My Take: Keep government out of mind-reading business

Editor's Note: Paul Root Wolpe, Ph.D., is director of Emory University’s Center for Ethics.

By Paul Root Wolpe, Special to CNN

(CNN) - “My thoughts, they roam freely. Who can ever guess them?”

So goes an old German folk song. But imagine living in a world where someone can guess your thoughts, or even know them for certain. A world where science can reach into the deep recesses of your brain and pull out information that you thought was private and inaccessible.

Would that worry you?

If so, then start worrying. The age of mind reading is upon us.

Neuroscience is advancing so rapidly that, under certain conditions, scientists can use sophisticated brain imaging technology to scan your brain and determine whether you can read a particular language, what word you are thinking of, even what you are dreaming about while you are asleep.

The research is still new, and the kinds of information scientists can find through brain imaging are still simple. But the recent pace of progress in neuroscience has been startling and new studies are being published all the time.

In one experiment, researchers at Carnegie Mellon looked at images of people’s brains when they were thinking of some common objects – animals, body parts, tools, vegetables – and recorded which areas of their brains activated when they thought about each object.

The scientists studied patterns of brain activity while subjects thought about 58 such objects. Then they predicted what the person’s brain would look like if researchers gave them a brand new object, like “celery.”

The scientists’ predictions were surprisingly accurate.

Many scholars predicted as recently as a few years ago that we would never get this far. Now we have to ask: If we can tell what words you are thinking of, is it much longer before we will be able to read complex thoughts?

In another experiment, researchers at the Max Planck Institute of Psychiatry in Munich, Germany, sought out a group of “lucid dreamers” - people who remain aware that they are dreaming and even maintain some control over their dreams while they sleep.

The researchers asked the subjects to clench either their right hand or left hand in their dreams, then scanned their brain while they slept. The subjects’ motor cortex, the part of the brain that controls movement, lit up in the same manner it would if a person clenched their left hand while awake – even though the actual hand of the sleeping subjects never moved.

The images revealed that the subjects were dreaming of clenching their left fists.

Throughout human history, the inner workings of our minds were impenetrable, known only to us and, perhaps, to God. No one could see what you were thinking, or know what you were feeling, unless you chose to reveal it to them.

In fact, the idea of being able to decipher what is going on in that three pounds of grey mush between our ears seemed an impossible task even a couple of decades ago.

Now, for the first time in human history, we are peering into the labyrinth of the mind and pulling out information, perhaps even information you would rather we did not know.

Neuroscientists are actively developing technologies to create more effective lie detectors, to determine if people have been at a crime scene, or to predict who may be more likely to engage in violent crime.

As the accuracy and reliability of these experiments continue to improve, the temptation will be strong to use these techniques in counter-terrorism, in the courtroom, perhaps even at airports.

And if brain imaging for lie detection is shown to be reliable, intelligence agencies may want to use it to discover moles, employers may want to use it to screen employees, schools to uncover vandals or cheaters.

But should we allow it?

I believe not. The ability to read our thoughts threatens the last absolute bastion of privacy that we have. If my right to privacy means anything, it must mean the right to keep my innermost thoughts safe from the prying eyes of the state, the military or my employer.

My mind must remain mine alone, and my skull an inviolable zone of privacy.

Right now, our right to privacy – even the privacy of our bodies – ends when a judge issues a warrant. The court can order your house searched, your computer files exposed, and your diary read. It can also order you to submit to a blood test, take a drug screen, or to provide a DNA sample.

There is no reason, right now, that it could not also order a brain scan.

Right now, the technology is not reliable enough for the courts to order such tests. But the time is coming, and soon.

Eventually, courts will have to decide whether it is allowable to order a defendant to get a brain scan. There is even an interesting question of whether forcing me to reveal my inner thoughts through a brain scan might violate my Fifth Amendment protection against self-incrimination.

But not even a court order should be enough to violate your right to a private inner life. The musings of my mind and heart are the most precious and private possessions that I have, the one thing no one can take away from me.

Let them search my house, if they must, or take some blood, if that will help solve a case. But allowing the state to probe our minds ends even the illusion of individual liberty, and gives government power that is far too easy to abuse.

The opinions expressed in this commentary are solely those of Paul Root Wolpe.

    A country that blindly follows a president like 'Dubbya' into an insanely expensive and completely useless war like Iraq will allow a 'little privacy invasion' in exchange for 'security'. And a country that keeps corrupt congressmen in office who allow businesses to selling details of our private interests, desires and relationships with minimal restrictions or oversight under the pretext that it 'creates jobs' or that 'companies naturally do what is best for us all because it's in the company's best interests' is going to have a hard time dealing with technology that is even more invasive. The sad part is, mind-reading technology will never be applied to the ones who should be watched... the law-makers.

      But all problems will evaporate like unicorn tears if we just elect evangelicals like Perry. Remember when Dubbya was in office and Gawwwwwwwd was Uhmurika's co-pilot. I'm just sayin'.

    all hype, can they tell the difference when they say box and i think about a wooden box vs card board one hummm rofl NOOO. This is like super subjective stuff. What instead of a lie detector test they will do a brain detector test? lol I could probably think of something while they ask.

    If science will be able to detect thoughts – memories – , how can they distinguish between memories and fantasies. It seems to me they both come from the same place and work the same way .

    SITUATIONS make people think and act in a certain ways. For example, if you are robbed and now broke, your mind will think of ways to get out of that situation because survival is the root of all thought. If a person is in such a bad situation, people will resort to crime to survive. Living in a jail cell is better than dying, there might be a chance to get out. With the banks currently causing fraud, it trickles down to the people who are paying life changing events to survive while the banks get a small fine of the money the stole (cost of business). This is the thing that is really not fair and should not be controlled by the government. A person with money (who made it honestly and was not frauded) will have better thoughts than others. Everyone is born innocent. Situations (events) in our lifes create our thoughts and they should not be held against anyone, for we are all trying to survive and make a good life.

      PS. Also, watch that the media doesn't make you think their way only. Are the polls they take really reported correctly? Maybe we should do a vote count on those like in the elections.

    This is amusing. We really don't even have much of a clue how the molecular basis of learning works, but a couple of generalized fMRI images somehow means we can read minds? Far from it. If this is the 2010 published study I'm thinking of, it was actually a comparison of humans to monkeys in how they pick out certain objects from their visual field (probably why he failed to link the study in his story). Obviously this is written by an ethics guy and not someone actually involved in the field.

      Also, Emory has a hell of a neuroscience research program which includes work with primates (rather than just lab mice). I'm sure his colleagues there are banging their heads on their desks this morning.

    I don't really see a danger here. First, the ability to actually read thoughts is very, very far off; the authors examples don't even come close to such a feat. Even if it becomes possible, thinking about something is not illegal; only actions can result in charges being brought. I expect that these technologies, like polygraphs, will remain inadmissible in court for a variety of reasons, although – again, like polygraphs – they may find a role as props used in interrogation theater to intimidate the suspect.

      So when your feeling threatened and thinking of defending yourself while the (interrogators) are leaning on you now you are tagged as prone to violence and you spiral slowly down. You are correct thinking is not a crime (Yet), but what the author promotes is the objective of precognition through this research and that is not good and not safe for humans.
      Someone pointed out that these people in government cannot even balance a budget and this is true. Do you want these same fools to be at the controls of thought reading and deciding if you are good or bad? Consider some of the most corrupt and unethical people in the nation (government officials) will be deciding if your thoughts are OK?

    What do you mean "allow"? What a hoot! If they can, quite simply they will. Our "rights", quite recently have gone by the way of the dodo, i.e. extinct. If you believe for one second that if this technology was available and we could stop the government from using it with a mere law, I believe that you are delusional.

      More enslaved is the word you were looking for not sincere. You really want to sit and tell me you've never wanted to knock someone out, but didnt because it was not right, or felt threatened and thought of what you would do to defend yourself, but did not have to? So now you thought it and now you are tagged as prone to violence? So everyone is a criminal and the instinct to defend yourself becomes a possible future crime.
      This whole idea is bad it is all bad and no good will ever come of it NONE. It's sole purpose will be for abuse and oppression. Imagine the thoughts of the people who control this technology who are above it.
