Kevin Dutton — Black-and-White Thinking: The Burden of a Binary Brain in a Complex World

Several million years ago, natural selection equipped us with binary, black-and-white brains. Though the world was arguably simpler back then, it was in many ways much more dangerous. Not coincidentally, the binary brain was highly adept at detecting risk: the ability to analyze threats and respond to changes in the sensory environment — a drop in temperature, the crack of a branch — was essential to our survival as a species. Since then, the world has evolved — but we, for the most part, haven’t. Confronted with a panoply of shades of gray, our brains have a tendency to “force quit:” to sort the things we see, hear, and experience into manageable but simplistic categories. We stereotype, pigeon-hole, and, above all, draw lines where in reality there are none. In our modern, interconnected world, it might seem like we are ill-equipped to deal with the challenges we face — that living with a binary brain is like trying to navigate a teeming city center with a map that shows only highways.

Shermer and Dutton discuss:

  • black-and-white thinking in: physics, biology, psychology, politics, economics, society,
  • What are categories and why do we need them?
  • When does a hill become a mountain and how many grains of sand makes a heap?
  • from quantitative scaling to qualitative categories,
  • analogue vs. digital, vinyl records vs. DVDs,
  • What is a species, exactly?
  • How can there be dozens of genders if there are just males and females?
  • Abortion: where do you draw the line?
  • from categories to stereotypes to bigotries,
  • tribalism, xenophobia, & racism: the dark side of black-and-white thinking,
  • the difference between a cult, a sect, and a religion,
  • What constitutes mental disorders? Are we all a little crazy?
  • Consciousness: when do the lights come on?
  • When is a Republican a conservative and not a liberal?
