Mind blame

Nobel Prize winning neuropsychiatrist writes an op-ed for the NY Times "The New Science of Mind" about the biology of mental disorders. He first uses the example of how psychotherapy and anti-depressant pharmaceuticals both change the structure and functioning of the brains of depressives, but one works better than the other depending on the neurological roots of the patients' depression. He also uses the genetic example of how an extra copy of genetic sequence means an increased risk of autism and its accompanying anti-social tendencies or a missing copy of the same sequence leads to Williams syndrome and its accompanying intense sociability.

Our understanding of the biology of mental disorders has been slow in coming, but recent advances like these have shown us that mental disorders are biological in nature, that people are not responsible for having schizophrenia or depression, and that individual biology and genetics make significant contributions.

The result of such work is a new, unified science of mind that uses the combined power of cognitive psychology and neuroscience to examine the great remaining mysteries of mind: how we think, feel and experience ourselves as conscious human beings.

This new science of mind is based on the principle that our mind and our brain are inseparable. The brain is a complex biological organ possessing immense computational capability: it constructs our sensory experience, regulates our thoughts and emotions, and controls our actions. It is responsible not only for relatively simple motor behaviors like running and eating, but also for complex acts that we consider quintessentially human, like thinking, speaking and creating works of art. Looked at from this perspective, our mind is a set of operations carried out by our brain. The same principle of unity applies to mental disorders.

In years to come, this increased understanding of the physical workings of our brain will provide us with important insight into brain disorders, whether psychiatric or neurological. But if we persevere, it will do even more: it will give us new insights into who we are as human beings.

Like most other mental disorders, sociopaths are characterized by both genetic and neurological differences that distinguish them from neurotypicals. I'm not saying that sociopaths aren't responsible for their actions, but they're certainly not responsible for being sociopaths.
