Male anglerfish are born with an innate desire to not exist. As soon as a male reaches maturity, he acquires an urge to find a female, sink his teeth into her, and grow into her. This evolved because anglerfish live in the dark ocean abyss with few mating opportunities. By giving up his life to be part of the female, the male can reproduce more often. It’s not clear he can appreciate all the sex he’s getting, however, because much of his body and brain atrophies and fuses with her body. Nevertheless, that’s where male anglerfish want to be – that’s a full male anglerfish life. And you thought you had problems. At least you’re not partially absorbed in someone else’s abdomen. Let’s toast our fortune: We are not male anglerfish!
Or are we? Although we have no innate drive to stick our heads into the sides of other people, we do have a drive to stick our heads into groups of people – into communities, tribes, villages and clubs. We’re social primates, and a full human life is centered on the communities we’re in, and our place within them. There aren’t many hermits, and most that are probably wish they weren’t. Communities of people have bulls-eyes on them that are irresistible to us humans. Although communities are necessary for a full life – e.g., family, bowling league, and civil war reenactment society – there are some communities that are especially damaging to one’s creative health. Creative communities – they are the creativity killers. For scientists, for example, their female anglerfish is the community of scientists, a community which is creative as a whole, but which tends to snuff out the creativity of individuals within it. Not only are these creative communities dangerous to one’s creativity, but they seductively attract creativity-seeking individuals into them like moths to a creativity-scorching flame.
That creative communities are alluring to the aspiring creativity maven is not surprising: we all want friends who understand what we do and appreciate our accomplishments. What is surprising, and is not widely recognized, is the extent to which these creative communities are destructive. The problem for the male anglerfish is that his entire world becomes shrunken down, from a three-dimensional world of objects and adventures to a zero-dimensional world of gamete-release. The problem for us is that we’re equipped with a brain that, upon being placed within a community, reacts by severely shrinking its view of the world. Once the psychological transformation has completed, one’s view of the world has become so radically constricted that one cannot see the world beyond the community.
The source of this shrinkage is something called “adaptation,” or “habituation.” When you walk from a bright sunny street to a dimly lit pub, the pub initially feels entirely dark inside. After a while, however, your eyes habituate to the low light level, and you see it as highly varied in light level: it looks dark inside that mouse-hole in the wall, bright where the uncovered light bulb is, and, scattered around the room, you see dozens of other light-levels spanning the dark-light range. This is clearly advantageous for you, because you effectively began as blind in the pub, and minutes later could see. In order to make it happen, though, you underwent a kind of “world shrinkage,” in particular a kind of “luminance shrinkage,” where luminance refers to the amount of light coming toward your eye from different directions around you. When you first entered the pub, all the differing luminance levels in the pub were treated by your visual system as pretty much the same, namely “very very dark”; at that point in time your eyes were habituated to the wide world of luminances found on a sunny day outside. The “sunny” world of luminances differs in two respects from the “pub” world of luminances. First, the average luminance in sunny world is much higher than that in pub world. Second, and more important for our purposes here, sunny world has a much wider range of luminances than in pub world – from the high luminance of a sun-reflecting car windshield to the low luminance of the gaps in a sewer grating. Our eyes have the ability not only to adapt to new light levels (e.g., high versus low), but also to new levels of variability (e.g., wide versus narrow). When you habituate from sunny world to pub world, your eyes and visual system treat the tiny range of luminance levels found in pub world as if they are just as wide as the range of luminances found in sunny world. Your entire perceptual space for brightness has shrunk down to apply to what is a miniscule world in terms of luminance. This kind of world shrinkage is one of the many engineering features that make mammals like us so effective. All our senses are built with these adaptation mechanisms at work, and not just for simple features like luminance or color, but also complex images like faces.
In fact, our heads are teeming with world-shrinking mechanisms that go far beyond our senses, invading the way we think and reason. When we enter a creative community, varieties of adaptation mechanisms are automatically elicited inside us, helping to illuminate the intellectual world inside the community. Ideas within the community that were impossible for us to distinguish become stark oppositions. Similar mechanisms are played out for our social world – the hierarchies we care to climb, and the people we care to impress. At first we don’t appreciate the status differences within the hierarchy, even if we abstractly know them; but eventually we come to “feel” the gulf between each tier. While having these mechanisms is fundamental to our success in tribes, and was thus selected for, our creative integrity was not on the evolutionary ledger. Creative communities are dank pubs, and once we’ve optimized ourselves to living on the inside, our full range of reasoning is brought to bear on a narrow spectrum of ideas, a spectrum that we’re under the illusion is as wide as it can be. And so we don’t realize the world has shrunk at all.
