Do you prefer the term uncommon? I could substitute 'abnormal' for 'uncommon' in every post up till now and the content would not be changed. 'abnormal' means 'uncommon'. Uncommon is not subjective, although there are degrees of commonality.
If someone has a physical property that less than 1% of the population has, do you think anyone would seriously object to it being considered uncommon or abnormal?
“Elections are Futures Markets in Stolen Property.” - H. L. Mencken
"do you think anyone would seriously object"
I guess it depends on the context. Olympic track runners are uncommonly fast.
the point is, why are you telling the guy with palsy who never leaves his house that he is "uncommonly spastic?" its like when people (who happen to be evolutionist/atheist) will remark upon observing an individual who (they believe) has an extra chromosome. You walked right past the 6'4" dude with red hair and green eyes, but this one deserves mention! Are you an anthropoplogist? A tourist?
we arent so far removed from a society that decides that certain humans arent fit for life. This is ungrammatical as well. Humans that are alive do not need to have their existence approved by anyone. If you believe in an ideal standard of humanity, then you are religious.
This entire time I have been entirely descriptive. As a moral fictionalist I am not making an argument that there is anything wrong with being uncommon or that 'brain abnormalities' are wrong. I am not even making the argument that behavioral disorders (by which I mean behaviors that are produced by specific abnormalities in the brain) are 'wrong' and need to be fixed. That is up to each individuals personal evaluations.
But to argue that, in circumstances where people don't mind the symptoms, the abnormality disappears is frankly wrong.
"I'm not sure how useful it is to refer to refer to "commonality" of body parts"
It turns out to be very useful in cognitive science and psychology because abnormal/uncommon brains tend to produce abnormal/uncommon behavior, the study of which helps us both understand how these brains work as well as how our own 'normally functioning' brains work.
also, human behavior isnt a subject that one can evaluate from a medical perspective. Its simply not within their domain to conjure into symptoms. Like pms.
when you refer to "uncommon behavior" do you mean like hoarding junk or like going to school for 20-30 years so you can cut open brains? You cannot seriously tell me youre using abnormal or uncommon to refer solely to statistical likelihood of occurrence. Is snowboarding the result of an abnormal brain?
Of course I don't mean stuff like that. I am talking on a lower level of abstraction, things that effect emotional reactions and decision making, as well as perception. These things influence and color a persons behavior. Someone with a damaged left-frontal lobe, for example, will make a variety of different decisions. Not "I used to snowboard but now I don't". However, they can affect more fundamental things such as addiction, risk avoidance, sexual appetite etc.
There is a great body of research on the brain and how specific areas interact in order to produce types of perception as well as behavior.
"You cannot seriously tell me youre using abnormal or uncommon to refer solely to statistical likelihood of occurrence."
Of course I am. Synaesthesia is a statistically unlikely symptom of statistically unlikely brains. It is also one that has some potentially beneficial effects. You once again can't get over the fact that abnormal is not necessarily a value-laden term. Life is abnormal. Intelligence is abnormal. You are the product of a long history of accidents. When you look at the big picture, you are EXCEEDINGLY abnormal.
The whole point of studying abnormal brains is so that
1. You can treat it if desired
2. You can further understand how brains work
In the same way that you can learn how a system works by removing one part and observing what happens, you can learn how a 'normal' brain works by studying the tendencies of brains that are similar in all but a few ways. That is why it is a useful discussion, morality has nothing to do with it.

"Yes, people with head injuries act differently than they would without the head injury, even unto avoiding the risk of further cranial trauma. How is that different from ceasing to engage in snowboarding? "
Some people with brain damage change their entire personality. Some become uncontrollable emotionaly, some become violent, etc. It's not the same as changing one's activities, its changing one's temperament.
"Anyway, with an injury there is an ideal uninjured head you can refer to. Thats something we can agree on. But earlier it seemed like we were discussing common or uncommon brains. Now its baout brain damage?"
Sometimes genetic variation produces brains that are similar to ones with brain damage. But, that is besides the point. Damaged brains are uncommon brains as well.
"no where in any of this research did they manage to identify an objectively correct brain, so that you could refer to other brains in relation to that one."
Objectively 'correct' is a misnomer. You are trying to lead the conversation back to where you have a point. 'Correct' has nothing to do with biology.
The kind of brains that they study ARE uncommon. They are rare, and differ from 'average' brains (can be determined using random sampling) in measurable ways.
I think you are trying to hard to justify your objection to the language.

Neurologist and neurosurgeon are careers. Synaesthesia is a perceptual disorder. One is studied by cognitive scientists, the other isn't.
The point isn't to just study uncommon behavior, as that can be the product of many different things, most being irrelevant to the neurologist's trade. The point is to study 'rare' brains (1 in 2000 counts as rare, I suspect, to everyone who isn't being intentionally thick) and search for systematic, statistically significant patterns of behavior.
If you parse 'abnormal' as anything but 'statistically uncommon, rare, not average' one more time, this conversation is over. I'm not going to beat my head against a wall in attempting to persuade someone who is intentionally misinterpreting everything I say.
My point is simple. Certain statistically uncommon brains percieve/react/value differently than brains that do not share their physiology. These perception/reaction/valuation differences are not random but caused by their physiology. This leads to observable, measurable differences in behavior and personality.
Assuming that Szasz was not referring to 'abnormal' in a normative sense in his quote that 'abnormal behavior is not a product of abnormal brains', he is wrong.

How specific are you going to want me to be?
If I said
"Subjects with a uncommonly functioning fusiform gyrus, whether by genetics or injury, when compared with the average functioning temporal lobe (approximated from years of random sampling data across all populations), exhibit exceedingly uncommon perceptual symptoms and behavior.
would you want more detail?
You might want to read some actual academic papers then.
BTW, brains produce 'agents' (or the illusion of them) which produce behavior. So...
edit: behavior does not mean activities. For example, people with injuries to specific parts of the frontal lobe become hopelessly addicted gamblers. Does this mean the frontal lobe determines if you are a gambler or not? Not directly, the actual behavioral change is that of thrill seeking and risk avoidance, namely more of the former and less of the latter. This behavioral change can be expressed in many different ways, and gambling addiction is just one of them. If they lived in the Alps with no casinos around, those same individuals would probably be doing this.
That's why I said that these things affect temperament.
""You might want to read some actual academic papers then.""
so you cant explain why relatively frequent patient-reported sensory percepts aka "synaesthesia" is the product of an abnormal brain but (by comparison much more uncommon) 3 decades of compulsive behavior that results in legal authorization to saw crania and pronounce on "normal and abnormal brains" is not? Color me surprised!
I think brains 'create' consciousness and agency, or the illusion thereof. As do the majority of cognitive scientists/biologists.
I could explain the physiology of synaesthesia, prosopagnosia, and many other symptoms of 'uncommon' brains. The work has already been done for me, however.
so its even easier to plausibly connect potentially unrelated things! Thanks scientific method, for takng a break!

Don't pretend you know anything about the scientific standards these studies hold themselves to, it's not like you've read any of them.
Oh wait, I forgot that this community is now infested with conspiracy theorists and science-skeptics.
They are uncommon because their prevalance in their relevant population is like 3 standard deviations from the mean!
edit: I need to start compiling my disbelief to one post, in case it looks like I'm spamming.
The brain processes information, as well as determining physical actions. I'm not sure if you are trying to be clever or if you actually think there is anything else 'in control'. I think you know what I mean.
zefreak: They are uncommon because their prevalance in their relevant population is like 3 standard deviations from the mean!
"Thats a truism. If you cant answer the question, which conclusion seems inescapable at this point, just bow out gracefully."
Hah. You asked how I knew that brains that exhibit syaesthesia were uncommon. You accept as a truism that a sample 3 standard deviations from the mean is uncommon. 1 in 60 people have colored grapheme synaesthesia. That is beyond your accepted threshold for being classified 'uncommon'. The physiological peculiarity that causes colored grapheme synaesthesia is known. Therefor that physiological peculiarity is 'uncommon'. The brain that has that physiological peculiarity is 'uncommon'.
"so its even easier to plausibly connect potentially unrelated things! Thanks scientific method, for takng a break!"
Right, you are not implying anything about the scientific standards held by cognitive scientists. Just asking questions.
"are you implying that it would be somehow preferable to have faith in (whatever it is one happens to call) "science"? Skepticism is a bad thing, since when?"
Motivated skepticism is a bad thing. For example, someone who has done 0 research into cognitive science who is 'skeptical' of the scientific veracity of its findings is not being a skeptic, they are being lazy. Just an example.

As for the rest of your questions, if you were educated enough in the field to have a general understanding of the basic findings/reasoning behind their conclusions, we could debate specific points. At this point, the amount of information I would have to spoon feed you is honestly too much for me to bother.
Maybe it's your method of arguement that is the problem. I would much rather you state your objections clearly than bullshit around asking me leading questions as if I had all day to reach your point for you. I recommend doing a little reading about cognitive science, it's general findings and the methodology they use. It's not one study that the conclusions regarding the relationship between brain and personality/behavior come from. It's thousand of individual findings that coherently support one another, each additional finding adding confidence to the hypothesis.
As for how I conclude that the brain 'determines' physical actions, the heuristic used is called 'Occam's razor' and its modern mathematical form is Solomonoff Induction. Of course, you would have to do plenty of research on the subject in order to build up the evidential basis to the point where you are persuaded, and I don't expect that to happen. If you have any specific objections however, or any data points that you think cannot be explained by materialistic determinism, please bring them to my attention.
