The health crisis caused by COVID-19 has led many countries to opt for social quarantine of the population. During this quarantine, communication systems have been characterized by disintermediation, the acceleration of digitization and an infodemic (excess and saturation of information). The following debate arises: Do the levels related to the psychotic phenotype and pseudoscientific beliefs related to the interpretation of information vary before and after social quarantine? This research aims to examine the psychological effects of social quarantine on the psychotic phenotype and pseudoscientific beliefs-experiences of the general nonclinical population. The following hypothesis was posed: social quarantine alters the levels of magical thinking, pseudoscientific beliefs and anomalous perceptions due to quarantine. A pre- and posttest analysis design was applied based on the difference in means, and complementary Bayesian estimation was performed. A total of 174 Spanish subjects responded to different questionnaires that evaluated psychopathological risks based on psychotic phenotypes, pseudoscientific beliefs and experiences before and after quarantine. Significant differences were obtained for the variables positive psychotic symptoms, depressive symptoms, and certain perceptual alterations (e.g., cenesthetic perceptions), and a significant increase in pseudoscientific beliefs was also observed. The perceptual disturbances that increased the most after quarantine were those related to derealization and depersonalization. However, paranoid perceptions showed the highest increase, doubling the initial standard deviation. These high increases could be related to the delimitation of physical space during social quarantine and distrust towards information communicated by the government to the population. Is it possible that social alarmism generated by the excess of information and pseudoscientific information has increased paranoid perceptual alterations? Measures taken after quarantine indicate that perceptual disturbances, subclinical psychotic symptoms and beliefs in the pseudoscience have increased. We discuss which elements of quarantine coincide with the social marginality theory and its clinical repercussions.

COVID-19 社会隔离后，伪科学信念和精神病理学风险增加。

COVID-19 引发的健康危机导致许多国家选择对民众进行社会隔离。在隔离期间，通信系统的特点是脱媒、数字化加速和信息流行病（信息过剩和饱和）。出现以下争论：与信息解释相关的精神病表型和伪科学信念的相关水平在社会隔离之前和之后是否有所不同？本研究旨在研究社会隔离对一般非临床人群的精神病表型和伪科学信念体验的心理影响。提出了以下假设：社会隔离改变了隔离引起的神奇思维、伪科学信仰和异常认知的水平。根据均值差异应用测试前和测试后分析设计，并进行补充贝叶斯估计。共有 174 名西班牙受试者回答了不同的问卷，这些问卷根据精神病表型、伪科学信念和隔离前后的经历评估了精神病理学风险。阳性精神病症状、抑郁症状和某些知觉改变（例如，幻觉知觉）等变量获得了显着差异，并且还观察到伪科学信念的显着增加。隔离后增加最多的知觉障碍是与现实解体和人格解体相关的知觉障碍。然而，偏执观念的增幅最高，是初始标准差的两倍。这些高增长可能与社会隔离期间物理空间的划分以及对政府向民众传达的信息的不信任有关。过多的信息和伪科学信息所产生的社会危言耸听是否有可能增加了偏执的感知改变？隔离后采取的措施表明，知觉障碍、亚临床精神病症状和对伪科学的信仰有所增加。我们讨论了隔离的哪些要素与社会边缘理论及其临床影响相一致。
