Students pursuing STEM degrees (science, technology, engineering, math) were more likely than other students to report having a sibling with an autism spectrum disorder. (Of the 1,077 students who responded to the survey, 16 aspiring technical majors and four aspiring non-technical majors said they had siblings with an autism spectrum disorder.) Additionally, students intending to major in the humanities were more likely to say that they, an immediate family member or their grandparent had been diagnosed with a major depressive disorder, bipolar disorder or substance abuse problems. Intellectual interests, it seems, do have some relationship to mental and neurological disorders.
