Quotable: Harvard Mental Health Letter

"[P]sychopathy is not simply the effect of certain social environments or cultural values. Middle- class men and women raised in sober, law-abiding, two-parent families are not immune to it....

[S]ome people may be genetically vulnerable to psychopathy. Antisocial personality is common in the fathers of both male and (especially) female sociopaths. The concordance (matching) rate for sociopathy in genetically identically twins is estimated at nearly 50 percent-two or three times higher than is found in fraternal twins."
