"Minority Report:" Is There Such A Thing As Free Will?

In the Tom Cruise movie, “Minority Report,” Tom plays a “PreCrime” Captain named John Anderton who apprehends criminals based on foreknowledge provided by three psychics called "precogs". The movie examines whether free will can exist if the future is set and known in advance.

I thought the movie was an interesting fantasy. After all, I believe that we have the power to choose our lives in spite of our circumstances and that we can create any future we choose regardless of our past. I’ll bet you’re a believer too.

I’ve subscribed to the philosophy of Joseph Campbell, the expert on how myths shape our lives, who encouraged us to “follow our bliss” and, in doing so, the world would cooperate in having us fulfill our dreams.

Now I’m not so sure. Welcome to the future.

In his book “Free Will” (which makes a strong case that we don’t have any), Sam Harris cites two experiments. In the first, the physiologist Benjamin Libet used EEG imaging to show that a person’s brain registers a future action we are going to take some 300 milliseconds (enough time for a basketball player to get off a shot before the buzzer) before we actually move.

And a good thing, too. Imagine if we saw the driver of the car in front of us suddenly jam on the brakes and we had to take the time to consciously decide whether to stop or not before hitting our brakes. Our brains save us from accidents almost every time we drive. This explains how we can drive without consciously thinking about driving and still respond to an emergency.

In the second experiment cited by Harris, subjects were asked to press one of two buttons when they saw a letter appear. Now get this: The experimenters found two brain regions that contained information about which button the subjects would press a full 7 to 10 seconds before the decision was consciously made.

The implications of these studies suggest that it’s possible for someone (say a “PreCrime Captain” if there were such a person in real life) to accurately predict our behavior before we behave. How can we claim to have free will when someone can detect what we’re going to do before we know we’re going to do it?

Blows your mind doesn’t it? If we are not acting out of choice (free will), what is giving us our actions? If we don’t have free will, can we hold the murderer responsible for murder, the bully responsible for bullying, the smoker responsible for his “choice” to smoke or the obese person responsible for his/her weight?

In an article by two professors of psychology and neuroscience in the July 27^th, 2012 New York Times (“Did Your Brain Make You Do It?”), the writers ask not only about the implications of these studies to our understanding of whether someone is truly responsible for a crime, but also for ordinary activities like “maintaining exercise regimens, eating sensibly and saving for retirement.”

They conclude by saying “It’s important that we don’t succumb to the allure of neuroscientific explanations and let everyone off the hook” even as neuroscience is suggesting that we have to let everyone off the hook.

But how then to explain the fact that people do lose weight and keep it off, decide to stop smoking and do so or commit to having a loving marriage and maintain that pledge til death do them part?

Good question.

Harris addresses this dilemma but doesn't really answer it. What he does say is that we still can hold others (and ourselves) responsible for their actions, but we must be compassionate when doing so.

As he writes in his book, ”Speaking from personal experience, I think that losing the sense of free will has only improved my ethics—by increasing my feelings of compassion and forgiveness and diminishing my sense of entitlement to the fruits of my own good luck.”

So the next time you go off a diet, become angry even though you want to be kind or procrastinate when you know you should "just do it," forgive yourself. You could have made a different choice but you had no free will to do so.

It's a paradox we'll just have to live with for now.
