It is like holding an abstract painting upside down; I do not say that the meaning of the picture will suddenly be clear, but some of the structure of the composition that was hidden may show itself’ (p. 1). I came across this after writing my own Necker Cube passage, and was delighted to find the same views expressed by so respected an author. The trouble with my Necker Cubes, and with Bonner’s abstract painting, is that, as analogies, they may be too timid and unambitious. The analogy of the Necker Cube expresses my minimum hope for this book. I am pretty confident that to look at life in terms of genetic replicators preserving themselves by means of their extended phenotypes is at least as satisfactory as to look at it in terms of selfish organisms maximizing their inclusive fitness.
We agree that there is something special about the individual organism as a level in the hierarchy of life, but it is not something obvious, to be accepted without question. My hope is that this book has revealed that there is a second side to the Necker Cube. But Necker Cubes have a habit of flipping back again to their original orientation, and then continuing to alternate. Whatever it is that is special about the individual organism as a unit of life, we should at least see it more clearly for having viewed the other side of the Necker Cube, for having trained our eyes to see through body walls into the world of replicators, and out and beyond to their extended phenotypes. So, what is it that is special about the individual organism?
Yet it is this hard-won fastness that I may seem to be abandoning here, abandoning almost before it is properly secured; and for what? For a flickering Necker Cube, a metaphysical chimera called the extended phenotype? No, to renounce those gains is far from my intention. The paradigm of the selfish organism is vastly preferable to what Hamilton (1977) has called ‘the old, departing paradigm of adaptation for the benefit of the species’. ‘Extended phenotype’ is misunderstood if it is taken to have any connection with adaptation at the level of the group. The selfish organism, and the selfish gene with its extended phenotype, are two views of the same Necker Cube. The reader will not experience the conceptual flip-over that I seek to assist unless he begins by looking at the right cube.

Thanks to the communication context, the brain probably directly activates the “right” meaning, without even considering alternate solutions. A parallel has sometimes been proposed with the Necker cube, the representation of a cube seen in perspective with no depth cue (figure 1). Figure 1 The Necker cube, the famous optical illusion published by Louis Albert Necker in 1832. (Image licensed under CC BY-SA 3.0 via Wikimedia Commons. From https://commons.wikimedia.org/wiki/File:Necker_cube.svg.) The drawing is “ambiguous” in that no cue makes it possible to determine which side of the cube is in front and which side is at the back.

An analogy is often drawn with human perception: on the one hand, the brain analyzes groups of simple items very rapidly in order to identify higher-level characteristics, and on the other hand, it recognizes complex forms from characteristic features, and can even extrapolate a complex representation from partial information (this is essentially what happens in the case of the Necker cube, where the brain infers a three-dimensional representation from a two-dimensional drawing; see figure 1 in chapter 2). In the case of machine translation, deep learning makes it possible to envision systems where very few elements are specified manually, the idea being to let the system infer by itself the best representation from the data.

One of the reasons why most of us think of ourselves as talented, friendly, wise, and fair-minded is that these words are the lexical equivalents of a Necker cube, and the human mind naturally exploits each word’s ambiguity for its own gratification. Disambiguating Experience Of course, the richest sources of exploitable ambiguity are not words, sentences, or shapes but the intricate, variegated, multidimensional experiences of which every human life is a collage. If a Necker cube has two possible interpretations and talent has fourteen possible interpretations, then leaving home or falling ill or getting a job with the U.S.
Or is there something wrong with us? WHEN I WAS TEN YEARS OLD, the most magical object in my house was a book on optical illusions. Its pages introduced me to the Müller-Lyer lines whose arrow-tipped ends made them appear as though they were different lengths even though a ruler showed them to be identical, the Necker cube that appeared to have an open side one moment and then an open top the next, the drawing of a chalice that suddenly became a pair of silhouetted faces before flickering back into a chalice again (see figure 1). I would sit on the floor in my father’s study and stare at that book for hours, mesmerized by the fact that these simple drawings could force my brain to believe things that it knew with utter certainty to be wrong.
But there is another factor of equal importance and greater interest. Like rats and pigeons, each of us has desires, wishes, and needs. We are not merely spectators of the world but investors in it, and we often prefer that an ambiguous stimulus mean one thing rather than another. Consider, for example, the drawing of a box in figure 18. This object (called the Necker cube after the Swiss crystallographer who discovered it in 1832) is inherently ambiguous, and you can prove this to yourself simply by staring at it for a few seconds. At first, the box appears to be sitting on its side and you have the sense that you’re looking out at a box that is across from you.

Since Brewster’s time, entire books—some targeted at seven-year-olds, others at neuroscientists—have cataloged a vast menagerie of optical illusions. Consider the two famous visual tricks, the Kanizsa triangle and the Necker cube. Left: Kanizsa triangle; Right: Necker cube In each case, the eye detects something that is quite literally not there: a white triangle and a three-dimensional box. In each case, it is almost impossible to un-see the illusion. The Necker cube can be visually flipped between two different three-dimensional orientations, but most of us can’t perceive it as it actually is: twelve intersecting lines lying on a two-dimensional surface.
A number of automaton designers in the eighteenth century attempted to create a “speaking machine”—a robotic human head that could utter words and sentences through artificial means, following on the principles of Vaucanson’s automated flute player. But the human ear is not easily fooled by speech simulations: even today, with all of our computational power, a child can tell the difference between Siri and a human voice. And the other senses—touch, smell, taste—are even less prone to being tricked the way our eyes are tricked by the Necker cube. A handful of tactile illusions exist; with taste, the closest equivalent might well be the way chili peppers trick our brains into perceiving heat. But if you want to deceive the senses of another human being, your best bet is to do it through their eyes. There is something paradoxical about this vulnerability.
In a sense, the brain has evolved a series of cheats that enable it to detect things like edges or motion or three-dimensional relationships between objects, filling in missing information on the fly. You can think of these as the rules of thumb that govern our sense of sight. For instance, when our eyes perceive two lines coinciding in a flat image, our brain assumes those lines intersect in three-dimensional space. (The Necker cube relies on this rule to create the sense of depth in the image.) Millions of years of evolution created rules for interpreting visual information, helping the eye evaluate and predict the physical arrangement and motion of objects that it perceives. But through hundreds of years of cultural evolution, we began discovering unusual configurations that would confound those predictions, forcing the eye to see something that wasn’t, technically speaking, there.

My favourite example of this change in consciousness is the brain’s reaction to a sketch of my casino dice. What do you see? At first it appears to be a cube with one square to the fore. But then, as you stare at it, suddenly the cube flips and it seems as if another square is to the fore. Called the Necker cube, the image hasn’t changed but what you are conscious of has. What has happened in the brain? Is consciousness really just a story that your brain tells about the sensory input it receives through the body’s interaction with the world? Another striking example of how the brain processes visual data in surprising ways was shown to me by neuroscientist Christof Koch.
According to Koch’s research, it appears that the retinal nerves are not sending different information, so the change in our conscious experience is happening further down the line in the brain. The trouble is that the fMRI and EEG scanners are too crude to pick up changes as subtle as the flip from one view of the Necker cube to the other. But in 2004 Koch, together with his team at Caltech, spotted an opportunity to ask an individual neuron questions about what stimulated it to fire, which led to the discovery of some curious neuronal activity. THE JENNIFER ANISTON NEURON Epileptic seizures can be caused by a miswiring or scar tissue that is responsible for triggering the synchronized firing of neurons across the brain, a bit like the chain reaction of an atomic bomb going off in the head.
In contrast to the man in the monkey suit, even when you know what is going on it is very difficult to make your brain hear ‘Ba’ as you watch the mouth make the sound of ‘Fa’. The brain is a pattern searcher and is trying to impose structure on the cacophony of information it is being bombarded with. When the information is ambiguous, as in the example of the Necker cube or the McGurk effect, the brain has to choose. These illusions are a warning to all of us trying to know things about our universe. We have no privileged access to reality. Our interaction with our environment is constructed from the information our brains receive, and we build a plausible representation of the external world.

In fact, you can’t control them in the way you can control your deliberate, conscious thought. Insights are like cats. They can be coaxed but don’t usually come when called. The other key feature of insights is that they yield, often literally, a different way of looking at things. Consider the cube on the left side of figure 1.1. This is a Necker cube. The interesting thing about it is that its appearance is ambiguous. As you can see in the right side of the figure, either the lower square or the higher square of this transparent cube could be viewed as closer to you. With a shift of attention, you can see it in either of these two ways. But you can’t see it in both ways simultaneously because the two interpretations are incompatible: a single face of the cube can’t be both closer to you and farther from you at the same time.
But you can’t see it in both ways simultaneously because the two interpretations are incompatible: a single face of the cube can’t be both closer to you and farther from you at the same time. And when you shift your attention from one of these squares to the other, the change in your interpretation is abrupt. This kind of perspective shift is a prototype for insight. FIGURE 1.1: The Necker cube. Wikicommons (commons.wikimedia.org/wiki/File:Necker%27s_cube.svg) The Gestalt psychologists of the early twentieth century liked to point out that we can interpret almost any type of object, situation, or event in more than one way. That’s why people often use expressions such as “seeing things in a new light” or “seeing things from a different angle” to describe insights.
In fact, cognitive psychologists sometimes use the “brick test” as a way to measure creativity: The more frequently you can shift your perspective, the more uses you will be able to think of for a common object such as a brick, and thus the more creative you are considered to be. According to the Gestalt psychologists, when you get stuck while trying to solve a problem it’s often because you are thinking about the problem in the wrong way. Just as a simple visual scene such as a Necker cube can be radically reinterpreted in an instant, so can a complex problem be “restructured,” yielding an aha moment about the solution. An object that was previously used for one purpose can now be thought of as a tool to perform some other kind of task; a threat can now be regarded as an opportunity; a relationship with another person can be redefined from competitor to collaborator.

They can feel the heft and slipperiness of the containers they manipulate with their metal fingers. They know perfectly well where they are and are not fooled into false beliefs by the experience, yet it is as if they were inside the isolation chamber they are peering into. With mental effort, they can manage to shift their point of view back and forth rather like making a transparent Necker cube or an Escher drawing change orientation before one’s eyes. It does seem extravagant to suppose that in performing this bit of mental gymnastics, they are transporting themselves back and forth.” Daniel Dennett, “Where Am I?” in Brainstorms: Philosophical Essays on Mind and Psychology (Hassocks, Sussex: Harvester, 1978), 315.
And yet it is “as if” he was in the place where the operations are unfolding. It is this “as if” feeling that needs to be clarified. It is an “as if” that is not like a belief, but neither is it an illusion. Dennett’s final analogy is a subtle one: the examples that he provides are very specific cases of paradoxical objects. When one concentrates on a Necker cube one can see it now from the front, now from the back, as its back surfaces become its front ones and vice versa, depending on whether one shifts them mentally to the front or to the back. What matters in this analogy with a tele-operator’s experience is not the idea of an interpretative indecidability so much as that of a variation of the objective configuration of the phenomenon as regards the mental focalizing of the subject.
It is a problem that dogs ergonomists who work on the design of interfaces and the psychologists who study the work of tele-operators and how to maintain focal attention for long hours at a time or, as they themselves put it, how to facilitate and maintain the tele-operators’ ” situational consciousness,” which is always fragile: it involves concentrating on one environment even as one is perceiving two; this is a matter of attention and of focusing mentally on one particular point of view. In the case of the Necker cube, you do not see both images at the same time. As soon as you see one, the other disappears. There is a strict alternative here: the one effaces the other. The shift in the point of view is total. But in the case of a tele-operator, although there is a shift between a focal consciousness and a subsidiary consciousness, the problem is that the one continues surreptitiously to feed off the other, for that provides the immediate framework within which the latter is held.

Richard suggested that his move backwards and forwards between the language of gene intentions and the more orthodox language of genetic differences was acceptable because they are simply alternative ways of describing the same thing. To make his point, he described perception of the Necker Cube. The front edges of the line drawing of the cube suddenly flip to the back as we look at them. The lines representing the edges of a cube can be seen as though either the top corner of the cube is facing forwards or it is facing away. Each perceived image of the cube is as real as the other and Richard suggests that, in similar ways, the different pictures of the gene translate backwards and forwards into the other. Both perceptions are equally valid. At first the Necker Cube analogy seems appealing, but it is not exact because the bodies of thought and evidence on which perceptions are based are different for the two ways in which Richard uses ‘gene’.
Nor was I making the vacuous statement that development is complicated. The central point of that passage in my review of The Selfish Gene was to do with the kind of slippage that can occur when language is used loosely. I suspect that Richard believes that he has never been guilty of such slippage for he used the simile of the Necker Cube to refer to the ways it might be possible to move from one type of discourse to another. However, even as clear a thinker as Richard sometimes marches into a linguistic quagmire that causes so much confusion in the minds of others. Richard is aware that he uses ‘gene’ in distinctly different ways.

(Strange inversions will be a major theme in this book.) There seem to be two competing orientations, the first-person point of view of the Defenders and the third-person point of view of the scientists, much like the two ways of seeing the philosophers’ favorite illusions, the duck-rabbit and the Necker cube. You can’t adopt both orientations at once. The problem posed by Cartesian gravity is sometimes called the Explanatory Gap (Levine 1983) but the discussions under that name strike me as largely fruitless because the participants tend to see it as a chasm, not a glitch in their imaginations. They may have discovered the “gap,” but they don’t see it for what it actually is because they haven’t asked “how it got that way.”
The idea of Cartesian gravity, as so far presented, is just a metaphor, but the phenomenon I am calling by this metaphorical name is perfectly real, a disruptive force that bedevils (and sometimes aids) our imaginations, and unlike the gravity of physics, it is itself an evolved phenomenon. In order to understand it, we need to ask how and why it arose on planet Earth. FIGURE 1.2: Necker cube. It will take several passes over the same history, with different details highlighted each time, to answer this question. We tend to underestimate the strength of the forces that distort our imaginations, especially when confronted by irreconcilable insights that are “undeniable.” It is not that we can’t deny them; it is that we won’t deny them, won’t even try to deny them.
The Selfish Gene by Richard Dawkins
Rather than propose a new theory or unearth a new fact, often the most important contribution a scientist can make is to discover a new way of seeing old theories or facts. The Necker cube model is misleading because it suggests that the two ways of seeing are equally good. To be sure, the metaphor gets it partly right: 'angles', unlike theories, cannot be judged by experiment; we cannot resort to our familiar criteria of verification and falsification. But a change of vision can, at its best, achieve something loftier than a theory. It can usher in a whole climate of thinking, in which many exciting and testable theories are born, and unimagined facts laid bare. The Necker cube metaphor misses this completely. It captures the idea of a flip in vision, but fails to do justice to its value.
It is in fact a logical outgrowth of orthodox neo-Darwinism, but expressed as a novel image. Rather than focus on the individual organism, it takes a gene's-eye view of nature. It is a different way of seeing, not a different theory. In the opening pages of The Extended Phenotype, I explained this using the metaphor of the Necker cube. This is a two-dimensional pattern of ink on paper, but it is perceived as a transparent, three-dimensional cube. Stare at it for a few seconds and it will change to face in a different direction. Carry on staring and it will flip back to the original cube. Both cubes are equally compatible with the two-dimensional data on the retina, so the brain happily alternates between them.

A good metaphor is a soap bubble that wobbles in eggy and amoeboid shapes as the tugs among its neighboring molecules pull it into a sphere. Sometimes a constraint network can have mutually inconsistent but equally stable states. That captures the phenomenon of global ambiguity, in which an entire object, not just its parts, can be interpreted in two ways. If you stare at the drawing of a cube on page 107 (called a Necker cube), your perception will flip from a downward view of its top face to an upward view of its bottom face. When the global flip occurs, the interpretations of all of the local parts are dragged with it. Every near edge becomes a far edge, every convex corner becomes a concave corner, and so on. Or vice versa: if you try to see a convex corner as concave, you can sometimes nudge the whole cube into flipping.
What the assumption rules out is a world made up of dust storms, swarms of gnats, fine wires, deep crevasses between craggy peaks, beds of nails viewed point-on, and so on. The assumptions sound reasonable in the abstract, but something still has to find the matches that satisfy them. Chicken-and-egg problems can sometimes be solved with the technique called constraint satisfaction that we met in Chapter 2 when looking at Necker cubes and accented speech. When the parts of a puzzle cannot be solved one at a time, the puzzle-solver can keep in mind several guesses for each one, compare the guesses for the different parts of the puzzle, and see which ones are mutually consistent. A good analogy is working on a crossword puzzle with a pencil and an eraser.
Look at these drawings, designed by the psychologist Edward Adelson. The left one appears to be white cardboard with a gray vertical stripe, folded horizontally and lit from above. The right one appears to be white cardboard with a gray horizontal stripe, folded vertically and lit from the side. (If you stare long enough, either might flip in depth, like a Necker cube; let’s ignore that for now.) But the ink on the page (and the projection on your retina) is virtually the same in the two pictures. Each is a zigzag tic-tac-toe box with some of the squares shaded in. In both drawings, the corner squares are white, the top and side squares are light gray, and the middle square is a darker gray.

The British psychologist Richard Gregory has paid special attention to visual illusions as a means of studying how the brain works. In his book Eye and Brain (fifth edition 1998), he regards seeing as an active process in which the brain sets up hypotheses about what is going on out there, then tests those hypotheses against the data coming in from the sense organs. One of the most familiar of all visual illusions is the Necker cube. This is a simple line drawing of a hollow cube, like a cube made of steel rods. The drawing is a two-dimensional pattern of ink on paper. Yet a normal human sees it as a cube. The brain has made a three-dimensional model based upon the two-dimensional pattern on the paper. This is, indeed, the kind of thing the brain does almost every time you look at a picture.
When we are looking at an actual wooden box, our simulation software is provided with additional information, which enables it to arrive at a clear preference for one of the two internal models. We therefore see the box in one way only, and there is no alternation. But this does not diminish the truth of the general lesson we learn from the Necker cube. Whenever we look at anything, there is a sense in which what our brain actually makes use of is a model of that thing in the brain. The model in the brain, like the virtual Parthenon of my earlier example, is constructed. But, unlike the Parthenon (and perhaps the visions we see in dreams), it is, like the surgeon's computer model of the inside of her patient, not entirely invented: it is constrained by information fed in from the outside world.

If this is the only piece of scientific history you know, you might indeed conclude that all apparent truths are mere approximations, fated to be superseded. There is even a quite interesting sense in which all our sensory perceptions – the ‘real’ things that we ‘see with our own eyes’ – may be regarded as unfalsified ‘hypotheses’ about the world, vulnerable to change. This provides a good way to think about illusions such as the Necker Cube. The flat pattern of ink on paper is compatible with two alternative ‘hypotheses’ of solidity. So we see a solid cube which, after a few seconds, ‘flips’ to a different cube, then flips back to the first cube, and so on. Perhaps sense data only ever confirm or reject mental ‘hypotheses’ about what is out there.16 Well, that is an interesting theory; so is the philosopher’s notion that science proceeds by conjecture and refutation; and so is the analogy between the two.

This phenomenon is a visual perception characterized by unpredictable changes in how the brain spontaneously views patterns that can be considered ambiguous. Probably the most famous pattern is the Necker cube (http://www. hypnosisnetwork.com/articles/a/76/The-Necker-Cube:-An-Experiment-in-Perception)— a line drawing of a cube that does not give any visual cue as to which lines are in front of the others when they cross. The brain prefers to see patterns and images in certain ways based on experiences in life—people view objects from above and not below, light sources come from above and not below, and so on. The unpredictable changes occur the longer a pattern is viewed. As you look at the Necker cube, suddenly your brain will pick up that you could view the cube from below.

Yet Crick’s ambitious aim, as one of the two people who had stumbled upon the secret of life when he and James Watson found the self-copying code of DNA, was to find the seat of consciousness. He wanted to pin down the very structures in the brain that manifested the phenomenon of conscious, as opposed to unconscious, perception. For example, when you see an optical illusion of the kind that flips between one perception and another, such as a Necker cube, there must be some neural change as the flip happens. Where does that neural change occur? Crick never found the answer. On his deathbed in 2004 he was correcting a paper on a structure called the claustrum, which is an especially well-connected sliver of brain tissue that’s hard to experiment on, because it’s so essential.

Sometimes we have conflicting intuitions about something, as many people do about abortion and other controversial issues. Depending on which victim, which argument, or which friend you are thinking about at a given moment, your judgment may flip back and forth as if you were looking at a Necker cube (figure 3.1). FIGURE 3.1. A Necker cube, which your visual system can read in two conflicting ways, although not at the same time. Similarly, some moral dilemmas can be read by your righteous mind in two conflicting ways, but it’s hard to feel both intuitions at the same time. And finally, it is possible for people simply to reason their way to a moral conclusion that contradicts their initial intuitive judgment, although I believe this process is rare.

Each one of us knows we possess it even if, as many modern thinkers aver, it is an illusion – an illusion constructed, as Darwinians might speculate, because a coherent agency of singular purpose helps us to survive. Visual illusions such as the Necker Cube— —or the Penrose Impossible Triangle— —or the Hollow Mask illusion demonstrate that the ‘reality’ we see consists of constrained models constructed in the brain. The Necker Cube’s two-dimensional pattern of lines on paper is compatible with two alternative constructions of a three-dimensional cube, and the brain adopts the two models in turn: the alternation is palpable and its frequency can even be measured.

If the match fits the local region, predictions are passed down the cortical hierarchy in quick succession to all lower regions. If this is a correct interpretation of the stimulus, then each region of the hierarchy will settle on a correct prediction in rapid succession. The same effect should occur while viewing an image with two interpretations, such as a silhouette of a vase that can look like two faces or a Necker cube (an image of a cube that alternately appears in two different orientations). Every time the percept of such an image changes we should see a propagation of new predictions flow down the hierarchy. At the lowest levels, say V1, a column representing a line segment of the image should stay active in either perception of the image (assuming the eyes haven't moved).

The right hemisphere is able to maintain ambiguous mental representations in the face of a tendency to premature over-interpretation by the left hemisphere.445 The right hemisphere’s tolerance of uncertainty is implied everywhere in its subtle ability to use metaphor, irony and humour, all of which depend on not prematurely resolving ambiguities. So, of course, does poetry, which relies on right-hemisphere language capacities. During ambiguous stimulation of perceptual rivalry (the phenomenon of an ambiguous figure that can be seen in one way or another, but not both simultaneously, such as the duck–rabbit above or the Necker cube opposite446) right frontal cortex is more active.447 Fig. 2.13 Is this a cube seen from above right, or from below left? Blurred or indistinct images are not a problem for the right hemisphere, but are for the left, even where the nature of the task would suggest that it should be more problematic for the right hemisphere.448 One of the most consistent early findings in hemisphere specialisation was that whenever an image is either only fleetingly presented, or presented in a degraded form, so that only partial information is available, a right-hemisphere superiority emerges – even when the material is verbal.449 In some subtle experimental work Justine Sergent was able to demonstrate this and its converse, namely that when images are presented for longer than usual, thus increasing their certainty and familiarity, a left-hemisphere superiority emerges, even when it comes to face recognition.

The Necker cube is attributed to a Swiss crystallographer, Louis Albert Necker, who in 1832 described the way in which the structure of crystals appeared to reverse spontaneously. Although the duck–rabbit was made famous by Wittgenstein, it was first discussed by the American psychologist, Joseph Jastrow (‘The mind’s eye’, Popular Science Monthly, 1899, 54, pp. 299–312), who in turn derived it from a German popular magazine called Fliegende Blätter (1892).

What amazed him was how easy it was for the eyes and the brain to be fooled. When, many years later, he became a psychologist, he was interested in the regular mistakes and exercises of “filling in” that our brain makes in order to provide us with a quick picture of reality.

Never mind… You put the anti-tank rifle down and turn around. The ghastly altar is still there. It’s made of pale granite, and it seems to throb slightly as you look at it, as if it’s on the verge of turning inside out like a Necker cube: The hieroglyphs are as alien and incomprehensible as ever, but somehow horrible, bringing to mind echoes of alien anatomy, organs ripped from the abdominal cavities of human sacrifices, and other, hidden things. “Great,” you mutter. “Attention, object able charlie sixteen.

Like many high-tech entrepreneurs, Camp was peculiar. McCloskey noticed that he did not particularly care about the superficialities that absorbed other people. For example, he got his hair cut only sporadically, letting it grow down to his shoulders before having it cut short. He also liked to design his own T-shirts featuring symbols such as a Necker cube, a line drawing that can be perceived in different ways. Then he would wear them out to dinner at nice restaurants. “I have no idea where he got those things,” McCloskey says. “I was not thrilled by them.” He didn’t like to carry cash and would come home and absentmindedly stuff an unwieldy wad of bills into his dresser, then leave it there.

Our eyes don’t present to our brains a faithful photograph of what is out there, or an accurate movie of what is going on through time. Our brains construct a continuously updated model: updated by coded pulses chattering along the optic nerve, but constructed nevertheless. Optical illusions are vivid reminders of this.47 A major class of illusions, of which the Necker Cube is an example, arise because the sense data that the brain receives are compatible with two alternative models of reality. The brain, having no basis for choosing between them, alternates, and we experience a series of flips from one internal model to the other. The picture we are looking at appears, almost literally, to flip over and become something else.

Such people might be less prone to suffer from attentional disorders, and they may experience flow more easily. Dr. Jean Hamilton’s research with visual perception and cortical activation patterns lends support to such a claim. One set of her evidence is based on a test in which subjects had to look at an ambiguous figure (a Necker cube, or an Escher-type illustration that at one point seems to be coming out of the plane of the paper toward the viewer and the next moment seems to recede behind the plane), and then perceptually “reverse” it—that is, see the figure that juts out of the surface as if it were sinking back, and vice versa.

It just doesn’t seem scientific. If you got as far as Recovering_irrationalist—so that many-worlds now seems perfectly logical, obvious and normal—and you also started out as a Traditional Rationalist, then you should be able to switch back and forth between the Scientific view and the Bayesian view, like a Necker Cube. So now put on your Science Goggles—you’ve still got them around somewhere, right? Forget everything you know about Kolmogorov complexity, Solomonoff induction or Minimum Message Lengths. That’s not part of the traditional training. You just eyeball something to see how “simple” it looks. The word “testable” doesn’t conjure up a mental image of Bayes’s Theorem governing probability flows; it conjures up a mental image of being in a lab, performing an experiment, and having the celebration (or public recantation) afterward.
