ABSTRACT
Are psychopaths born or made? Robert Hare (personal communication, January 2000) told me this question was akin to attempting to describe a soccer field by its length or its width; both dimensions are necessary to capture the expanse, or expansive personality, that we see before us. When this question is posed to me by others, I point out that the more realistically based question is how nature and nurture shape each other over time, since a child comes into the world with a certain genotype that is phenotypically expressed according to the vagaries of personal experience.
