Researchers have long noted higher rates of schizophrenia among immigrants, although it's not clear why this is the case. One possibility is that there is something about the process of migration itself that causes increased rates of schizophrenia. Another possibility, referred to as selective migration, is that people who are predisposed to schizophrenia are more likely to migrate. Multiple recent publications have denied that selective migration plays a role in explaining increase rates of schizophrenia among migrants. We challenge this claim, reviewing evidence that positive schizotypy, a longitudinal predictor of psychosis, is associated with an increased tendency towards exploration. We hypothesize that this increased exploration also results in an increased tendency to migrate. We present the results of a pre-registered study (N = 235) showing that positive schizotypy uniquely predicts migration intentions/desires when all three schizotypy factors are included in a regression.

长期以来，研究人员一直注意到移民中精神分裂症的发病率较高，但尚不清楚为什么会这样。一种可能性是，迁移过程本身会导致精神分裂症发病率增加。另一种可能性，称为选择性迁移, 是易患精神分裂症的人更容易迁移。最近的多篇出版物否认选择性移民在解释移民中精神分裂症的发病率增加方面发挥了作用。我们质疑这一说法，审查阳性分裂型（精神病的纵向预测因子）与探索倾向增加相关的证据。我们假设这种增加的探索也会导致迁移趋势的增加。我们展示了一项预先注册的研究 ( N  = 235)的结果，表明当所有三个分裂型因素都包含在回归中时，阳性分裂型可以唯一地预测迁移意图/愿望。
