evolutionyou.net | you are not so smart Recently, my friends at TLC asked me to review David McRaney’s new book, 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. I’ve always agreed with Socrates’ quote—As for me, all I know is that I know nothing—so the title of the book got my attention.

Blogger-turned-author, David McRaney, is a journalist who writes about how deluded we all are. He’s not simply a cynic, though. He tells us that we are all delusional, but also tells is that it’s OK and our delusions actually keep us sane. Davis’s book is like a psychology class, but with all the boring parts taken out, and with no homework. 😉

You Are Not So Smart collects more than 46 of the lies we tell ourselves everyday, including:

  • Dunbar’s Number – Humans evolved to live in bands of roughly 150 individuals, the brain cannot handle more than that number. If you have more than 150 Facebook friends, they are surely not all real friends.
  • Hindsight bias – When we learn something new, we reassure ourselves that we knew it all along.
  • Confirmation bias – Our brains resist new ideas, instead paying attention only to findings that reinforce our preconceived notions.
  • Brand loyalty – We reach for the same brand not because we trust its quality but because we want to reassure ourselves that we made a smart choice the last time we bought it.

One of my favourite of the “lies” in the book is called the Normalcy Bias. The lie or misconception that most people have is that our fight-or-flight instincts kick in and we panic when disaster strikes. The truth is that most people actually become abnormally calm and pretend that everything is okay during a crisis. I had doubts about this idea, but David clearly illustrates the point through a couple examples.

  1. A small town gets warning of an incoming tornado. Instead of getting out of the way or seeking cover, many people choose to do nothing and lose their lives.
  2. An airplane that has just landed gets struck by another airplane also attempting to land. The top half of airplane one is torn off, a few passengers unbuckle & crawl out on the wing and to safety.  But many of the passengers sit stunned in their seats. The airplane explodes. Again, the decision to do nothing costs them their lives.

The Normalcy Bias is just one of many fascinating examples that shed light on why we do what we do. It’s a great read, especially if you are interested in human behavior or if you simply strive to be a know-it-all. 🙂

  1. When my ex-husband and I would go hiking in the mountains, I would tell him when he was being a little reckless, “You know, we’re the people who wind up stranded on a cliff with a broken leg! But I’m smart enough to know how stupid I am!”

    Please count me in. Thank you!
