Joseph Weingartner, neurologist:
The condition is what we call an associative agnosia, rather than an apperceptive one. That means it doesn't interfere with one's visual perception, only with the ability to recognize what one sees. A calliagnosic perceives faces perfectly well; he or she can tell the difference between a pointed chin and a receding one, a straight nose and a crooked one, clear skin and blemished skin. He or she simply doesn't experience any aesthetic reaction to those differences.
Calliagnosia is possible because of the existence of certain neural pathways in the brain. All animals have criteria for evaluating the reproductive potential of prospective mates, and they've evolved neural “circuitry” to recognize those criteria. Human social interaction is centered around our faces, so our circuitry is most finely attuned to how a person's reproductive potential is manifested in his or her face. You experience the operation of that circuitry as the feeling that a person is beautiful, or ugly, or somewhere in between. By blocking the neural pathways dedicated to evaluating those features, we can induce calliagnosia.
Given how much fashions change, some people find it hard to imagine that there are absolute markers of a beautiful face. But it turns out that when people of different cultures are asked to rank photos of faces for attractiveness, some very clear patterns emerge across the board. Even very young infants show the same preference for certain faces. This lets us identify the traits that are common to everyone's idea of a beautiful face.
Probably the most obvious one is clear skin. It's the equivalent of a bright plumage in birds or a shiny coat of fur in mammals. Good skin is the single best indicator of youth and health, and it's valued in every culture. Acne may not be serious, but it looks like more serious diseases, and that's why we find it disagreeable.
Another trait is symmetry; we may not be conscious of millimeter differences between someone's left and right sides, but measurements reveal that individuals rated as most attractive are also the most symmetrical. And while symmetry is what our genes always aim for, it's very difficult to achieve in developmental terms; any environmental stressor—like poor nutrition, disease, parasites—tends to result in asymmetry during growth. Symmetry implies resistance to such stressors.
Other traits have to do with facial proportions. We tend to be attracted to facial proportions that are close to the population mean. That obviously depends on the population you're part of, but being near the mean usually indicates genetic health. The only departures from the mean that people consistently find attractive are ones caused by sex hormones, which suggest good reproductive potential.
Basically, calliagnosia is a lack of response to these traits; nothing more. Calliagnosics are not blind to fashion or cultural standards of beauty. If black lipstick is all the rage, calliagnosia won't make you forget it, although you might not notice the difference between pretty faces and plain faces wearing that lipstick. And if everyone around you sneers at people with broad noses, you'll pick up on that.
So calliagnosia by itself can't eliminate appearance-based discrimination. What it does, in a sense, is even up the odds; it takes away the innate predisposition, the tendency for such discrimination to arise in the first place. That way, if you want to teach people to ignore appearances, you won't be facing an uphill battle. Ideally you'd start with an environment where everyone's adopted calliagnosia, and then socialize them to not value appearances.

Tamera Lyons:
People here have been asking me what it was like going to Saybrook, growing up with calli. To be honest, it's not a big deal when you're young; you know, like they say, whatever you grew up with seems normal to you. We knew that there was something that other people could see that we couldn't, but it was just something we were curious about.
For instance, my friends and I used to watch movies and try to figure out who was really good-looking and who wasn't. We'd say we could tell, but we couldn't really, not by looking at their faces. We were just going by who was the main character and who was the friend; you always knew the main character was better looking than the friend. It's not true a hundred percent of the time, but you could usually tell if you were watching the kind of thing where the main character wouldn't be good looking.
It's when you get older that it starts to bother you. If you hang out with people from other schools, you can feel weird because you have calli and they don't. It's not that anyone makes a big deal out of it, but it reminds you that there's something you can't see. And then you start having fights with your parents, because they're keeping you from seeing the real world. You never get anywhere with them, though.

Richard Hamill, founder of the Saybrook School:
Saybrook came about as an outgrowth of our housing cooperative. We had maybe two dozen families at the time, all trying to establish a community based on shared values. We were holding a meeting about the possibility of starting an alternative school for our kids, and one parent mentioned the problem of the media's influence on the children. Everyone's teens were asking for cosmetic surgery so they could look like fashion models. The parents were doing their best, but you can't isolate your kids from the world; they live in an image-obsessed culture.
It was around then that the last legal challenges to calliagnosia were resolved, and we got to talking about it. We saw calli as an opportunity: what if we could live in an environment where people didn't judge each other on their appearance? What if we could raise our children in such an environment?
The school started out being just for the children of the families in the cooperative, but other calliagnosia schools began making the news, and before long people were asking if they could enroll their kids without joining the housing co-op. Eventually we set up Saybrook as a private school separate from the co-op, and one of its requirements was that parents adopt calliagnosia for as long as their kids were enrolled. Now a calliagnosia community has sprung up here, all because of the school.

Rachel Lyons:
Tamera's father and I gave the issue a lot of thought before we decided to enroll her there. We talked to people in the community, found we liked their approach to education, but really it was visiting the school that sold me.
Saybrook has a higher than normal number of students with facial abnormalities, like bone cancer, burns, congenital conditions. Their parents moved here to keep them from being ostracized by other kids, and it works. I remember when I first visited, I saw a class of twelve-year-olds voting for class president, and they elected this girl who had burn scars on one side of her face. She was wonderfully at ease with herself, she was popular among kids who probably would have ostracized her in any other school. And I thought, this is the kind of environment I want my daughter to grow up in.
Girls have always been told that their value is tied to their appearance; their accomplishments are always magnified if they're pretty and diminished if they're not. Even worse, some girls get the message that they can get through life relying on just their looks, and then they never develop their minds. I wanted to keep Tamera away from that sort of influence.
Being pretty is fundamentally a passive quality; even when you work at it, you're working at being passive. I wanted Tamera to value herself in terms of what she could do, both with her mind and with her body, not in terms of how decorative she was. I didn't want her to be passive, and I'm pleased to say that she hasn't turned out that way.

Martin Lyons:
I don't mind if Tamera decides as an adult to get rid of calli. This was never about taking choices away from her. But there's more than enough stress involved in simply getting through adolescence; the peer pressure can crush you like a paper cup. Becoming preoccupied with how you look is just one more way to be crushed, and anything that can relieve that pressure is a good thing, in my opinion.
Once you're older, you're better equipped to deal with the issue of personal a
ppearance. You're more comfortable in your own skin, more confident, more secure. You're more likely to be satisfied with how you look, whether you're “good looking” or not. Of course not everyone reaches that level of maturity at the same age. Some people are there at sixteen, some don't get there until they're thirty or even older. But eighteen's the age of legal majority, when everyone's got the right to make their own decisions, and all you can do is trust your child and hope for the best.

Tamera Lyons:
It'd been kind of an odd day for me. Good, but odd. I just got my calli turned off this morning.
Getting it turned off was easy. The nurse stuck some sensors on me and made me put on this helmet, and she showed me a bunch of pictures of people's faces. Then she tapped at her keyboard for a minute, and said, “I've switched off the calli,” just like that. I thought you might feel something when it happened, but you don't. Then she showed me the pictures again, to make sure it worked.
When I looked at the faces again, some of them seemed ... different. Like they were glowing, or more vivid or something. It's hard to describe. The nurse showed me my test results afterwards, and there were readings for how wide my pupils were dilating and how well my skin conducted electricity and stuff like that. And for the faces that seemed different, the readings went way up. She said those were the beautiful faces.
She said that I'd notice how other people's faces look right away, but it'd take a while before I had any reaction to how I looked. Supposedly you're too used to your face to tell.
And yeah, when I first looked in a mirror, I thought I looked totally the same. Since I got back from the doctor's, the people I see on campus definitely look different, but I still haven't noticed any difference in how I look. I've been looking at mirrors all day. For a while I was afraid that I was ugly, and any minute the ugliness was going to appear, like a rash or something. And so I've been staring at the mirror, just waiting, and nothing's happened. So I figure I'm probably not really ugly, or I'd have noticed it, but that means I'm not really pretty either, because I'd have noticed that too. So I guess that means I'm absolutely plain, you know? Exactly average. I guess that's okay.

Joseph Weingartner:
Inducing an agnosia means simulating a specific brain lesion. We do this with a programmable pharmaceutical called neurostat; you can think of it as a highly selective anesthetic, one whose activation and targeting are all under dynamic control. We activate or deactivate the neurostat by transmitting signals through a helmet the patient puts on. The helmet also provides somatic positioning information so the neurostat molecules can triangulate their location. This lets us activate only the neurostat in a specific section of brain tissue, and keep the nerve impulses there below a specified threshold.
Neurostat was originally developed for controlling seizures in epileptics and for relief of chronic pain; it lets us treat even severe cases of these conditions without the side-effects caused by drugs that affect the entire nervous system. Later on, different neurostat protocols were developed as treatments for obsessive-compulsive disorder, addictive behavior, and various other disorders. At the same time, neurostat became incredibly valuable as a research tool for studying brain physiology.
One way neurologists have traditionally studied specialization of brain function is to observe the deficits that result from various lesions. Obviously, this technique is limited because the lesions caused by injury or disease often affect multiple functional areas. By contrast, neurostat can be activated in the tiniest portion of the brain, in effect simulating a lesion so localized that it would never occur naturally. And when you deactivate the neurostat, the “lesion” disappears and brain function returns to normal.
In this way neurologists were able to induce a wide variety of agnosias. The one most relevant here is prosopagnosia, the inability to recognize people by their faces. A prosopagnosic can't recognize friends or family members unless they say something; he can't even identify his own face in a photograph. It's not a cognitive or perceptual problem; prosopagnosics can identify people by their hairstyle, clothing, perfume, even the way they walk. The deficit is restricted purely to faces.
Prosopagnosia has always been the most dramatic indication that our brains have a special “circuit” devoted to the visual processing of faces; we look at faces in a different way than we look at anything else. And recognizing someone's face is just one of the face-processing tasks we do; there are also related circuits devoted to identifying facial expressions, and even detecting changes in the direction of another person's gaze.
One of the interesting things about prosopagnosics is that while they can't recognize a face, they still have an opinion as to whether it's attractive or not. When asked to sort photos of faces in order of attractiveness, prosopagnosics sorted the photos in pretty much the same way as anyone else. Experiments using neurostat allowed researchers to identify the neurological circuit responsible for perceiving beauty in faces, and thus essentially invent calliagnosia.

Maria deSouza:
SEE has had extra neurostat programming helmets set up in the Student Health Office, and made arrangements so they can offer calliagnosia to anyone who wants it. You don't even have to make an appointment, you can just walk in. We're encouraging all the students to try it, at least for a day, to see what it's like. At first it seems a little odd, not seeing anyone as either good-looking or ugly, but over time you realize how positively it affects your interactions with other people.
A lot of people worry that calli might make them asexual or something, but actually physical beauty is only a small part of what makes a person attractive. No matter what a person looks like, it's much more important how the person acts; what he says and how he says it, his behavior and body language. And how does he react to you? For me, one of the things that attracts me to a guy is if he seems interested in me. It's like a feedback loop; you notice him looking at you, then he sees you looking at him, and things snowball from there. Calli doesn't change that. Plus there's that whole pheromone chemistry going on too; obviously calli doesn't affect that.
Another worry that people have is that calli will make everyone's face look the same, but that's not true either. A person's face always reflects their personality, and if anything, calli makes that clearer. You know that saying, that after a certain age, you're responsible for your face? With calli, you really appreciate how true that is. Some faces just look really bland, especially young, conventionally pretty ones. Without their physical beauty, those faces are just boring. But faces that are full of personality look as good as they ever did, maybe even better. It's like you're seeing something more essential about them.
Some people also ask about enforcement. We don't plan on doing anything like that. It's true, there's software that's pretty good at guessing if a person has calli or not, by analyzing eye-gaze patterns. But it requires a lot of data, and the campus security cams don't zoom in close enough. Everyone would have to wear personal cams, and share the data. It's possible, but that's not what we're after. We think that once people try calli, they'll see the benefits themselves.

Tamera Lyons:
Check it out, I'm pretty!
What a day. When I woke up this morning I immediately went to the mirror; it was like I was a little kid on Christmas or something. But still, nothing; my face still looked plain. Later on I even (laughs) I tried to catch myself by surprise, by sneaking up on a mirror, but that didn't work. So I was kind of disappointed, and feeling just, you know, resigned to my fate.
But then this afternoon, I went out with my roommate Ina and a couple other girls from the dorm. I hadn't told anyone that I'd gotten my calli turned off, because I wanted to get used to it first. So we went to this snack bar on the other side of campus, one I hadn't been to before. We were sitting at this table, talking, and I was looking around, just seeing what people looked like without calli. And I saw this gir
l looking at me, and I thought, “She's really pretty.” And then, (laughs) this'll sound really stupid, then I realized that this wall in the snack bar was a mirror, and I was looking at myself!
I can't describe it, I felt this incredible sense of relief. I just couldn't stop smiling! Ina asked me what I was so happy about, and I just shook my head. I went to the bathroom so I could stare at myself in the mirror for a bit.
So it's been a good day. I really like the way I look! It's been a good day.

From a student debate held at Pembleton:
Jeff Winthrop, 3rd-year student:
Of course it's wrong to judge people by their appearance, but this “blindness” isn't the answer. Education is.
Calli takes away the good as well as the bad. It doesn't just work when there's a possibility of discrimination, it keeps you from recognizing beauty altogether. There are plenty of times when looking at an attractive face doesn't hurt anyone. Calli won't let you make those distinctions, but education will.
And I know someone will say, what about when the technology gets better? Maybe one day they'll be able to insert an expert system into your brain, one that goes, “Is this an appropriate situation to apprehend beauty? If so, enjoy it; else, ignore it.” Would that be okay? Would that be the “assisted maturity” you hear people talking about?
No, it wouldn't. That wouldn't be maturity; it'd be letting an expert system make your decisions for you. Maturity means seeing the differences, but realizing they don't matter. There's no technological shortcut.
Adesh Singh, 3rd-year student:
No one's talking about letting an expert system make your decisions. What makes calli ideal is precisely that it's such a minimal change. Calli doesn't decide for you; it doesn't prevent you from doing anything. And as for maturity, you demonstrate maturity by choosing calli in the first place.
