Disproving the claim that this particular person is behaving in this way because of these brain structures is nearly impossible with the state of neuroscience as it currently is, so it isn't a something that can be viewed as anything other than an interesting hypothesis at this stage. You just wouldn't be able to achieve anything approaching a decent level of statistical confidence from studying a single subject, no matter how many anecdotes you cite about them.

The standard of proof, and things you're expected to cite as evidence, is very different for "this particular person is a psychopath" vs "psychopaths in general have this characteristic".

>You just wouldn't be able to achive anything approaching a decent level of statistical confidence from studying a single subject, no matter how many anecdotes you cite about them.

Therefore, no one can be found guilty of murder beyond a reasonable doubt given that it's "just one person"?

[moocowduckquack]

you are confusing the legal with the scientific process, they are not the same thing

[SilasX]

No, you are. You're bringing up scientific standards of proof that are totally inapplicable to the question of whether one person meets the diagnostic criteria. Your argument would likewise "prove" that therapists can't diagnose patients with anything because they "only have anecdotal evidence" about "one person".

Yes, someone is very confused here and wasting people's time, but it's not me.

It's not every day that I hear someone argue that scientific standards aren't applicable to an issue potentially resolvable with science.

> Your argument would likewise "prove" that therapists can't diagnose patients with anything because they "only have anecdotal evidence" about "one person".

But that is true, and it's been proven over and over again. Psychologists cannot reliably diagnose mental illnesses -- this is a matter of public record and scientific evidence. Tom Widiger, who served as head of research for DSM-IV, says, "There are lots of studies which show that clinicians diagnose most of their patients with one particular disorder and really don't systematically assess for other disorders. They have a bias in reference to the disorder that they are especially interested in treating and believe that most of their patients have."

This is why psychology and psychiatry are being abandoned. Read this from the sitting director of the NIMH:

http://www.nimh.nih.gov/about/director/2013/transforming-dia...

Quote: "While DSM has been described as a “Bible” for the field, it is, at best, a dictionary, creating a set of labels and defining each. The strength of each of the editions of DSM has been “reliability” – each edition has ensured that clinicians use the same terms in the same ways. The weakness is its lack of validity."

Well put, Doctor Insel.

This is like saying: "This is why biology and [insert-some-unreliable-medical-procedure] are being abandoned." (because said procedure was found unreliable). Without going into debate about DSM and psychiatric clinical practice, psychology has little to do with this. Terminology should be used properly, and we should be aware what words mean, especially if we criticize sloppy science or health care.

A wise choice, since that debate took place, psychology was found wanting, and is being abandoned as a result. Which part of this are you not clear about?

> ... psychology has little to do with this.

Psychology has everything to do with this. Psychology's basic premise is that there is a normal behavior, a "good thing", and we should all aspire to it. Meanwhile, in reality, evolution requires diversity to function. Diversity stands at odds with the idea that there is a single correct model for behavior.

The important thing to understand about evolution is that it's strongly backed by scientific evidence, unlike psychology's belief system. One piece of evidence in favor of evolution, by no means the only piece, is us -- we arose by way of natural selection, and this happened by way of innumerable failed experiments. No natural selection, no humans. That's strong evidence for how badly psychology pictures reality.

> Terminology should be used properly, and we should be aware what words mean, especially if we criticize sloppy science or health care.

Don't tell me, tell the director of the NIMH and the highest-ranking psychiatrist in the country, who is arguing for the abandonment of the DSM:

I cannot impress on you strongly enough that the present criticism of the field of psychology is entirely justified by facts.

[moocowduckquack]

"No, you are."

That stops being a valid debating tactic after around the age of six.

[SilasX]

Making assertions that you back up is always a valid debating tactic.

[moocowduckquack]

much as I appreciate fiction, I do expect it to have some kind of foundation to help with the suspension of disbelief
