Conversations with Tyler - Michelle Dawson on Autism and Atypicality

Episode Date: August 1, 2018

Perhaps no one else in the world more appreciates the challenges facing a better understanding of autism than Michelle Dawson. An autistic herself, she began researching her condition after experiencing discrimination at her job. "Because I had to address these legal issues and questions," she tells Tyler, "I did actually look at the autism literature, and suddenly I had information I could really work with. Suddenly there it was, this information that I was supposed to be too stupid to work with." And so she continued reading papers - lots and lots of papers - and is now an influential researcher in her own right. For Michelle, the best way to understand autism is to think of it as atypical information processing. Autistic brains function differently, and these highly varied divergences lead to biases and misunderstanding among typical thinkers, including autism researchers. In her conversation with Tyler, she outlines the current thinking on autism, including her ideas about cognitive versatility and optionality, hyperlexia and other autistic strengths, why different tests yield wildly different measures of IQ among autistics, her 'massive bias' against segregating autistics, how autistic memory is different, why sometimes a triangle is just a freaking triangle, and more.

Michelle is one of the people I admire most, actually. she has become a very well-known and very influential autism researcher.

Her background, she is herself autistic. In some regards, you could describe her as self-taught, but she has become a kind of one-woman force advocating for more science. And you're shaking your head now. I'm not an advocate. She is arguing for science and ethics being brought into the autism discourse and discourse more generally. Would you accept that description of what you do?

Good enough. Good enough. Fair enough. Let me start with a very general question. If you ask, what would be the most underrated, non-accountable and mysterious force controlling people's lives? And I said that right now it was actually something called the DSM, diagnostic and statistical manual of mental disorders,

which influences a lot of issues in the law, what insurance companies do, what hospitals do when people are institutionalized? What would your reaction be to that statement? I think that the DSM could be a very bad, big deal to people who, for instance, are denied basic human rights or standards in science. For people who are not situated like that, and that would be most people, the shortcomings of the DSM-5 will be offset by people in research and practice who have given.

standards who understand that their job is to benefit people more than they harm them, who know how to read the scientific literature and so on. So it depends who you are and how you situated. And also you have to consider the larger context of what people see as influential or not, which might be very arbitrary at any moment. So what would be the best understanding of autism from your perspective? The best understanding is seeing autism as atypical brain functioning resulting in atypical processing of all information. So that's information across domain, social, non-social, across modalities, visual, auditory,

whatever it's source, so whether it's information from your memory, information coming from the outside world, that that is atypical. Now, so that is very domain general atypicality. what autistic brains do with information is atypical. How it's atypical, in my view, involves what I've called cognitive versatility and less mandatory hierarchies and how the brain works, such that, for example, an autistic brain will consider more possibilities, will non-strategically combine information across levels and scales without losing large parts of it, and so on, and that applies to all information.

So that is strictly my view. I'm not sure anyone would agree with me. Do you think it's true that autistic brains somehow take in or process more information? They can. So that depends on what is available in the environment. And not all autistics are well situated when it comes to access to information that they can process well. So autistics are different in the kinds, quantities and arrangements of information they process well. So just having a huge quantity of information is not necessarily.

all that an autistic person needs. The atypicality is more complex than that, but yes, an autistic person can process more information across levels and scales without losing it or without, you know, a lot of the information sort of being edited in sort of cognitive editing, various ways that information is made manageable in a typical brain. Autistic people don't need to do that to get the information.

in a way that it can be processed and useful that they can learn from it and use it. So what's an example of something an autistic person might be better at doing than a non-autistic person? Again, with a lot of variation across autistics. You know, the problem here is that there's a really long list of things that autistic people can do well, given the opportunity. Give us, say, half a dozen, just bullet points. So, I mean, the sort of almost classic example is, hyperlexia, which you see in starting with very early development. So you see this in very young autistic children

who have a spontaneous interest in printed materials. It can be just text, but the information can include other kinds of printed materials and numbers, combinations of letters and numbers. And they use this information across different, scales. So from individual letters like the alphabet, given the opportunity, they will

order individual letters into the order of the alphabet, for instance. But they don't just use single letters. They will also use complex arrays of text like newspapers. So these are very young children. This can, you know, start at age two.

If they're in a book-rich, text-rich environment and have free access to this, they will figure out how language is structured. And that happens even with very difficult orthographies like English. So English orthography is so difficult that typical children take an extra year or so to learn it because it's wacky. I mean, it's not, in a lot of ways it doesn't make sense. The rules don't make sense. But autistic children, even starting, you know, these very young children can work this out. You know,

they figure out the irregularities. They figure out the regularities. They figure out the regularities with using this sort of array of information from words to, you know, letters to words, to phrases, to sentences, to paragraphs, to entire text and arrays, and so on, and they will figure it out. And typical children don't really do this spontaneously. My mother used to tell me that when I was two, I just taught myself how to read, and for a very long time I never took her seriously. I just thought, well, mothers say things like this. But when I learned about hyperlexia, it occurred to me that she had an actual literal

point. So if you're a hyperlexic and then you grow up, you keep some kind of special reading ability typically? We don't know nearly enough about how any autistic strength in processing information evolves over time. And again, you have to keep in mind that we start looking at this when, you know, in children, you don't know what kind of information is going to be available to them. We are not paying attention to that at all. And, At the same time, now in autism, one of the most common aspects of popular interventions is to really ration information, keep it away from autistic people. So you have to consider that in how an ability develops. Do they have, what kind of access to information do they have in whatever context they're in, whether it's in their home, in their school?

But it is not a dead end. That is for sure. It's been thought of wrongly as a dead end, and that's been true of, you know, autistic abilities in general that they are thought of as dead ends. But it's clearly not the case, even in situations which are very far from good for the autistic person as far as availability of information. And their overall situation with respect to how resourceful they can be, how they can add to and build on their abilities and so on. Now, often in popular discourse, you'll hear autism or Asperger is associated with a series of personality traits or features of personality psychology. So a kind of introversion or people being nerdy in some regard. In your approach, do you see any connection between personality traits and autism at all?

There is a small literature that shows some connection. I think it's very weak, and I say no. I don't think autism is about personality. Autism is sort of orthogonal to personality. it's not, the two are not related. You know, whatever relation there is does not, you know, arises from some third factor, let's say, if there is one. And, you know, again, the evidence is, I think,

very weak connecting autism to personality. So just say that maybe if there's something, let's say that personality in autistics might be more high variance. That would be my totally wild guess. but I don't think autism itself is about personality. One thing, if I think about your work in general, one thing it's caused me to do is to see a new bias in how humans make judgment,

and that is a bias to underrate atypical kinds of intelligence. And I view this as a common thread running through your work, and maybe this is what I'm reading in, rather than anything you've said explicitly. But if you look at, say, issues of animal intelligence, There's a growing body of evidence that animals feel pain. They're intelligent. They lead social lives. They're complex in ways. Maybe we hadn't understood earlier. Still, a lot of people don't absorb this knowledge very readily. If you consider Down syndrome individuals, when I was growing up, there was a common sense of a kind of hopelessness. Now there's a Down syndrome individual who's a lobbyist, people playing roles on TV and so on. And this would not have been expected by most people in the 1970s. So why do you think it is we have this bias to underrate a typical kinds of intelligence, or do you even agree with that characterization?

I would be careful about the sort of people in general. I would say that maybe there does seem to be something that, if you take sort of the median person, that, you know, or you do this sort of as a, you know, as societies sort of collectively, not necessarily as individuals. It seems to be something that people are very bad at, is to detect abilities and worth in highly atypical individuals.

And you, for sure, I mean, you see this very much in autism with the whole notion of severity, and there is no workable definition of autism severity. People use that word all the time. They use it to mean that, somebody's had a bad outcome, or that someone is badly behaved, or that somebody performs badly on an IQ test, and so on. Just something, there's something bad going on here, and it's sort of

the equation that the more atypical a person is, the worse they must be. They must not be intelligent. There must be something extra wrong, more wrong about their behavior, and so on. Now, this is where I'm very familiar with the whole history of this, and it's obviously problematic. I mean, we don't, I hope we don't. Look at a blind person who is a successful lawyer and assume that he's only very mildly blind or not, you know, barely blind at all. And then look at a blind person who has a very bad outcome and assume that they must be very severely blind. We do make those kinds of judgments in autism as saying the more atypical the person is, the worse they must be in some sense. Now, that kind of bias has not only harmed a lot of autistic people, it really has impeded research.

And we do not have a definition for autism severity. But it gets that idea, that bias, very unhelpful and harmful bias, that the more atypical an individual is, the more there must be wrong with them. I mean, in autism, it's been pertinent. It's just, you know, if you want to take autism, it's almost the paradigmatic case, of that happening. So if you want to make a case for that, autism would be where to do it. Are there biases that non-autistic individuals have that autistics might have less or maybe not at all? Well, there's a literature testing some of these biases. You know, the short answer is yes, though. I think in all cases you would want to, you want a bigger literature, you'd want to wait for replications and so on. What's an example of a possible bias that's weaker in autistics?

Well, noticing that two offers, which are posed in different ways, are actually identical, are being more likely to notice that the outcome will be identical, however it's supposed. So those are framing effects. Now, that's been replicated once, where in effect, the autistics are less likely to be fooled by the framing. So they, they determine. detect when two situations are the same, whereas the typical group are biased such that they are fooled by the framing. You know, and it's not 100%, but autistics are just, they will still consider it. What about optical illusions? Is there evidence there? It's very mixed, and it's very picky about the task and the instructions. So some more than others, I think that the table,

and now I'm trying to remember the shepherd's table, or have I got the name of the table right. The table illusion has been replicated. The one with the line, now I've forgotten its name, has been replicated. Others, not so much, and you do, it's very mixed. I don't think there's a question of what can autistics see an illusion. They probably can. Do they consider other possibilities? Yes, they do, and they will consider other possibilities that the typical population might not. So that produces some, you know, some differences in results depending on the task and so on. Are there examples of confirmed biases on autistics where the bias is stronger in autistics? I would say no. Keep in mind what I think here is not that autistics don't have biases.

Autistics can, they will process information atypically within that range is the possibility of checking, you know, What is the etypical hierarchy, even if it's not? It won't be mandatory, though. That won't be it. They will consider other possibilities. So that will attenuate biases as opposed to strengthen them. And that, I think, is what you find in the literature. You know, again, depending whether the task is sufficiently complex for that show up,

what the task demands are. You know, my favorite of these is that, though it doesn't, It's a bit dodgy because it comes from a couple of different papers, but it shows where a bit of my background going way back in perception and finding that autistic people were better at drawing impossible figures. So impossible figures are like penrose triangles. They're things that you can't build. And so this was interpreted as a couple of possible deficits.

You know, they're not failing to see the global structure, for instance. Yet, if you ask autistic people, whether the impossible, figure is impossible, they know it's impossible. So autistics can have both the possibilities. They understand that an impossible figure is a sort of possible drawing. Now there are a variety of claims that autistics either have difficulties processing social information or lack certain kinds of social intelligence, whether awkward in particular social situations. In your framework, how do you make sense of these claims and how would you describe or redescribe the phenomena people are talking about?

How autistic people perform in social tasks is high variance. It is very hard to pull out specific deficits where you can't point out areas where autistics have performed, at least as well as typical people on the task. Now, there is an exception, which is the most replicated autistic deficit. I believe there's one finding in the contrary direction, but all the rest of the rest of the rest, and there's a lot, especially for the autism literature, show what is considered an autistic deficit. So this is the task of attributing deep mental states to geometric shapes. Usually there are triangles. They will be animated. They sort of move around. And it goes beyond simply attributing

agency to the triangles, which autistics can do. You must attribute mental states to them, profound mental states, like they're jealous or they're flirting. And Autistics are very bad at this task. And this has been replicated quite a lot, even at a population base level, which is not something you necessarily see a lot of. So is this a social deficit? Autistics are definitely bad at this task. Now, why might that be if you look at things in my own biased way. It may not necessarily be that autistics don't notice that these interactions between geometric shapes

or among geometric shapes resemble something social that involves mental states. But there are less likely, and they are not going to totally get rid of the accurate information, that these are just freaking triangles. They will only go so far. You know, they are not going to lose that possibly important information,

that these are just triangles, and this might, you know, that you would think that this would be quite reasonably produced a bit of caution in assuming that you know quite a lot about their profound mental states. It's the following a fair description. Let's say that many autistics are taking in more information than would be typical. So sometimes those autistics will end up confused or they will feel confused or act as if they appear they're confused. But other times if they develop procedures for processing that information rules, they become better at interpreting the information. Maybe they have to become better because they face this more difficult task.

So you will have autistics show unusual mastery of social situations. Even if they appear awkward, they'll see much more detail than non-autistics would in some cases. but then in other cases they'll be more confused, and that's where this high variance comes from that you mentioned earlier. There's a huge literature and autism about how autistics judge facial expressions of emotion in other people. What you have in the autism literature is you haven't only just turned autistic people into sort of stereotypes and cartoons. You've done that to the typical population.

This is really at odds with the non-autism literature, on facial expressions, which is much more complicated. In the autism literature, it's assumed that you can just read people's inner emotions and mental states, which are not necessarily well defined, that it's sort of a simple matter, that it is sort of written all over somebody's face, or even you can read it just from looking at a photo of their eyes. And things are far more complicated than that. the literature in the non-autism literature. And for example, the MIT, their affective pitting group, Rosalind Picard did these fantastic studies showing that people smile and frustration

and those are real honest to goodness, Ekman type smiles. You know, you have the whole facial action coding thing going on. Those are real genuine smiles that people smile and frustration when they're genuinely frustrated. They don't do it when they're acting out frustration. And there are many other examples like that. People smile for many different reasons. It may, they may, and that is acknowledged to some degree in the literature in the typical population, not in the autism literature where things are supposed to be, are completely simple. They're just very crickatured and cartoonish. Now, what you find is that the typical population can decipher their way through this. They know what these facial expressions are supposed to represent,

even if they don't look like that in real life. Autistics are maybe because their experiences are quite complex with how people respond to them starting early in life, and I'm just wildly speculating here, but autism are going to notice that things are more complex and uncertain than that. And again, it's considering more possibilities, and that will very much hamper their task performance if what you are looking for is this sort of automatic certainty

that these acted expressions are sort of all there is, which is not accurate. And that leads to many problems because we're actually training autistic people to ignore the complex, real important information in favor of the cricketered stereotype, simplified, probably wrong information, and we should really think about that.

But that gives you an idea of looking at social deficits, thinking about how autistics process information, and also actually looking at the literature itself. Let me mention a few cognitive skills, and we'll just run through them briefly, but tell me what you think we know about autistics and non-autistics. Chord disaggregation. You hear a chord, and you want to figure out what are the notes inside the cord. What do we know?

So autistics are good at cordisembeding, and that's what that ability is called. Now, this is a great way to bring in the importance of the literature on autistic savants. Autistic savants are the best way to think of them is autistics who are very obvious. So they can multiply large numbers in their head. They can do the so-called... It's very obvious that they are processing information atypically. That makes them very obvious autistics. They are very obviously high variance in their range of abilities,

so there can be quite drastic contrast between things that they are bad at and things that they are excellent at. And this, again, makes them very, very obvious. people, their abilities are extraordinary for anybody. They have difficulty doing quite basic things. So they're very obvious. They've been extremely important in research in spite of the literature on them being tiny. It's disproportionately contributed to what we know. Yet, you know, this extraordinary contribution of these individuals has just been really gets denigrated all the time. That's awful to see. So this is how we know, because autistic savants can disaggregate cords. This is then studied

in less obviously talented autistics who, it turns out, are better at disaggregating chords, cordis embeddings, so Pamela Heaton did work in this area. And my favorite bit in this literature is in a book chapter by Linda Prang, where they tested Derek Paravichini, so he is blind and autistic. Outstanding musician. He's considered intellectually disabled, developmentally disabled, however you want to put it, as they do in the in the savant literature, they test these savants against people who are experts, so expert musicians. And, you know, they conk out pretty quick after five or six notes. They're getting in a lot of trouble.

They can't disembed these chords. They can't tell you which notes. They consist of. And Derek Parvichini kept going. He could do the first chord in Hard Day's Night, perhaps, right? Well, exactly. But, you know, what they said in this, what the researchers here didn't anticipate. And, you know, it's just sort of awful that this isn't reported in a formal paper.

This is in a book chapter. But that it didn't occur to them that they would run out of fingers. You know, they were dated a 10-note chord, and he could still disembat it. And they had not anticipated that they would need someone with more than 10 fingers to properly test the limits of this autistic person's ability. So this is somebody who is a creative, fantastic musician in every sense. But to know that he can do this, I mean, it's almost like almost by accident that we know this, and we have not managed to get to the limit of his abilities here because they just didn't anticipate.

What do you think of the hypothesis that virtually all autistics are in some logical way savants, but there's a socially constructed category of savant that some things, such as multiplying large numbers or doing the calendar trick, whether a particular day far in the future is a Monday or a Wednesday, that is regarded as being a savant. But if you have a quite ordinary skill that you're very good at, like making managerial decisions, no one will call you a savant. But in essence, you're doing the same thing.

Agree or disagree? I'm not going to answer that. I'm going to totally answer a different question, which is that what people should notice, first off, is that savant skills are sort of conglomerated in specific areas. Why might that be, say, music, hyperlexia, drawing in three dimensions, calculation, calendar calculation. Why? Because this is information that tends to be available in most environments and that is often quite hard to take out of those

environments. Now you have to think about that. So people can't take it away from autistics. You can always look at calendars, think of that calendar. They try. So they do now. So this is taking that information away is a feature of many, if not most, popular autism interventions. So that awful. So why, I'm answering the question, why are some people consider savants and some not? First, it is, we don't know anything, we are not interested

in what kinds of information autistics have available to them starting development. So I'm trying to get other people interested in that. It's very uphill. You know, because autistics are maybe specific on how they start to figure out how to, how to

work with the kinds, quantities, and arrangements of information they process well. So let's say an autistic will have access to, say, music, and they will have access to good music and so on, and they will figure that out, and they have access to a piano, which is particularly, seems a particularly good array of information for artistic. This is generally savants, they're not, the musicians, aren't all pianists, but an awful lot of them are, and the piano, all the information is there, right? It's in front of you. It's, it's, It's complex.

It's all there. So this tends to be the kinds of information that Artistics will start with. Now, let's say you have somebody and they figure out music. You know, they figure it out at all levels, you know, from a single note to complex compositions. And this is what savants do. What if they realize then, and it's in their environment, that they can apply this to something else?

And you do get savants that have multiple abilities that used to be considered wrongly, not what happened. But it is what happens. and the idea of an autistic polymath has just not been explored at all. So you get a paper where the autistic person, you're just exploring specific aspects of their extraordinary music ability. You know, you will only mention in passing that there are an outstanding chess player. And we don't know anything more about that.

So that's just an example that is actually in the literature. True or false, autistics often have weaker episodic memory and they're less likely to think in terms of stories, and when they watch movies or read books, they will pick out very different pieces of information and have very unorthodox readings relative to the mainstream. I would say that's very well established, though it is not interpreted that way.

So the way to interpret it is that autistic do not organize information in memory typically. It should not surprise anybody. They do not use narratives to edit things, to organize things, and that means that they perform very differently on episodic memory tasks. And related tests that require people to organize information into sort of common or popular narratives. There are at least two kinds of IQ tests, and autistics do better on one than on the other. and some of your best known research is in this area. Tell us the basic finding.

There are very different approaches to measuring intelligence. One is a battery of tests, as in Waxler scales of intelligence. You are trying to get at general abilities by using an array of different specific tests. So you're trying to get at something latent. So these are just specific abilities. but through those that you come up with some kind of late in general ability that we call intelligence or full-scale intelligence. Or you can take one test with one format that is sufficiently complex and difficult that it gets at the same thing, just with one test. So that would be Ravens Progressive Matrices, a test that has been extremely influential in the entire intelligence literature.

What are those questions look like? Just give us a very direct, intuitive sense. It's a matrix of entries, so the number varies, and you have the last one in the matrix, the last item in the matrix, is missing, and you choose the right one from an array of offered answers. So that's it. It sounds too simple or easy, but it is a very complex test, and a very difficult one. In effect, it's played a large role in defining what general intelligence is. And which tests do autistics tend to do better on and why? So, autistics do better on Raven and quite a bit better. In some individuals, the discrepancy is spectacular. It's a lot. So how they would be judged, and again, go to the savant literature, And this is what influenced me to pursue this.

You'll have an individual in the savant literature who really cannot perform other tests would be judged. It's very intellectually disabled on other tests. Effectively, it doesn't even have, can't perform a receptive language test, much less produced language, and the score is very high on Raven.

So one possibility, I mean, better than most of the typical population, all about it, you know, one or two percent. And again, he had to have the opportunity to do that for us to find that out. So there's a lot of interesting things about that because if you look at what the kinds of deficits that have been assumed that autistics have in processing complex information, in executive functioning, in working memory, in all kinds of complex processes, this is what Raven actually demands. And what was your role in discovering this differential between the two kinds of IQ? tests, your personal role, as a researcher? There was a paper in 2004, and it was one of the first ones I actually kind of looked

out in an editing capacity after it was sort of accepted provisionally. It did find, though, very tentatively that autistics were possibly performing better on Raven than these other tests. And the interpretation in the paper was that Raven wasn't a good test for autistic. It must overestimate autistic intelligence. and I thought first that there are other possibilities and also I looked around at how Raven was being first off I had to look at what Raven was

and how it was being interpreted in the autism literature which says that when autistics performed well on it was almost denigrated as a test this is just visual spatial abilities and so on and you look in the intelligence literature and you have this test that is really central in defining human intelligence that is very important and requires all these abilities that autistic supposedly don't have.

And I thought, well, isn't this worth pursuing? And it did take a lot of persuasion to go in that direction to sort of question the commonplace and typical, and this is typical, the autism literature, autistics perform well on the test. There must be something wrong with the test. Now, before you offered an understanding our conception of what autism is, the definition, but if we get to the nitty-gritty question

of what's the core mechanism or the core difference in autistic brains. Some people have suggested there's some kind of weaker or disabled or maybe more optional form of top-down processing, so there's maybe more direct access to smaller bits of information or greater optionality as to the level at which information is accessed. If you're characterizing of what you think autism actually is in terms of how the information is processed, what do you think of that hypothesis and how would you best

articulate how you understand it. Well, it's my hypothesis, the optionality anyway, so that's me. So I put, I'm maybe not the person you should ask. No, you are the person I should ask. Now, how do I answer that? So this first came out of, you know, these things don't happen in the proper order if you look at the literature. So this came out of it, actually a lovely study done by Isabelle Suleira, who is a PhD student at the time, and she was looking at categorization. So, her field is categorization, and she was looking at how autistic people categorize ellipses.

And the interesting thing about categories is that they distort perception. People will believe that things on either, they will form a category boundary boundary, let's say wide ellipses versus skinny ellipses. And where they put the boundary will mean that they sort of distort how they see those things that are just one side or the other, that boundary, even though the difference isn't any greater than those who are, you know, both on one side and both on the other. The difference between the two is actually the same, but because there has been this sort of division into two different categories. So this is called a discrimination peak, and you notice that it's, because it's found in the typical population, it's not considered a deficit or a bias, it's considered a peak.

Something good. So the question was, do autistics have this peak? And so they were asked to do two things, classify these ellipses, which is, in effect, categorize them. So can they categorize these ellipses as wide or skinny? You can look and see whether they're doing this. and then do they produce a discrimination peak? So the autistic produced this completely typical classification curve. So they formed typical categories when this was the task.

But when they were asked to discriminate one from another, you know, is this tell them apart, they did not show a discrimination peak. That is to say, they were not biased by the category boundary. I sort of leapt in on this because this was considered to be a deficit in category formation. And, you know, I said you can't say that because the autistics, when you ask them to form categories, formed typical categories. You can't form more typical categories than that.

The classification curve was identical. Then you asked them to discriminate. They performed that task. That doesn't mean that they forgot how to categorize. It means that the categorization, they didn't have, you know, that bias was not useful in performing the discrimination task accurately. There came the idea of autonomy. So this means that discrimination was autonomous in the autistics. It was autonomous from categorization. In the typical population, even when it wasn't useful, they formed categories. They had to. So there you have these non-optional categories. They form categories even when it pretty,

biases, even when it wasn't useful for the task. They had to. They had no choice. In the autistics, it was optional. The processes were more autonomous. I've also called this cognitive versatility. It doesn't mean that, you know, again, it doesn't mean the autists can't do this. It doesn't mean that they can't do what might be thought of as top-down processing, what might be thought of as using priors, or what might be thought of as predictive processing, or whatever. it's not that they can't do it. It's that it is not so mandatory or automatic. It is more optional and more versatile. With this optionality, does that mean that on average, autistics are somehow more different from each other than non-autistics are?

When you're, and you see this very striking in the literature and I've just been really, you can see this in the whole predictive processing literature where there's sort of one optimal way to process everything, which is amazing. This is how, you know, supposedly not only, you know, within one person, but across the entire population, you know, there's the premise that there is sort of this optimal predictive inference. You know, that there is one optimal way to process everything. So if you have a hierarchy of information processing that is similar across typical people, and I do believe you have that, I mean, there is some variation, but the hierarchy works in about the same. way. So you would get much more similarity. I mean, it doesn't mean that everyone's similar. They're brought up in different places. They have different experiences. They have different genetics.

They have different, on and on. But they have that greater similarity in what they do with information that will make them more similar in what they do with information and that will give them much more in common. Autistics do not have that, which makes them not just different from typical people, but quite different from each other. This is, I think, being slightly recognized now that autistic people may be more idiosyncratic. This is where it is popped into the literature. There's a fairly new literature with respect to autism on rare copy variants and de novo copy variants in the genetics of autism. What do you think we're learning from these articles? We should be less hasty in deciding things about autistic genetics. I mean, I think that's the

message, you know, we'd ding the seesaw between, we had, you know, the DeNova story was just very, you know, the de novo rare variant story was just a very big deal so that you have an entire collection, you have the Simon Simplex collection, which is just really designed to find these, which were assumed to, you know, if we find these, you know, we will, we will crack autism genetics. But just to clarify, you're saying the literature has shown that autistics are quite different from each other in their mutations? No, that's not what I'm saying. I'm saying autistics will be quite different from each other in,

because those are two different issues, so how autistics process information and the sort of genetics that may lead to brains that work like autistic brains. So I'm not a genetics person, so I do cognitive stuff, but I think the genetic stuff is really a cautionary note of leaping to conclusions that, for instance, you have these sort of rare de novo variants that are the real big deal, and even looking for them in the most favorable circumstance possible, that as you're looking in families that only have one autistic person, they did not find much. But that was the sort of leading story for a long time. We are now, the seesaw is sort of back to common variants,

and we are getting slightly more complicated views that if you have a rare variant, that doesn't mean you don't also have common variants that contribute to how atypical your mind works. So it's been this sort of long slog, but it is a cautionary note against the sort of any simplistic explanation for autistic genetics. And I think we have real problems in...

I think there's been some progress, but I do think we have real problems in, you know, where we've looked, how we've looked. Some of that mirrors just what has happened generally in genetics. In percentage terms, is autism becoming more common or more frequent over time? No. Autism has not become more prevalent. There is no reason to believe that it has. And there, you know, the idea that it has become more prevalent has been sort of very destructive for us. in research and to actual autistic people, since the premise, really what you're saying

when you say that there's been a large increase in autism prevalence is that you are saying older autistics don't exist. That means we can't learn anything from them, you know, including from their early development, from their outcomes, from their achievements. We just sort of totally erase them and write them off. So maybe autistics are being treated worse over time, at least in their roles as children. Is that possible? That is possible, just like it is possible. Again, very hard idea to test, and it's one that I wouldn't even think that I would ever say, but I've said it, and I've even presented about it, is asking whether an autism diagnosis is more beneficial than harmful. Very hard question to

investigate. People have actually one, there is an actual purpose-built study that does that in a way that is, you know, obviously has a lot of flaws, but found that the probable autistics who weren't diagnosed were better off. And in population-based studies, like the one in Korea, the autistics who had not been diagnosed, did not have an existing diagnosis were much better off, you often find that autistics who are diagnosed older at older rather than earlier ages are better off. This is contrary to everything you've ever heard, probably, and so on. I don't think that those things are being taken seriously enough. We definitely are getting data from autistic people who are diagnosed as adults who seem to be better off

than what you find in longitudinal studies of autistics who are diagnosed as children, all very, very hard to interpret, but the question is raised. And the fact that it is out there, and I'm not saying, trying to discuss, encourage or encourage anything or give advice in the least, but it speaks to, I think, my own concerns, and maybe they've been futile, but about standards, basic standards in research and practice, standards of science ethics in medicine. These are things I see as human rights issues. They are, to me, a big deal, and we should be very concerned that we are doing things to autistic people that we know produce bad outcomes in anyone. One of my striking take

from your work. And just to be clear, I don't think you've ever said or written this in general terms, but just to see the extent to which parents do not necessarily have the actual interests of their children at heart, that parents seem to have a strong bias for children who will be a lot like they are, and they will take a lot of steps to try to make their children more like them, even if that in some ways harms the child from the point of view of the child itself. I think of diagnosis as a kind of segregation, and in most other things, settings were morally very reluctant to segregate, but somehow when it comes to children, we seem really quite willing to segregate. This is moral split, so to speak, possibly not always for any good

reason. So first, I'm going to totally disagree about the parents. Keep in mind in autism, we have very, very loud people, loud advocates, loud influential advocates, that does not mean, and those are autistics and non-autistics, professional organizations, people selling services, whatever, very loud advocates. They are not necessarily representative. But they're the most influential group, right? Sure, but you can't. You can't extrapolate from that to parents in general. You just absolutely can't. You know, the literature is different from what you get from the very loud advocates. And of course, you have a lot of autistic parents of autistic offspring. It's still very poorly studied. But this definitely happens. The reproductive fitness, as they call it,

of autistics has been wildly underestimated, I think. This is again, my own view is a non-genetics person. So you have that, but I think you have to be very careful not to confuse advocacy and autism with any group in particular like parents or autistics, for that matter, their views. I think that's a real problem. Now, the segregation thing, I have a massive bias against segregation. See, this may be one place where I'm as an autistic. See, I have an absolute, not just a bias, but I have a profound segregation deficit.

And anybody who's tried to segregate me has going to run into that. So if you try to segregate me, I'm not going to go there. So it should not be segregation. DSM should not be segregation. DSM-5 autism, DSM-A-M-A-Tism is segregation. Why? because the diagnosis segregates autistic people

into lower standards of science and ethics than would be acceptable for anybody else. That's what your diagnosis does. Now, you may be lucky anyway. You may encounter extraordinary individuals who know you're autistic and who will apply good standards of science and ethics to you.

That certainly happens, but you must be lucky. It will not be the kind of kind of more taken for granted where the exception is that you'll be denied these standards. And if you are, there will be recourse. In autism, that is not the case. So to me, that is a segregation. I can't speak to the other diagnoses. I haven't found. I've looked very hard and have not found a situation like you have in autism, where you have these unacceptably low standards that are sort of universally advocated for and that there is no advocacy in the other direction and you have the influence of

advocacy is just completely determinative. As you know, there's a Danish firm called Specialist Sterner, right? And they make a point if hiring autistic people to do things such as programming, is that in your view an instance of possibly unjust or harmful segregation? If you're autistic and you want to be in the workforce in a way that is not very potentially harmful to you, you would be wise to seek out enterprises like this because they are, they shouldn't. So first off, obviously they shouldn't be necessary. Obviously, autistic should be able to go into the workforce like everybody else, be respected for their abilities, not be discriminated against due to their job,

unrelated atypicalities, job irrelevant atypicalities, that is not the case. So you have autistic people who, as employees, are being very much underappreciated and undervalued, and so you have these organizations. And it's sort of, it's very, it's sort of massive. You have these huge efforts to get autistics employed under the sort of umbrella of these sort of, you know, we will test these autistics, we will make sure, you know, we will. You know, we will. We will sort of hire them out to firms. We will get the firms used to having autistics around. We will coach people through things and so on.

And this allows autistics to be in the workforce in a much less precarious way than they would if they simply went out in the world and then had to face this sort of problem of being denied basic rights and standards, which is just a very precarious situation. You may be lucky. But you would have to know it's only luck. no matter how hard you work, no matter how good your work is, your situation is very precarious. Whereas with your sort of under the, you know, I'm trying to think of the right term, you're sort of almost endorsed. You're an endorsed autistic or you have this sort of stamp of approval.

And that sort of indicates to the employer that they should treat you in a certain way. So that will improve your chances greatly and make you sort of much, in a much less precarious situation. and we are more and more sort of, and yes, it is a form of segregation, of saying, yes, this is what we should do to get autistics implied. Now, it's very hard to argue against that in the current situation. If you think of the United States, there's been such a thing as gay identity politics. Those groups have fought for the legalization of gay marriage, and they achieve that.

I would say that's a very good thing. It's spread to many parts of the world, often before the United States. Should there be some kind of comparable identity politics, for Autistics, given that in some ways it has helped gay individuals. Oh, my goodness. So, no, no. Why not? And I'm not even sure. I don't, you know, keep in mind, I think that what, well, first off, I'm going to say what happened gay individuals, what helped gay individuals is having

human rights and the benefit and protection of basic standards and science and ethics. I think that's what autistic are missing, not identity politics. Michelle and I have a co-authored piece on Alan Turing. maybe we'll get to that next time. My last question is on what I call the Michelle Dawson production function. So you know a great deal about autism. How is it that you, given your history, you are not trained as an autism researcher in the formal sense, but how is it that you learn about autism? I had to.

So it came out of my situation being terrible. I was quite motivated. I started by, I had been told over and over again that I was too stupid, no other way to put it, to, understand autism research. I tried other avenues. I was in very difficult situation, legally everything, and really, because I had to address these legal issues and questions, I did actually look at the autism literature and suddenly I had information I could really work with. Suddenly, there it was, you know, this information that I was supposed to be too stupid to work with. And I can tell you that view can continue onwards that I can. I

I'm still too stupid to work with the literature. But what I found is that the information I really needed was in those papers. So I read a lot, a lot of papers. I read a lot of papers. I have not been taught how or what or where to read or anything. I read a lot of papers. I read associated information like trial registration, grant information to get the information as complex and as useful as possible. Michelle Dawson, thank you very much.
