Is Autism a Failure of Prediction?
This afternoon a group of MIT and Mass General researchers
released a study called “Autism as a disorder of prediction.”
In this paper, they argue that autistic people “experience things they don’t
understand,” because our predictive ability is impaired.
Interesting as this sounds, a close reading reveals the
premise as totally at odds with my lived experience. I think of myself as a friend to those
engaged in autism research, and I hate to come out in criticism of a newly
released piece of work, but in this case I feel their conclusion are just
wrong.
Anyone who has observed the prowess of a young Asperger video gamer would realize what a fool he'd be to bet against a kid like that's predictive ability. But that's not all. The hypothesis of this study does not hold up any better in my "real world" experience.
I do have some social disability, even now. My problem is that I cannot read the unspoken cues from
people around me. My ability to evaluate
what I do know – and to predict from it – is not weak at all. In fact, as a logical thinker it might even
be stronger than average. In other
words, I have a weakness in data input, when it comes to human-on-human
engagements. Too much of the wrong data
and not enough of the right data equals trouble, even with the best predictor
in the world.
No wonder we stim and compensate. They nailed that.
Otherwise, with all due respect, this paper seems to be a
perfect example of what happens with autistic behavior is interpreted by
neurotypicals, as opposed to having the behavior explained by those who live it. The study’s authors spend many pages
expounding on an explanation of behaviors such as I describe in my own books
and essays (Look Me in the Eye is one of their citations) when a conversation
with an intelligent, insightful autistic adult could have set the whole thing
straight.
Allow me to offer a comparison to put this in
perspective. Imagine that an alien
social scientist observes a human population and notes some puzzling and different
behaviors. Some of the people eat some
meat, but no pork. They call themselves
Jews. Some of the people don’t eat meat
at all, and they call themselves Vegetarians.
Some of the people don’t eat bread, and they call themselves Gluten
Intolerant. Some Gluten Intolerants eat
meat, and some don’t. Then there are the
ones who call themselves Catholics, and their strange seasonal aversion to
meats. They refer to the aversion as
Lent, and researchers scratch their heads to determine who’s the borrower and
exactly what was loaned, to render Catholics unable to eat like the others.
Why the different behaviors?
After careful observation, the researchers concluded that the Gluten
Intolerants had the answer. They admitted
to a biological deficiency; they cannot eat the foods others consume with
gusto. Researchers hypothesized that
Vegetarians and Jews were similarly affected but their food limitations were
subtler. They even suggested some meats may be toxic. After reading about empathy,
one researcher concluded the Catholics lent some un-discovered digestive
process to their fellow men for a period, so they too could be healthy. Their paper describing these discoveries was
published to wide acclaim on Alpha Centari, but the humans mocked its
conclusions when they read it back on Earth. The humans in the Alpha Centari zoo just snarled. The
researchers wondered why.
An old Gluten Intolerant offered them a piece of
wisdom. “Did you ever ask one of those
Jews or Vegetarians about eating meat?
I’ll bet they could give you the answer, and it isn’t what you think. It may be a mystery to you, but it’s no secret at all to them.”
The thing is, as aliens, they had absolutely no concept of religion. And the only thing they could conceive for Vegetarianism was the general concept of disability. The idea of a life choice was too strange to consider.
To an Autistic like me, this news is much the same. What it shows most of all is not insight, but the obliviousness of the researchers. I do not have a disorder of predictive
ability. I've met many other autistics and I can't think of a one with predictive disability. These researchers cited a line
from my book as support for their hypothesis, when in fact the whole book expanded on my
thoughts at considerable length, and made amply clear why I have trouble in
social settings, and it's not poor prediction capability. How about you?
Having said that, I concede that there may be differences in how I predict things as compared to how neurotypicals predict. But this study does not answer that possibility, nor does it present any new evidence for what a difference might be and how it might happen. The autistic narratives the researchers cite don't distinguish input problems from processing problems in most cases. In any case, their interpretation takes those writings quite far from the context in which they were intended.

As an autistic person I don’t perceive the same things as
neurotypicals. I make my decisions based
on different incoming data. It stands to
reason that my predictions will be different because the inputs to my predictor
are not the same.
What’s the takeaway here?
Bring the members of a community you want to study into your process at
the beginning. Be guided by their
knowledge, culture, and wisdom. Don’t let ignorance of another culture lead you
down a wrong path. It’s wasteful at
best, and can make you look like a fool.
As the neurodiversity activists say, nothing about us,
without us.

I am undiagnosed Aspergers and my son is diagnosed Aspergers, prefers autistic. He just decided yesterday MIT isn't in the mix for him - too much group work! Great irony.
Oh, and btw, to shamelessly promote my own book, geared towards kids to adults, those with and those caring for those with ASD, I also include a section of ASD from my unique perspective (giving an "insider's perspective)... Floppy Lop-Ears Tries to Get "Off the Spectrum."
Those are separately testable things that were confused by these researchers, I think
I hope Floppy Lop decides she likes where she is on the spectrum.
I don't think it's correct (or will be shown to be correct, given that this is a hypothesis) to posit that the social factor is "happenstance". To see what they were talking about, I watched the Heider-Simmel movie on YouTube. (Scary stuff!) Detail- and object-orientation--yes, absolutely makes sense that these would influence a greater percentage of spectrumites to not ascribe a social story than that of neurotypicals. Impaired predictive abilities? Irrelevant to this example.
On top of that, their account of Theory of Mind (which to me is a misguided relic of old-school black-box-psychology) as "inherently a prediction task" seems like a reach. Is seeing things from someone else's point of view a matter of being able to go from antecedent state to subsequent state?
There's more about this hypothesis that I disagree with (basically, how it's constructed--they've got an abstraction that they've fit to these selected attributes the way Erich von Daniken fit his story to his evidence), but I'd prefer to sit down and extract that from this paper before expounding.
But at this point, my gut leans towards Rochelle's comment, "Primary prediction issues or difficulty predicting due to getting false cues or failing to read cues...Isn't this just an issue of semantics?", and Florencia Ardon's, "But if researchers are going to use this paper as basis to look for the neurological mechanism, it is important to know exactly what part of the chain is not 'typical.'" I have a pet "hypothesis" that neurotypicals don't actually "have" a "Theory of Mind" that those with Asperger's "lack". Being empathic and able to accurately assess the past and making educated guesses about the future are things you learn from experience, and some are better than others. (Took me a while to even want to learn these, I'll admit!) And I'm all for helping people on the spectrum with these challenges.
It's easier to put yourself in the shoes of someone who's like you. If Theory of Mind was the norm, men would know how women think and vice versa, rich people would know how poor people think and vice versa, and cultures would know how other cultures think.
Any predictive impairment I have in social situations with NTs is because I'm different from a lot of NTs unless we have some common interest. Let me get to know you, and I'll get better at "predicting" you. And I had to teach myself to do the standard, generic, impersonal conversations that many NTs prefer to silence and to consider these conversations interpersonally meaningful rather than personally irritating.
Though I'll admit this... That the subway would be out of operation on a Saturday morning in Toronto--in hindsight, I should have been able to predict that. They probably wait until the work week is over to do maintenance. Gonna remember that one.
In general, if I were looking into what's different about those on the spectrum, I wouldn't look for what it is that those on the spectrum "lack" compared to the normative NT. That's kind of like studying gender communication dynamics as a matter of women "lacking" the skills to communicate as the "normal" males do.
Aspergers appears to be quiet hereditary (my dad, his brother, myself, probably my brother, my brothers 1st child... These people include only one without a degree (by age) and those degrees include a phd from caltec (Fienman gave the cargo cult science lecture at my dad's commencement) I have seen arrivals arguing that having a parent who is a college proffesor should be a rule out for Aspergers, funny, between John Robison, and Tim Page, all hopes I might have had a chance of publishing an autobiography about growing up in New England as the undiagmosed aspergian son of a proffesor. (Hell, Tim even mentions the same streets I have stories
To me that is a major failing. I stand by pointing that out.
Moving beyond that, I feel bad if you or the scientists felt I was scolding them because I am a believer in science and a believer in that school. I just took exception with how they did this and I think a flawed methodology led to flawed premises.
The researchers may well feel battered by the backlash of this story. For that I am sorry because that was never my intent.

Many NT's studying ASD seem to treat people on the spectrum more like specimens than human beings; and they say we lack empathy!
However I'm not as dismissive as you about predictive abilities in ASD. In fact my first post in my Aspie Brain blog was about brain prediction circuits.
I think an important distinction needs to be made between intuitive and cognitive abilities. For example you might cognitively understand gravity and wind resistance, but if you can't intuitively predict the motion of a baseball, you're not going to make a hit.
Where I do agree with you is that the problem can be with the data or the program. For example if social problems are due to a lack of instinctive knowledge rather than intuitive predictive ability, then reasonably accurate understanding and prediction of social behavior can be learned.
