You Are Not So Smart: A Field Guide to the Brain’s Guile

The science of why 600 Facebook “friends” are an illusion, or why brand loyalty is a product of the ego.

We spend most of our lives going around believing we are rational, logical beings who make carefully weighted decisions based on objective facts in stable circumstances. Of course, as both a growing body of research and our own retrospective experience demonstrate, this couldn’t be further from the truth. For the past three years, David McRaney’s cheekily titled yet infinitely intelligent You Are Not So Smart has been one of my favorite smart blogs, tirelessly debunking the many ways in which our minds play tricks on us and the false interpretations we have of those trickeries. This month, YANSS joins my favorite blog-turned-book success stories with You Are Not So Smart: Why You Have Too Many Friends on Facebook, Why Your Memory Is Mostly Fiction, and 46 Other Ways You’re Deluding Yourself — an illuminating and just the right magnitude of uncomfortable almanac of some of the most prevalent and enduring lies we tell ourselves.

The original trailer for the book deals with something the psychology of which we’ve previously explored — procrastination:

And this excellent alternative trailer is a straight shot to our favorite brilliant book trailers:

From confirmation bias — our tendency to seek out information, whether or not it’s true, that confirms our existing beliefs, something all the more perilous in the age of the filter bubble — to Dunbar’s Number, our evolution-imposed upper limit of 150 friends, which pulls into question those common multi-hundred Facebook “friendships,” McRaney blends the rigor of his career as a journalist with his remarkable penchant for synthesis, humanizing some of the most important psychology research of the past century and framing it in the context of our daily lives.

Despite his second-person directive narrative, McRaney manages to keep his tone from being preachy or patronizing, instead weaving an implicit “we” into his “you” to encompass all our shared human fallibility.

From the greatest scientist to the most humble artisan, every brain within every body is infested with preconceived notions and patterns of thought that lead it astray without the brain knowing it. So you are in good company. No matter who your idols and mentors are, they too are prone to spurious speculation.” ~ David McRaney

And in the age of Books That Should’ve Stayed Articles, it’s refreshing to see McRaney distill each of these complex phenomena in articulate, lucid narratives just the right length to be stimulating without being tediously prolix.

You Are Not So Smart is positively one of the smartest books to come by this year — no illusion there.
