergraduates. All tetrad traits except narcissism were positively associated with schizotypy, but only at moderate levels. Study 2 administered the same personality battery to 303 members of an online community sample: Aggression outcomes were measured with both self-reports and a behavioral measure—the Voodoo Doll Task. Regression analyses determined the unique contributions of the five personality variables. Two dark traits—psychopathy and sadism—were strong predictors of self-report aggression. Schizotypy added incrementally to the Dark Tetrad in predicting both self-report and behaviorally measured aggression.

黑暗还是不安？：预测来自黑暗四分体和分裂型的侵略

对攻击性人格基础的研究通常涉及 (a) 所谓的“黑暗四分体”或 (b) 严重的精神障碍（精神病）。在一般人群中出现精神病症状称为分裂型. 我们进行了两项研究来比较黑暗人格和分裂型对攻击性的影响。研究 1 使用标准清单来调查 977 名本科生样本中暗四分体特征与分裂型的重叠。除自恋外的所有四分体特征都与分裂型呈正相关，但仅处于中等水平。研究 2 对在线社区样本的 303 名成员进行了相同的人格测试：攻击性结果通过自我报告和行为测量（巫毒娃娃任务）进行测量。回归分析确定了五个人格变量的独特贡献。两个黑暗特征——精神病态和虐待狂——是自我报告攻击性的​​强烈预测因素。Schizotypy 在预测自我报告和行为衡量的攻击性方面逐渐添加到 Dark Tetrad 中。
