I stole the title of this posting from an article in the January 2010 issue of Wired magazine.
The Wired article caught my attention because of a new book I’m writing called Brave New Worldview. The main theme of my book is that we generally see the world through the lens of a three-centuries old worldview that is hopelessly inadequate for dealing with many issues we face in the 21st century.
We still define the world in which we live in terms of mechanistic properties framed by Isaac Newton. We especially covet the predictability of Newtonian science. For example, mainstream economics rests on the premise that the twists and turns of markets are generated by people acting rationally in their own interests. This makes it possible to predict t markets with a high degree of accuracy – or so economists have long believed. However as late as midyear 2008 – the year of the great Crash of 2008 – no prominent economist saw the Crash coming.
A review of economists’ record in economic forecasting
reveals a dismal record. Shockingly, former Fed chairman Alan Greenspan told
John Stuart on the Daily Show, “I’ve been in the forecasting business for 50 years.
I’m no better than I was and nobody else is. Forecasting was as good or bad 50
years ago as it is today.”
Newtonian science rests on a platform created by the French philosopher René Descartes. As the founder of the scientific method Descartes proposed that nothing should be considered true until specifically shown to be. He left no room for probability. Something either was or it wasn’t. It was to be or it was not to be. Uncertainty, paradox and discontinuity had no place in science. Yet, as things have turned out, much of our lives now turn on such states. They are at the very core of quantum mechanics, the foundation of contemporary information technology.
Descartes prescribed the steps needed to determine the truth of a proposition. His method precluded any subjective input such as intuition. He called for total objectivity. That can only exist when the data produced by an investigation is always the same regardless of who conducts it. And therein lies the reason I wanted to bring up the Wired article.
The prohibition against nonobjective activities in classic science is so strong that when data in an experiment varies from what the scientist expected he is typically disposed to repeat the experiment multiple times while expecting each time the outcome will conform to his original expectations. Finally, 50 to 75 percent of the “surprise” data is abandoned according to Kevin Dunbar who studies how scientists study things.
Dunbar said, “It wasn’t uncommon for someone to spend a month on a project and then discard all their data because the data didn’t make sense. “
The Wired article goes on to talk about how “psychologists have dismantled the myth of objectivity. The fact is, we edit our reality, searching for evidence that confirms what we already believe. Although we pretend we’re empiricists – our views dictated by nothing but the facts – we’re actually blinkered, especially when it comes to information that contradicts our theories.”
Dunbar has fingered the part of the brain that functions as an anomaly detector. Neuroscientists often refer to this as part of the “Oh shit” circuit. For the neuroscientists reading this it’s the anterior cingulated cortex. When the ACG has been engaged a person looks for the reason for sudden discomfort with an outcome. “Perhaps it’s the method,” they might say. Or they may blame the unexpected results on a machine malfunction.
The absence of an “Oh shit” response by people who don’t already have a mental model of what should happen is why so many breakthroughs in science have been by people working outside their field. For instance, Watson and Crick, the reputed discoverers of DNA were not biologists. It’s a matter of not knowing enough to know what is supposed to happen or having a fear of taking the wrong steps in light of previous experience.
Brain scientists have figured out that the analytical left brain bears a lot of responsibility for rejecting data that doesn’t conform to expectations. So much for left brain objectivity! On the other hand, the emotional (and curious) right brain welcomes anomalous data. It seems that subjective mindedness has a larger role in science than Descartes imagined.
So, the next time you have differences with another person on choosing a course of action try to determine whether your position (or that of your adversary) has originated in the status quo-seeking left brain or in the more adventuresome right brain.
P.S. Be sure to read the Wired article that inspired this post.
