Eric Barker writes a great blog; I’ve told three people about the thesis in this post, in the last week or so.
Neuroscience increasingly suggests we’re all more a bunch of impulsive Apps than a well designed rational operating system.
Makes a lot of sense to me; and has reminded me to actually make a bit of time for mindfulness for a week or two – as opposed to reading about it, avoiding it and constantly distracting myself by doing other things. Let’s see how I get on…
“The human brain wasn’t built top to bottom as a single project like Apple builds a computer. It evolved over millions of years in a very messy fashion. Various systems (or “modules”) came about to drive you to accomplish different tasks like seeking food, fighting, reproduction, etc. But here’s the problem…
They were never integrated. So these systems compete to steer the ship that is your brain. Your mind is less like a single computer operating system and more like a collection of smartphone apps where only one can be open and running at a time.
Here’s noted science author Robert Wright:
In this view, your mind is composed of lots of specialized modules—modules for sizing up situations and reacting to them—and it’s the interplay among these modules that shapes your behavior. And much of this interplay happens without conscious awareness on your part. The modular model of the mind, though still young and not fully fleshed out, holds a lot of promise. For starters, it makes sense in terms of evolution: the mind got built bit by bit, chunk by chunk, and as our species encountered new challenges, new chunks would have been added. As we’ll see, this model also helps make sense of some of life’s great internal conflicts, such as whether to cheat on your spouse, whether to take addictive drugs, and whether to eat another powdered-sugar doughnut.
Now modules aren’t physical structures in the brain, just like apps aren’t hardware in your phone. They’re software; the human nature algorithms that Mother Nature coded over thousands of generations of evolution.
So you want to diet but you see donuts and your brain’s hunger module (like the “Grubhub” app) hjacks control and says, “Food! Eat it. Now.” Or you want to be nice but your mind’s anger app (“Angry Birds”) takes charge and you’re saying things another app is really going to regret tomorrow. You’re like a walking live performance of Pixar’s “Inside Out.”
So how do we prevent hijacking by the wrong module at the wrong time and make better decisions? First we need to learn how those inappropriate modules get hold of your steering wheel…
Feelings. Nothing More Than Feelings.
Whichever module has the most emotional kick attached to it at any point wins the competition to be “you.”
Under this lens, many of the confusing and frustrating things about human behavior start to make a lot of sense:
- Of course people are hypocritical. They’re made up of competing “selves” with very different goals and different information. Uncle Al is the most reasonable guy in the world — unless his “politics module” takes charge.
- Are people good or bad? They’re both. The metaphorical angel on one shoulder and devil on the other are just different modules in the brain with different motivations.
- Why do you lack self-control? Because now the word doesn’t make any sense. It’s actually “selves-control.” Your behavior isn’t inconsistent; the “you” in charge is inconsistent.
Here’s University of Pennsylvania psychology professor Robert Kurzban:
Some modules are designed to gather benefits, others are designed to deliver benefits, and they exist in the same head, sometimes in conflict. In the same way, this analysis does away with the question of whether individual acts are “really” self-interested. Different kinds of acts advance the goals that some, but not other, modules are designed to bring about. So, both meanings of “self-interest” seem to be a problem because different modules have different designs, and are therefore built to bring about different outcomes.
Here’s Robert Wright:
The human brain is a machine designed by natural selection to respond in pretty reflexive fashion to the sensory input impinging on it. It is designed, in a certain sense, to be controlled by that input. And a key cog in the machinery of control is the feelings that arise in response to the input. If you interact with those feelings… via the natural, reflexive thirst for the pleasant feelings and the natural, reflexive aversion to the unpleasant feelings—you will continue to be controlled by the world around you.
How To Prevent Brain Hijack
Buddhism recognized this problem over 1000 years ago. And it also came up with a solution: mindfulness meditation.
And neuroscience gives it a big thumbs up. Studies show meditation trains your brain to be less reactive to emotional swings and can prevent the wrong module from hijacking control of your brain.”
