There's a relatively new movement in the communities of people who deal regularly with autism and related conditions that's assigned themselves the term "neurodiversity" as a shorthand reference to their commitment to affirming atypical neurological conditions as equally legitimate. This movement shuns the terms 'normal' and 'abnormal' and instead prefers to speak of those who are neurotypical and those who are not. The neurodiversity movement seeks to identify various traits common with autism as neither better nor worse but simply different.
This movement should be praised for its recognition that respecting people with autism requires taking into account how differently they take in information, process it, use it, and produce various responses. They rightly emphasize that an atypical neurological state need not be thought of as a disease that needs a medical cure or treatment or a disability that requires taking the person to be deficient. They recommend supporting a person for who they are rather than trying to "fix" them to conform to the standards everyone else has. Some autism advocates on the autistic spectrum insist that they wouldn't want to be made "normal" if a "cure" were ever found. They like being the way they are. There's something obviously right about most of that. The more I read stuff from this movement, however, the more disturbed I get that there's something they're just not seeing, and the good in what I just wrote is blinding a lot of well-meaning people to a serious philosophical error lying behind much of what the neurodiversity movement produces. Consider this story [link dead and removed] by Karen Kaplan of the Los Angeles Times. She is right to point out that, just because autistic people do badly on certain standardized tests, it doesn't mean they're cognitively deficient. It may well be that the reason a certain person scores low on a certain test is because the test is relying on typical patterns of language use, and someone with autism may be using a different pattern of language use. The underlying cognitive ability being tested for may be stronger than the test shows. That's all correct. But in her rush to make this point, Kaplan completely ignores the fact that the reason someone is scoring low on the test is because of a genuine deficiency in the kind of language use that most people are much better able to engage in. That means there is a lack of ability that comes with autism, even if its manifestation will be different from person to person. Again, Kaplan speaks of those who emphasize "training kids with autism to behave like typical kids instead of allowing them to make the most of their differently wired brains." That's especially helpful, because allowing autistic people to make the most of their differently-operating brain is certainly the right goal. But that's perfectly compatible with taking their differently-wired brain to be operating at a deficient level with respect to certain cognitive skills, even if it's also operating at a higher level with regard to other cognitive skills. Some in the neurodiversity movement are willing to recognize that differences between neurotypicals and autistic people involve autism conveying certain strengths and weaknesses. But the language of "not better or worse but just different" disallows any such recognition and smacks of crude relativism, whereby we cannot recognize any difference as being better or worse. When taken to its logical implication, we'd have to say that someone who is not intelligent enough to read is not less smart in any respect than the norm, just different. I submit that such a statement is nonsense. There's a particular cognitive ability that allows for reading that most people have, and someone who doesn't have that ability (assuming they genuinely don't) is lacking a cognitive skill. Why can't we just accept that? Similarly, there is a seeming refusal to recognize any medical condition that can be spoken of in terms of being made worse off. In some respects this strikes me as a general problem among disability communities that stems from crudely relativistic thinking. The deaf community is largely unsupportive of cochlear implants, because it gives children the ability to hear, and they take their lack of hearing not to be a genuine disability. There's nothing wrong with not hearing, so why should they support giving deaf children the ability to hear the way most people can? If we really took this line of reasoning seriously, we'd have to apply it to other conditions that virtually no one wants to see as perfectly normal. For example, one could argue that pedophilia is just a different way of being, and we should respect it. After all, it's caused by a brain condition, and all brain conditions are equally good. In terms of the arguments I see from the neurodiversity movement, I see no way to say the things they say while avoiding such a conclusion. There are plenty of ways to distinguish between the two cases, but I don't see how those are available given the extreme sorts of statements that I regularly see among neurodiversity advocates. People who have serious cognitive deficiencies often have serious problems seeing their own intrinsic worth. It's important to affirm that. It's important to help them see that their very existence is not wrong in the sense that we should blame them for being the way they are. It's important to help them see that their preferences may seem weird to others but that in many cases perfectly all right for them to have them. But some voices advocating for neurodiversity want us to say that someone with autism is not messed up in any sense. The fact is that we're all messed up. We're all distorted. We're all flawed. No one is the way we ought to be. Autism is one way to have various deficiencies, one that also happens in many cases to have plenty of strengths above the level typical of most people. To say that we can never evaluate being less good at something or more good at something with such value-laden language would be to overreact to a genuine problem in how many people look at people with disabilities. But on one level, I can't blame the neurodiversity movement (and the more general relativistic outlook among other disability communities). After all, their view follows fairly easily from a particular version of secularized naturalistic thinking. Different neurological conditions stem from natural variation, and there's no other level of explanation but natural variation. There's no God who designed human beings to have certain capabilities. There are no natural purposes according to which organisms have a nature, and certain capacities are part of what a well-functioning member of their species will be able to do. There's no notion of well-functioning if your worldview doesn't allow for higher-level explanations about purposes and design, other than perhaps simply asking whether a particular organism fits into the way most members of its species are or whether it fits the patterns members of its species typically desire for themselves. There's nothing objective about what a healthy member of that species or a well-functioning member of that species would be like. There is no way we can have a notion of the way we ought to be if there's no ground for what it would be to be the way we ought to be. But such a conclusion seems to me to be so obviously false that perhaps we should just question the metaphysical underpinning of the neurodiversity movement, rather than giving in to that metaphysical picture's logical implications.

Alan Turing famously devised the Turing test, which was intended to test whether a machine can think. If it could show enough behavior consistent with thinking, Turing claimed that it really does think.
Turing tests have come under quite a lot of criticism for relying on the fallacious inference from something appearing to have a certain property to the conclusion that it does have that property. Turing tests take the behavior that follows from genuine thinking to be sufficient to establish that there is such thinking, even if the same behavior can be produced by a computer program. I would take the fact that it comes from a computer program to be sufficient reason to think such behavior can occur without genuine thinking. So the usual criticism of Turing tests is that they assume thinking is occurring just because the usual behavior resulting from thinking is occurring. While I'm not interested in diminishing that objection, it occurred to be recently that Turing tests aren't just not sufficient for thinking (things that pass the test might not be thinking). They're not even necessary (things that think might fail the test). For one thing, someone who thinks might simply refuse to comply with the test and thus could fail. But more poignantly, someone with a communication-related disorder, e.g. someone with autism and dyspraxia who is completely non-verbal, simply cannot display the behavior the test is looking for. Being unable to communicate is certainly not a sign of being unable to think. I would argue that more harm is caused by those who take passing a Turing test to be necessary for intelligent thought than is caused by those who take passing such a test to be sufficient for intelligence. We recently attended a communication seminar for parents and educators of non-verbal and mostly non-verbal children. At one session an autistic college senior was present. He can now speak in a somewhat limited manner, but he can communicate by typing on a portable device at a level that's almost certainly far beyond what most kindergarten teachers would have ever expected if they had seen his communication level in his younger years. He had no verbal language until age 12, but because his teachers taught him to type they knew that he was able to grasp much higher levels of thought than most teachers would have even speculated. At last night's session, there was a guy with Down Syndrome and autism who, as far as I could tell, can even as an adult do little more than grunt was typing out sentences that indicate a pretty high-level grasp of some pretty abstract and complex phenomena. With a son who can't speak much more than five syllables at a time (unless he's singing or engaging in echolalic repetition of Veggie Tales or some other TV show), we've been able to see something like this firsthand. We knew in kindergarten that he was reading fairly complex words for the level of verbal behavior we normally saw, because he'd occasionally see a word and say it. (I remember him saying "banana" one time when there were no pictures of a banana, just the word.) But it's been very hard to get him to demonstrate his intelligence with writing, until this year, with his teacher and support staff working very hard with him to get him typing. Six months ago we could get him to trace over words we wrote out with a highlighter, or we could get him to point to words sometimes on a communication device, which could then pronounce them for him (but they had to be programmed in first, since he wasn't typing them). Now he's showing reading comprehension by completing "because" clauses to answer why certain characters did certain things. It makes me wonder how much he's been wanting to be able to communicate for years but unable to get his mouth or hands to do anything to show it. The Turing defender might now say that he is able to show it, so it's not an objection to the test, but he's only now able to show it, and there's no reason to think he just started to be able to think on this level. I suspect most teachers would have assumed he couldn't handle the level of math that he's doing (basically right on second grade level) or the vocabulary and reading that he's doing (which is, as I said, at a pretty good level for demonstrating reading comprehension, better than his older brother could demonstrate at that age). He happens to have a teacher with 25 years of experience working with kids like him, who is informed about technology and methods to get kids like him communicating. Many educators encountering a kid like him might well assume low ability levels and not work to get him to communicate. In effect, they're using a reverse Turing test and concluding that someone isn't intelligent because they can't show it in the typical ways. |
