HOW ARE THE BRAINS OF PSYCHOPATHS DIFFERENT?
(a) Lower grey matter and lower white matter density in the orbitofrontal cortex and anterior insula. (common in all antisocial behavior). IMO the cause.
(b) Decreased size of empathy and moral reasoning regions (ventromedial prefrontal cortex, orbitofrontal cortex). IMO probably a consequence.
(c) Larger striatum (cognition, motor, action planning, decision making) Common in egotistical and antisocial behaviors. IMO a consequence.

Suggests late stage failure of development and as such retention of pre-modern human cognitive features of the brain. (Failures of domestication syndrome). So where autism is a property of compartmentalization, and psychosis a failure of compartmentalization, similarly, it appears that common female misplaced empathy (which is endemic) is mirrored by absence of empathy (sociopathy/psychopathy).

So just as there is value to the autism spectrum and the solipsistic spectrum, there is value to the sociopathy and misplaced empathy spectrum.

Nature doesn’t so much have a recipe as evolution explores the limits until it finds one some way to benefit by crossing them.

IMO the autistic spectrum is as deterministic an evolutionary outcome as is consciousness. it’s the direction of human evolution.
