Not necessarily. Behaviour is ostensible, not merely self-reported.
Sure, but that's not how psychology is practiced.
Psychology is practiced on the self-reporting of behaviour, not on the observation of behaviour.

That which is "rational" conforms both to logic and to the way things are in the world.
So I called it. A correspondence theory married to realism.
Why should anyone care about the way things ARE in the world, if they WILL be different tomorrow?
A rational person does their best to ensure things WILL be the way they want them to be. Utility maximisation.
Logic has nothing to do with reality. Logic not even that popular amongst Eastern philosophers.

Then you'll have to explain why things like Lithium can address it.
Because it's caused by Lithium deficiency?!?
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
Because Lithium, and whatever similar chemicals will produce the same effect, are from the environment.
The environment may or may not have caused the Lithium deficiency in your brain. Any number of things could've caused it. Diet. Genetics. Some other disease.
Do observe, however that nobody cares about "what causes it?", if Lithium fixes it.
Utility maximisation.

I addressed this: the category error is
yours, not mine.
And I addressed that too. The assertion of an error is yours, not mine.

I did not introduce the hemophilia example...nor, for that matter, did I introduce psychopathy as a case. They were both yours. And I made no analogy between them -- I'm arguing (rightly) that any such analogy is bad.
You did that.
So you really are that stupid.
Are you actually aware that "sameness" and "difference" is the foundation of recognition? And the very process by which categorization works.
That you don't agree with my "categorization-sheme" it doesn't mean that it's wrong. If my categorization scheme maximises my utility - then I don't give a shit if you think it's "wrong".
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
I can say that about every living being. But in point of fact, hemophiliacs do not all die.
*sigh* Fucking sophist.
With proper treatment, life expectancy of a haemophiliac is about 10 years less than healthy men.
This is where you go "15% shorter life expectancy is nothing to cry home about. It can be safely discarded to conclude sameness".
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
Unless we accept your assumption that there's no such thing as intrinsic psychopathy, then we are not deducing from psychopathic behaviour to psychopathy. Rather, we can do things like dispositional testing, with "blind" subjects, to locate psychopathic dispositions.
And THEN (once you have classified people as "psychopaths" you actually have to demonstrate that the classification actually correlates with some 3rd variable. And you have to demonstrate that the correlation-rate predicts DIFFERENT OUTCOMES than the general population.
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
From that, we can asses a higher statistical probability of psychopathological doings in populations.
You are correlating it back to the very DOING which define psychopathy. It's circular - you aren't acquiring new knowledge from a psychopathy diagnosis. You are affirming the definition.
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
It cannot prove
who goes to jail; it can show that
a percentage of them will.
A percentage of non-psychopaths will go to jail also. A vast majority of psychopaths AND non-psychopaths don't actually end up in jail.
Selection bias.....
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
But all of this is moot. Where are we going with this?
I have no idea. That's why I asked you what your utility in categorizing people as "psychopaths" is?
That's why I told you that the method of diagnosing "psychopathy" matters to me.
Self-reporting - don't care.
Material evidence and body count - I care.
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
It depends what you're trying to "predict."
I am trying to predict my likelihood of having to deal with violence.
Self-reported arm-chair diagnosed psychopaths - lower risk.
Ex-convicts/repeat offenders - higher risk.
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
The diagnosis of psychopathy is "broken" only to the extent that it can't tell you what a given
individual would do; it's quite excellent for telling you that statistically, aggressive and antisocial
groups, such as convicts, are going to be disproportionately psychopathic.
Exactly! So I don't care whether you are a diagnosed psychopath. I care if you have been convicted of a violent crime.
The latter carries more information.
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
It's the "mixing" part I'm suggesting is fallacious.
You are the one harping on about "logic" but you haven't even heard of
intersections?!?
Perhaps your logic is broken. Have you tried a different one?
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
You can pick the category you like: but mixing categories, like going from physiological to psychological, as you have done, is going to produce fallacious conclusions.
Is that what they told you in Philosophy-school? Shame
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
Is your claim that physiology and psychology are the same category? Bleeding is like thinking, you imagine?
In some ways they are the same.
In some ways they are different.
If the sameness is important to the predictive model they are "the same".
If the difference is significant to the predictive model then they are "different".
This is how abstract thinking works, you know?
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
Heh. Your understanding of Eastern philosophy needs some work. They always think in categories...just different ones from the West.
Q.E.D By tweaking the knobs on "sameness" and "difference" you can arrive at any conclusion you want. I know this. I do this.
Maybe you are ignorant of the fact that you do it too?
I am way too tired to refer you to all the experiments. Here's a book instead:
The Geography of Thought.
You will find about 15 pages of references on the back.
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
Well, irrationally, then, you kept only one criterion, and arbitrarily rejected the rest?
By your conception of "rationality" which has nothing to do with my own.
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
No. Given the absurdity of your claim.
My claim is not absurd if you take the Medical view on the matter.
But since you've settled for "absurdity", it's safe to conclude that you are a layman.
Immanuel Can wrote: ↑Sat Jan 11, 2020 11:33 pm
No, you don't. But you do have to have some point. Right now, I'm not seeing any.
My point is that there is no point. Until we calibrate our respective utility-functions.

Ah, so you think the reasons the jails are full is because of diagnoses of psychopaths?
That's quite the stretch of a strawman
No shit. That's why you are on this forum.
