From the ageist and illiberal abomination that is the 21 drinking age and especially its authoritarian enforcement, to drunk driving, to drug policy, to transportation policy, to environmental policy, to foreign policy, to Tobacco 21, and so on, America has well and truly lost the plot long ago on so many issues. How long ago, you may ask? Well, roughly 40 years ago, if not even a bit earlier than that. But how and why did it happen in the first place? Why can't our "leaders" (and many of those who keep voting for them) ever seem to see the forest for the trees?
In the book, The Master and His Emissary: The Divided Brain and the Making of the Western World by Iain McGilchrist (2009), the author delves into the familiar idea of the left vs right hemispheres of the brain. Only unlike the usual surface-level analysis in that we see in pop neuroscience, this one is a real deep dive into the truly resounding implications of these brain differences for society and civilization. Ten years later, it was even made into a documentary, The Divided Brain (2019), by McGilchrist himself along with award-winning documentary filmmaker Vanessa Dylyn, et al.
To summarize: the two hemispheres of the brain each see the world and process information in fundamentally different ways: the left brain is more reductionistic in thinking, while the right is more holistic in thinking. The left is more logical, analytical and detail-oriented, while the right is more creative, intuitive, and sees the bigger picture. The left is more linear, while the right is more non-linear. The left sees the map, while the right sees the territory. And so on. While both sides are of course quite valuable and necessary, the brain functions best overall when the right brain is in charge. The left is a great servant, but a terrible master, hence the title of the book. And Western culture has, for thousands of years, oscillated between favoring the overall relative dominance of each of the two hemispheres. In recent centuries and decades, as in some other historical periods as well, we have become far too left-brain dominant, with very negative consequences, according to the author. Not only does the left not really know what the right is doing, but at least half the time the left doesn't even know what the left is doing! The left brain has thus essentially hijacked society, and that in turn leaves us "increasingly incapable of grappling with critical economic, environmental, and social issues, ones that shape our very future as a species", as the documentary would put it. I am largely oversimplifying what he said, of course, but that is the basic gist of it overall.
One obvious reason for this excessive left-brain dominance could be due to poorly-designed education, of course. But another could be that the left brain is faster in terms of processing speed than the right, and the pace of life is undoubtedly much, much faster nowadays than even the recent past. Though the latter would be more of a chicken-or-the egg question.
(And to all of the political conservatives and reactionaries who try in vain to shoehorn all of this into their silly left-wing vs right-wing political spectrum, like that one guy on The Daily Sceptic did recently, please get your own ideas. This book, by a renowned Oxford scholar, truly thoroughly transcends such a naive interpretation of politics.)
A-ha! That really explains a LOT!
Clearly, the USA (and a good chunk of the world as well, but especially the USA), has only gotten more, not less, left-brain dominant since roughly 40 years ago. We as a society have been reactively lurching from crisis to crisis, moral panic to moral panic, trend to trend, fad to fad, idol to idol, and propaganda to propaganda, throwing at each whatever left-brained nostrums seem like a good idea at the time without really thinking it through. But try as they may, the map is NOT the territory. And their reductionist "solutions" invariably affect not just this thing over here, but also that thing over there, and that other thing all the way over there, and so on. Oops!
One thing's for sure: As the late, great Buckminster Fuller famously said, you cannot solve a problem with the same kind of thinking that got us into that problem in the first place. Unfortunately, not nearly enough people have gotten the memo, it seems.
UPDATE: Looks like McGilchrist has a sequel to the aforementioned book, titled
The Matter with Things, as well. Food for thought.
A brain divided against itself cannot stand.
