Got Free Will? Yes and No.

October 2, 2014 by Joycelyn Campbell 4 Comments

Do we have free will? To some, the answer is yes, obviously we have free will. Many others say not so fast. It’s a thorny question that has only grown thornier over the past 30 years. That’s because we’re no longer focused so much on whether an external agent or force determines what we do. Now it’s an internal agent or force we’re concerned about—namely the unconscious part of our brain.

It’s probably apparent to most of us that we spend at least part of our time on autopilot—that is, behaving automatically, not consciously registering much of what’s going on around us, or not experiencing a sense of volition or agency. Stimulus A (whether internal or external) triggers reaction B. But the growing consensus of neuroscientists and others is that we spend not only part of our time, but most of our time, on autopilot. Some have tried to make the case that all of our behavior is automatic.

On the one hand, it’s hard to let go of the notion that we have complete control over our every thought, word, feeling, and deed. On the other, that’s a lot of responsibility and a tough row to hoe. The fact that, no matter what we think—or want to think—we don’t always feel in control sets up a conflict we’ve come up with some ingenious methods to resolve.

System 1, our unconscious, keeps us alive, filters what gets into conscious awareness, and initiates most of our thoughts, feelings, and behaviors. System 2, consciousness, very often just goes along with System 1’s recommendations. But not always. System 2 is capable of initiating thoughts and actions on its own, apart from what System 1 suggests. It can also veto System 1’s suggestions.

So one answer to the question about whether or not we have free will is “yes and no.” When it comes to habits, routines, or anything else System 1 is responsible for—when we’re operating on autopilot—we aren’t really acting freely. But when System 2 gives critical attention to System 1’s suggestions and either vetoes or sanctions them—or when System 2 initiates thoughts or actions of its own—we can say that we are acting freely.

There may be no outside agent forcing us to behave a certain way. But since we normally don’t consider the unconscious to be part of “I”—who we think of when we think about who we are—the unconscious feels quite a bit like an “other.” System 1 may be my brain, but it sure doesn’t feel like me.

“Yes and no” seems to be the best answer to the question of whether or not we have free will. It’s important to recognize the situations in which we operate on autopilot because if we think we’re making choices and acting freely when we’re not, we’ll be less likely to look for effective methods to change behavior we want to change, and we won’t be able to see things from any perspective other than our habitual one.

At the same time, if we don’t recognize the situations where we have the capacity to make decisions and act freely, not only will we be in trouble, society and the entire human race will be in trouble, too. Or is this just the norm—part of the human condition?

How Free Is Your Will?

September 4, 2014 by Joycelyn Campbell Leave a Comment

Here are links to a few articles and videos by some of my favorite scientists, researchers, and writers who focus on the brain—specifically on the part of the brain we’re not aware of but which so strongly affects every aspect of our lives.

Of course, much of what is being discovered about how the brain actually works is revolutionary in and of itself. But the access we have to it is no less revolutionary. An internet connection is all it takes to read, watch, or listen to the latest developments. By now, I take that access for granted. But that doesn’t stop me from appreciating it.

Click on the titles to get to the articles.

The Possibilian

David Eagleman, author of Incognito

The brain is a remarkably capable chronometer for most purposes. It can track seconds, minutes, days, and weeks, set off alarms in the morning, at bedtime, on birthdays and anniversaries. Timing is so essential to our survival that it may be the most finely tuned of our senses.

When I came across Incognito on a bookstore shelf, I picked it up because I had read (and torn out) this article from The New Yorker. There’s a local connection, too. Eagleman attended Albuquerque Academy, which is only a few minutes away from where I live. So far, he’s the only scientist I’m aware of who uses the terms alien subroutines and zombie systems to describe our unconscious processes.

How Your Mind Works

Daniel Kahneman, author of Thinking, Fast and Slow

Any video with Daniel Kahneman in it is worth watching. Thinking, Fast and Slow can be a bit of a slog to get through in places (at least if you’re mathematically challenged like I am). But Kahneman’s spoken explanations are disarmingly clear and straightforward.

How Free Is Your Will?

Michael Gazzaniga and Joseph LeDoux

Philosophers have debated for years whether we deliberately make each of the many decisions we make every day, or if our brain does it for us, on autopilot. Neuroscientists have shown, for example, that neurons in the brain initiate our response to various stimuli milliseconds before we’re even aware that we’re taking such an action.

This link includes the video conversation between Gazzaniga and LeDoux along with the song “How Free Is Your Will?” performed by Le Doux’s band The Amygdaloids. The concept of a rock band composed of neuroscientists is mildly mind-bending. But they’re not bad.

Gut Feeling: How Intestinal Bacteria Could Manipulate Your Brain

David DiSalvo, author of What Makes Your Brain Happy, and Why You Should Do the Opposite

We’ve all heard about the bacterial universe within our bodies, but what’s less well known is just how vast this universe is in comparison to the rest of us: bacteria outnumber all of the cells in our body 100 to 1. And just like us, certain bacteria have a taste for certain nutrients, and they’ve developed ways of influencing their hosts to deliver more of their preferred vittles to the dinner table.

Yes, DiSalvo says, your brain may have made you eat that huge piece of chocolate cake. But apparently “the nervous system superhighway that runs from the digestive system all the way to the base of the brain” is a two-way street. What you eat can influence your brain in constructive–or non-constructive–ways.

Is Your Head Ready to Explode?

You might have a head on the verge of exploding if you’re trying to operate under these two incompatible assumptions.

You have free will, and you choose whatever you do or don’t do.

You can’t do or not do a single thing without having a reason.

Our brains have been shown to be highly proficient reason-generating machines. It’s part of their hardwiring for survival. And we seem more than happy to go along for the ride without questioning the process or the result.

Here’s how it goes:

We turn something into a reason.

We act as if the reason has an independent existence.

We impute a direct cause-and-effect relationship between the reason we have created and whatever we do or don’t do.

Maybe we think we freely chose whatever we turned into a reason for a particular action or non-action. But if we have to have a reason in order to act or not act, the reason doesn’t really matter. We still can’t simply act. We still have no power. And ultimately, we still aren’t responsible.

There’s no point in arguing for free will all the while operating as if we live in a deterministic universe in which everything that happens is the result of something that happened before. The mental gymnastics required to maintain these opposing beliefs keep us stuck in the status quo, chasing our mental tails, and sometimes going to extreme measures to defend our lack of power and responsibility.

Which explains quite a lot.

Neuroscience, Buddhism, and the Enneagram

July 15, 2013 by Joycelyn Campbell 7 Comments

Note: A greatly expanded version of this post can be read here.

Current neuroscience research supports the Buddhist belief that we are sleepwalking through life (“budhi” means to wake up), as well as the theory behind the Enneagram that we are all on autopilot most of the time. Although we have the impression that our behavior is consciously chosen, consciousness comprises only a small part of our brain’s activity—and consciousness is both limited and a huge energy hog. The vast majority of our thoughts, feelings, and actions are the result of brain activity we aren’t even aware of.

It can be hard to come to terms with the idea that we’re not consciously choosing every single thing we do. Even if we don’t always like what we’ve done—or at least the results—we want to believe we have freely chosen to do those things. Choice and freedom go hand-in-hand for us, and free choice means we have the ability or power to decide and to act of our own free will. But the reality is that our unconscious rules us to a considerable extent; and there is no way for us to directly access the unconscious.

We evolved this way in order to increase our chances of surviving. If we were forced to consciously think about everything we do, starting when we get out of bed in the morning, we would quickly deplete our brain’s reserves of conscious attention. Then, when a situation arose that required conscious attention, we wouldn’t have any left to devote to it. The expression “brain dead” aptly describes this state.

When we’re “brain dead,” our brain hasn’t really stopped functioning. We probably can’t solve a tricky problem or plan a complex project or learn and retain new information. But our unconscious is still operating just fine. It can get us home while looking out for any potential danger, take us through the operation of familiar kitchen appliances or drive-through restaurants to get us fed, and make sure we complete our regular bedtime routines.

Those are the kinds of things our unconscious does best. It’s always looking out for us, which is a very good thing. However, it has much more influence over us than we’re aware of, and it’s been influencing us our entire lives. After decades of believing we’re running the show, it can be tough—and initially alarming—to recognize how little control we actually have.

Yet, waking up to this state of affairs and figuring out where to find the autopilot switch is the only chance we have of actually gaining some control. Neuroscience is now giving us an opportunity to take a peek under the hood, so to speak. It’s fascinating to me. The research supports what I’ve been aware of ever since I was introduced to the Enneagram nearly 20 years ago–and what Buddhism has been telling us for centuries.
