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?

Why All the News Is Bad: Our Negativity Bias

September 16, 2014 by Joycelyn Campbell Leave a Comment

negativity-bias

Our brain’s own hardwiring for survival makes us vulnerable to stress and anxiety. It evolved to quickly detect threats in the environment and sound the alarm: time to fight or flee now! When we were facing multiple life-or-death threats a million years ago, it was definitely better to err on the safe side. If we reacted to something that didn’t turn out to be a real threat, no significant harm was done. But if we failed to react to something that did turn out to be a serious threat, it could mean the end of us.

The unconscious part of our brain was all about survival a million years ago, and it’s still all about survival today. Although the world we live in has changed radically, our brain has a ways to go to catch up. Operating at a much faster speed that we can consciously keep up with, making connections and seeing patterns that might or might not be there, the unconscious brain signals red alert at the slightest indication of trouble, setting into motion a cascade of physiological effects.

Sometimes this works for us, keeping us safe from actual harm; however, there are far more false alarms than real ones. And we pay a heavy price when this threat-detection system runs unchecked. It’s at the root of what is called the negativity bias. It’s why we notice, react to, and remember negative events to a much greater degree than we do positive ones.

The brain is like Velcro for negative experiences but Teflon for positive ones. –Rick Hanson, Ph.D.

System 1: Danger, Danger, Will Robinson

Our unconscious shrugs off neutral or positive news or experiences, sometimes barely registering them, and hones in on the negative stuff. We have a stronger emotional reaction to negative stimuli, which increases the likelihood we’ll remember it. It takes less time for negative experiences to get stored in memory than for the positive experiences, which means our unconscious has more negative memories to draw on than positive ones when it’s evaluating information. And negative experiences affect us longer.

As a result, we are extremely sensitive to perceived or apparent threats. These days, those threats are less likely to be to our immediate survival. But that doesn’t make any difference to our brain. We react just the same whether the threat is to our ideas and beliefs, to our physical or emotional well-being, to our self-esteem, or to a freedom we hold dear.

We all have the same hardwiring. We are all primed to pay attention to the negative. At this point in time, the danger we’re facing is less a result of threats from the environment and more directly a result of our negativity bias. Whether in our intimate relationships, our international relations, or our personal health and well-being, the actual and potential costs of operating from the negativity bias are enormous.

So what can we do?

System 2: Belay that Order

One thing we can’t do is eliminate the negativity bias. It’s up to evolution to modify our perception of and reaction to threats. Hopefully that will happen before it becomes a moot point.

What we can do is develop an awareness of our predisposition to pay attention to and accentuate the negative. We can use System 2—our conscious attention—to:

Notice the negativity bias in ourselves. It’s not easy to be aware of a cognitive bias in the moment, so often the noticing occurs after the fact. But that’s OK. If we continue paying attention, we’ll get faster at spotting the negativity bias in action. We’ll be less at the effect of it.
Notice the negativity bias in others. The point isn’t to call other people out on it. We’re all operating on autopilot most of the time, and when we’re on autopilot we don’t think things through. If we’re aware that someone else is operating from the negativity bias, we don’t have to get caught up in the fear. We don’t have to react.
Ask: Is there a real threat here or only a perceived threat? Once we become familiar with how the negativity bias works, we can develop the habit of evaluating our reactions and calming ourselves.
Intend to pay attention to positive events and experiences. Yes, our attention naturally goes to the negative, but we can train ourselves to focus on positive things. We can intentionally include more pleasure, joy, and laughter in our lives.

Just because we have a negativity bias doesn’t mean we have to give into and continue feeding it. Let’s keep reminding ourselves that more often than not the threat really is all in our head.

A Case for Lucid Waking

September 7, 2014 by Joycelyn Campbell 4 Comments

lucid dreaming

You have to hand it to humans. As a species, we are seriously and committedly wrong-headed about so very many things. And we have a high level of confidence about our beliefs and convictions regardless of how much or how little that confidence is warranted.

For example, we think we’re aware (we understand what’s going on) while we’re awake, so it isn’t that much of a leap for some of us to want to be aware of our dreams while we’re dreaming. A Google search for “lucid dreaming” brought up about 673,000 hits, whereas a similar search for “lucid waking” brought up about 10,200. I’m surprised there were that many.

Reportedly, the person who coined the term lucid dreaming—Frederik van Eeden—considered lucid to be synonymous with mental clarity. And therein lies one of the problems. Mental clarity is sorely lacking in the waking lives of most people. This is a fact, not an indictment. We spend most of our days operating on autopilot, at the effect of biases, triggers and cues, and mental processes we have no conscious knowledge of. Most of what’s going on around us is happening outside our awareness. However, we don’t let that diminish our sense of certainty.

We’re very good at coming up with plausible sounding explanations for behavior and events. But just because we can come up with explanations doesn’t mean they’re accurate. Our stories and explanations are developed after the fact to create a cause-and-effect stream that feels like real life. We don’t do it intentionally—at least not usually. It happens automatically, with no effort on our part. It’s how we make sense of the world. Our stories and explanations provide us with a false sense of complacency, comfort, and security. They give us the illusion of mental clarity but not much of the real thing.

And it’s from this vantage point that we set out to develop mental clarity—or the illusion of mental clarity—about our dreams.

My thought is that we might want to redirect our efforts toward lucid waking. If, as a species, we developed greater mental clarity about how we operate while we’re awake, we might be able to take a stab at solving some of the serious problems we face. That seems like a more practical and worthwhile focus for our attention.

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.

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.

What’s the Condition of Your Metacognition?

August 17, 2014 by Joycelyn Campbell 2 Comments

Metacognition is the awareness of our own thought process and the ability to make judgments about our thoughts. Another way to describe it is “thinking about thinking.” Although this is an abstract concept it has very practical implications.

Metacognition is how we identify our limitations and compensate for them. –Stephen M. Fleming, Scientific American Mind

In order to identify our limitations (as well as our strengths), we need to be able to assess them objectively, yet it can be difficult to be objective about ourselves. We have a tendency to feel confident about many things, but often that confidence is unwarranted. It’s part of the human condition. And, as Dan Ariely has said, “Thinking is difficult and sometimes unpleasant.”

Some of us have better metacognitive skills than others, and metacognition can be impaired as a result of mental illness or substance abuse. But most of us can develop the ability to observe and reflect upon our thinking. We can get better at metacognition.

One way to do this is to maintain an attitude of curiosity. Notice when your assessments turn out to be accurate and when they don’t. You’re likely to find that your thinking is more accurate in some areas than in others, which is the case for most people. If you begin to recognize some patterns, you’ll have a better idea of when your confidence is justified and when it isn’t. It’s much easier to be objective—as opposed to judgmental—when we’re able to be curious about everything that’s happening.

We all analyze our inner thoughts and feelings, but some of us feel anxious about what we might discover about ourselves while others feel intrigued and fascinated about ourselves. –Alain Morin, Science & Consciousness Review

Meditation is another means of developing insight into your thinking process. Regular meditation leads to changes in the brain that seem to be linked to metacognitive abilities.

Metacognition is one of the ways in which we come to know ourselves. The better we know ourselves, the likelier we are to make sound decisions, understand and connect with other people, and identify and achieve meaningful goals.

The practice of self-observation begins with a desire and resolution on your part: “I want to know what really is, regardless of how I prefer things to be.” –Charles Tart, Waking Up
