by Michael Shermer

If you've got a party that needs spoiling, Michael Shermer is your guy.

Michael Shermer's
The Believing Brain

This is not to cast Shermer with nefarious motives. I doubt the well-known skeptic and founder of the magazine of that name seeks to ruin anyone's fun with his latest work of analysis, The Believing Brain. The author is simply a man of science, and wishes everyone else could be, too.

But I must admit to feeling twinges of disappointment and sadness while I read Shermer's latest. I remember how much fun I had as a kid, reading books about hokum like the Loch Ness monster, Bigfoot, sea serpents, and ghosts. That stuff was, as Denzel Washington's Training Day character Alonzo Harris put it, "bullshit...but entertaining bullshit." Much as folks of all ages spice up their dull as dishwater lives with the imagined possibilities of science fiction, so too the more colorful products of pseudo-science help us retain a bit of that childlike wonder, some semblance of a belief that there's more to the world around us than the banality of everyday life.

To be fair, The Believing Brain is not simply a debunking report on those characters of our dreams (and not a few nightmares). Shermer has attacked such targets in previous works, notably the earlier book, Why People Believe Weird Things. This current work serves up a straightforward examination of how the human brain works; it is a discourse on the cognitive processes that lead us believe ideas both common, ordinary and demonstrable (that sound in the bushes might be a dangerous predator, so watch out) and odd, outrageous and unprovable (the aliens have already arrived and are ruling the world from behind the scenes). Shermer makes his strong case that, contrary to intuitive thought, our beliefs come first, then we use our cognitive biases to reinforce those beliefs, until we find ourselves well convinced of our hold on the "truth."

All well and good, for the psych student. But such discourse does not necessarily make compelling reading for the casual observer. Though Shermer is by now a seasoned pro at writing interesting, accessible, and often humorous prose, parts of The Believing Brain can be difficult to connect with. Some readers will find it easy to get lost in the author's descriptions of the various parts of the brain and their various functions in perception and belief building. While Shermer's account of his personal journey from believer to skeptic is instructive and quite readable, his descriptions of "patternicity" and "agenticity" may prove too technical for many to understand. Reading the early sections The Believing Brain gives you the distinct impression that you're slogging through a bunch of details in order to get to "the good stuff" later in the book.

There are, in fact, pieces of "good stuff" in the book's latter pages. Particularly intriguing is the discussion of Galileo's discoveries at the end of the Middle Ages, and how the reliance on authority so prevalent at the time led otherwise intelligent observers not to see the very objects so readily apparent in Galileo's telescope. (The story suggests obvious parallel's to today's conservatives--current society's arch-lovers of authority--and their obstinate disbelief in evolution, climate change, etc.) And Shermer's account of the debates among astrophysicists regarding the nature of the universe--arguments that ultimately led to Hubble's cosmological discoveries--stands as an eloquent exemplar of the value of the scientific method.

So you can learn a lot reading The Believing Brain. Particularly, you will learn a lot about the author himself. How the reader responds to the ideas presented in the book may depend not upon empirical evidence, but upon how you feel about Shermer. It's hard not to view Shermer himself as part of this equation; the book is littered with the author's imprimatur regarding his subject matter. Many terms of the discourse are categorized as "what I call..." terms; i.e., "we practice what I call 'agenticity'." One suspects that many of the terms so labeled in the book are not necessarily of Shermer's own coinage. Plus, numerous concepts in the text are fleshed out through examples from the author's own experience--particularly when it allows Shermer to recall one of his television appearances, or the marathon bike race he founded and participated in, or to educate his audience about his preference for libertarianism. In fact, a reader could readily draw the conclusion that the one thing Michael Shermer truly believes in is Michael Shermer. That perspective must necessarily color the reader's judgment of the arguments presented in The Believing Brain. Is that shading enough to invalidate the concepts presented in the text? Not in this reader's view; Shermer's arguments retain their validity, based on their own strength. But it's easy to see others having their judgment thrown by the author's somewhat obtrusive personality.

Overall, The Believing Brain succeeds on its own terms. It may not be everyone's cup of tea, but the strength of the scholarship and reasoned argument it presents is not easily refuted. If we all read this book, and were moved to question our own deeply held beliefs--even for a few moments--that would probably be a good thing.
