A “selective attention test” can quickly prove this point. I did one recently with a room full of psychology undergraduates, almost all of whom had identified as monists. “Since you guys are the brightest and the best,” I simpered “let’s do a little intelligence test. Apparently only five per cent of the general population get the answer right to this puzzle, but in this room, I expect the success rate will be a little higher…”
Having primed them by flattering their egos, I proceeded to show them a video called “The Monkey Business Illusion”, designed in 2009 by scientists Christopher Chabris and Daniel Simons. During the short film, a group of people pass basket balls to each other, and viewers are asked to count how many times the players wearing white shirts pass the ball. It seems simple enough, and when the film ended, I asked the students how many counted the right number of passes. Almost every hand in the room went up. No surprises there.
Then I asked the more important question – who saw the gorilla? There was a smattering of laughter, and this time only about half of the hands went up. Meanwhile, the other half of my students were looking around at their peers, utterly confused…
But it was true. In “The Monkey Business Illusion”, a person in a 6ft gorilla costume walks right across the middle of the scene, weaving through the players in the game. However, because most viewers are intently focussed on watching the players in white, they simply don’t perceive it. You can try this for yourself - the video I’m talking about can be found easily on YouTube, and if you follow the search term “selective attention test” there are many others like it.
The material point is that the world around us contains significantly more sensory input than our minds can process, so we simply don’t pay attention to most of it. If you pause for a moment right now, you might notice that there is the hum of a heater in your room, or the noise of traffic outside, or the smell of an air freshener, or that a piece of your clothing that is too tight – things you were simply not aware of until I pointed them out. It’s common that we don’t perceive things until something else makes us think that they are important. If someone tells you that your house might have structural damage, you will suddenly start to notice every creak that comes from your walls and ceilings, even though those creaks have probably been happening for years.
As social beings, we can be easily conditioned into paying attention to certain things and ignoring others. If I tell a group of students that intelligent people are highly attentive to the players in white shirts, I increase the likelihood that they simply will not notice a gorilla.
There is good research to show that children, even in our modern and secular society, are inherently spiritual – most young kids believe in God, or gods, fairies and the existence of many things unseen. But this is not celebrated in our STEM focussed education system, wherein young minds are highly conditioned to let go of such “irrational” beliefs and trust in the full explanatory power of science. It is so effective that, by the time they get to my classroom at university, I’ve got little hope of persuading any of my monists that there was a 6ft gorilla without showing the video again and letting them see it for themselves.
But there are always some people who are willing to challenge the idea that Marley was just an undigested bit of beef. There are always some people who attend churches of one type or another, or practice other forms of spirituality and religion. Some pray, some meditate, and many take part in rituals. This trains them in what anthropologist Tanya Luhrmann calls “micro-processes of attending”, leaving them more ready to perceive spiritual things instead of screening them out of their conscious awareness. How they respond might depend on preferred tradition – dancing, liturgy, or a little bit of both. But all agree that there is something going on that is unseen and important.
Many STEM educated, highly rational and fully committed monists no doubt think that those who attend churches are deluded and deceived into perceiving unseen things are simply just not there. These nay-sayers have been taught, implicitly and explicitly, that it is more intelligent to believe in the all-explanatory power of science. But perhaps it is they who have been deluded and deceived? As the Monkey Business Illusion demonstrates, if you flatter someone’s intelligence enough, it becomes entirely possible to hide a 6ft gorilla in plain sight.
