No Lights On

The same pattern of results is seen in autistic children, using the parent-report version of the SQ6. Systemizing is also highly correlated with aptitude in science, technology, engineering, and mathematics (STEM)7. Fathers and grandfathers of children with autism are significantly overrepresented in the field of engineering8. The same is true of mothers9. This is in line with higher rates of autism in geographical regions that have higher rates of people working in fields such as information technology, like Eindhoven in the Netherlands10. Further, autistic individuals are more likely to enrol in STEM majors (34.31%) compared to the general population (22.8%) and other learning disabilities (18.6%)11. STEM professionals also score significantly higher on measures of autistic traits (mean = 21.92, SD = 8.92) compared non-STEM professionals (mean = 18.92, SD = 8.48)12. Finally, unpublished work from Sweden suggests that high technical IQ in fathers increases risk for autism in children. A few studies have also investigated systemizing in other psychiatric traits and conditions, including schizotypy13 and anorexia nervosa14.
