Emotional problems like depression, anxiety and bipolar disorder, seen through this lens, appear on Mom's side of the teeter-totter, with schizophrenia, while Asperger's syndrome and other social deficits are on Dad's.
It was Dr. Badcock who noticed that some problems associated with autism, like a failure to meet another's gaze, are direct contrasts to those found in people with schizophrenia, who often believe they are being watched. Where children with autism appear blind to others' thinking and intentions, people with schizophrenia see intention and meaning everywhere, in their delusions. The idea expands on the ''extreme male brain'' theory of autism proposed by Dr. Simon Baron-Cohen of Cambridge.
I think we all fall on this spectrum. If we're lucky, we fall somewhere in the middle: stable, adaptable, and emotionally competent. But I love the idea that sane/insane, balanced/imbalanced, etc. are false binaries (flashback to freshman english class, deconstructing the three sisters from King Lear!) Just like my politics, I'm slightly left-of-center: Socially awkward, better at analyzing than reacting emotionally in the present.
