Abstract

Humans infected by Toxoplasma gondii express no specific symptoms but manifest higher incidence of many diseases, disorders and differences in personality and behavior. The aim of this study was to compare the political beliefs and values of Toxoplasma-infected and Toxoplasma-free participants. We measured beliefs and values of 2315 responders via an online survey (477 Toxoplasma-infected) using the Political Beliefs and Values Inventory (PI34). This study showed Toxoplasma-infected and Toxoplasma-free participants of our cross-sectional study differed in three of four factors of PI34, scoring higher in Tribalism and lower in Cultural liberalism and Anti-Authoritarianism. We found sex differences in political beliefs associated with Toxoplasma infection. Infected women scored higher in tribalism and lower in cultural liberalism, compared with the Toxoplasma-free control group, while infected men scored higher in economic equity. These results fit with sexual differences in behavior and attitude observed after toxoplasmosis infection. Controlling for the effect of worse physical health and mental health had little impact, suggesting that impaired health did not cause these changes. Rather than adaptation to prevalence of parasites, as suggested by parasite-stress theory, the differences might be side-effects of long-term mild inflammatory reaction. However, to get clear picture of the mild inflammation effects, more research focused on different infectious diseases is needed.

小马基雅维利王子:潜伏弓形虫病对政治信仰和价值观的影响。
感染弓形虫的人没有特定的症状,但表现出许多疾病、障碍的发病率较高,性格和行为也有所不同。本研究的目的是比较弓形虫感染和未感染弓形虫的参与者的政治信仰和价值观。我们通过使用政治信仰和价值观量表(PI34)进行在线调查(477名弓形虫感染者),测量了2315名响应者的信仰和价值观。本研究显示,我们横断面研究的弓形虫感染者和未感染弓形虫的参与者在PI34的四个因素中有三个存在差异,部落主义得分较高,文化自由主义和反威权主义得分较低。我们发现政治信仰的性别差异与弓形虫感染有关。与未感染弓形虫的对照组相比,感染弓形虫的女性在部落主义方面得分较高,在文化自由主义方面得分较低,而感染弓形虫的男性在经济公平方面得分较高。这些结果与弓形虫感染后行为和态度的性别差异相吻合。控制身体健康和精神健康状况恶化的影响几乎没有影响,这表明健康受损并不是导致这些变化的原因。正如寄生虫应激理论所指出的那样,这些差异可能是长期轻度炎症反应的副作用,而不是对寄生虫流行的适应。然而,为了清楚地了解轻微的炎症效应,需要更多的研究集中在不同的传染病上。
