Abstract
This study investigated whether individuals with a high genetic risk for schizophrenia but without non-affective psychotic disorders exhibit increased magical thinking. Using data from the Young Finns Study (n=1292), the researchers calculated polygenic risk scores (PRS) for schizophrenia and assessed magical thinking using the Spiritual Acceptance Scale. Results showed that high PRS predicted higher magical thinking in adulthood, particularly in middle age, even after controlling for various factors. This suggests that a high genetic risk for schizophrenia may manifest as milder forms of deviant thinking in individuals who do not develop the full-blown disorder.
