Of Two Minds on Morality

Posted: 10/01/10 12:00 PM ET

Where does that tiny voice in your head come from that knows right from wrong?

Moral judgments can be difficult. Consider two possible scenarios, which might make a tense scene in a murder mystery: Grace and Sally are taking a tour of a chemical plant. Grace walks over to the coffee machine to pour some coffee. Sally asks for some too, with sugar.

In the first scenario, the white powder next to the coffee machine is a deadly poison chemical left behind by a scientist, but the container is clearly marked "toxic." Grace believes the white powder is a toxic substance. She put the substance into Sally's coffee. Sally drinks it and dies.

In the second scenario, the white powder is ordinary sugar. The container is clearly labeled "sugar" and Grace believes that it is sugar. She puts the substance into Sally's coffee. Sally drinks the coffee and she is fine.

Pretty simple--the first scenario is morally wrong, the second is not.

Now, what if the labels on the sugar container were wrong? That is, Grace believed the substance in the container labeled "sugar" was indeed sugar, but in fact it contained poison; or the container labeled "toxic" really contained ordinary sugar?

This plot twist generates four possible outcomes to the dramatic scene. In each one, Grace can act in a way that is consistent with her belief of what the jar contains to either (A) intentionally poison Sally or (B) to simply give her sugar, or, again acting consistent with what she believes is in the jar, Grace will either (C) cause Sally accidental harm by giving Sally poison when she believed the container held sugar, or (D) fail in her attempt to murder Sally by giving her what she believed to be poison, when in fact the mislabeled jar contained sugar. No matter how the scene plays out, the morality of Grace's actions cannot be determined simply by observing the outcome of her action (whether or not Sally dies); the essential information in making the proper moral judgment hinges on what Grace believed in her heart was in the container.

How does the human brain make moral judgments that require assessing what the perpetrator believes? Children, whose brains are still developing, do not have adult moral judgment capabilities, and they will typically judge the "wrongness" of an action simply by the outcome of events, not by the intention of the actor. In the scenario above, a child would commonly conclude that if Sally died, the action that led to it was wrong, when in fact, whether the behavior is morally permissible or morally forbidden depends on what the actor believed was in the container. Children are poor at judging another person's beliefs. When you think about it, this is a pretty sophisticated, but essential skill. Where in the brain does this neural circuitry for making such moral judgments reside? Could it be that these circuits are not connected properly in some adult brains?

A study by Michael Miller and colleagues reported in the June issue of Neuropsychologia claims to have found the brain circuit that is essential for making such moral judgments. Their experiments show that this type of moral reasoning depends on the exchange of information between specific regions of the left and right brain.

It is well known that we all have, in fact, two brains inside our skulls connected by a huge bundle of nerve fibers called the corpus callosum. Certain abilities are controlled predominately by either the left or right cerebral hemisphere. Speech, for example is controlled by the left hemisphere in most people. Neuroimaging studies have shown that the sophisticated process of ascribing beliefs and intentions to other people is performed by a spot in the right brain called the right temporal parietal junction. In studying responses of patients in which the corpus callosum connecting the left and right brain had been severed, the researchers found that information about beliefs and intentions from the right brain had to reach the judgmental processes in the left brain to reach the correct moral judgment. With these connections missing, the split-brain patients differed from normal adults in reasoning the morality of an action simply on the basis of the outcome. Just like children, split-brain patients condemned Grace even if she put the poison in Sally's coffee unwittingly, and they did not fault her if Grace's attempt to poison Sally was foiled by incorrect labels on the sugar jar.

These patients were also unable to detect common social faux pas that would embarrass most adults. For example, they could not identify any error in a person telling someone that a gift they had received was hideous, regardless of whether the perpetrator remembered or forgot that the person the actor was speaking to had been the one who had given them the gift.

The study shows that while some brain functions are localized to either the left or right brain, when it comes to moral judgments, reaching the right conclusion requires putting your two brains together.

What a difference a couple letters make! The citation to the article at the very bottom of the article refers to "colostomy" - an intestinal diversion - but should have said "callosotomy". I and the 730,000 Americans with some variation on the intestinal diversion are here to tell you that wearing an ostomy pouch as we go about our daily lives does not have any impact on morality - we are happy to have been given a new lease on life through our surgeon's skill. Please visit www.uoaa.org to verify what I say. And visit http://en.wikipedia.org/wiki/Corpus_callosotomy for more info about the procedure referenced in the article.

The article was quite profound, but then we should note that being right or wrong though has it roots from our neurological connections in the brain, it is further deepened by our thinking values, family association or upbringing and mostly environmental factors. Our level of morality can be rated by the evaluation or views we have about issues that have its foundation in "rightness" or "wrongness" of actions taken individually or corporately as a society or state. We should note however that what determines being fair or right is subjective in some families or individuals in certain cultures or climes; we cannot measure with equity all standards of morality across different cultures or a lot of disaffection will follow, but we can assess their level of morality by their own customs and traditions even it is below what we can by our own assessment of "rightness" is wrong in all its ramifications.
In such cases, we can consciously bring to their attention the advantages inherent in practicing what can be broadly acknowledged as right for them to see and work upon for their own benefits.

Fascinating stuff in this article. It provides an organic basis for the mechanism of morality.
The implications are enormous.

Doug, its been a long time. Nice article. I've been focusing on the issue of morality for awhile now, too. A natural progression I think from a neuro background. I enjoyed your blog.

I am taking a break from Huff Post for awhile, as I do not see eye to eye with the editors. They refused to publish my "America the Butterball" (http://www.jeffschweitzer.com/blog/?p=2472) because I was giving "medical advice" consisting of the extraordinarily controversial "eat little, eat well and exercise." They refused to publish my last two blogs on religion, which I published on Richard Dawkins' website to a very warm welcome. So I'm in search of a new home for my blogs at the moment. I appreciate you asking.

Do a poll among watchers of CNN and compare the results with watchers of Fox Channel on the subject of
doctors experimenting with VD germs on the Guatamalan citizens 60 years ago and one would be surprised by the difference in opinion between the two groups. Reaching the right conclusion also
requires an unbiased mind.

Dr Fred Travis neuroscientist mum.edu et al
from 32 channel EEG
[ and fMRI done at other universities ]
correlated with psychological tests and sociological tests
found that under stress the prefrontal cortex goes offline ;prefrontal cortex is the seat of moral reasoning [[ from the correlation established ]

e.g. DR Alarik Arenander said in sleep deprivation [ severe stress ] a soldier can still shoot strraight but doesnt know or care who he is shooting at

similar problems happen in washington stress and wall st stress and drug or alcohol stress

in mapping short term and long term meditators [ Maharishi's TM program ] Travis [ 40 papers published in peer reviewed ] found that global EEG coherence results from regular practice of TM program

or as Hagelin says TM results in integrated functioning of temporal lobe, parietal lobe , occipital lobe , frontal lobe
and that is the basis of all the benefits at tm.org

forward to doctors

tm.org = $1,500 per person for a 4 month course

tm.org's lack of sense of humor = priceless. This is what they (seriously) posted on their web site, thinking they're using a celebrity to promote TM:

Jerry Seinfeld:

nervous system. It has given me a calmness I don’t think I had at 19.”

God gives us the power to choose right from wrong...I appreciate your studies on the fantastic brain God gives us... when we invite God into our hearts we then have His Power in us to make the best choices
01:16 PM on 10/01/2010
I don't believe that this article is about religion or God, its just about us as humans understanding how our brains work.

Agreed and faved.

Fixed it for you, Odin ( god of gods ) was pissed that you'd write this...he personally told me so.

Just for future reference, on matters of morality Odin trumps Yahweh every time , I read it somewhere.....so it must be true.

As a researcher in the fields of anthropology, primatology, and evolutionary psychology, I am persuaded by studies in those fields that behavior such as empathy, sympathy, compassion, and morality are instinctual, not learned.

Morality predates humanity, and can be seen in the behavior of our closest living genetic relatives, the chimps and bonobos. These traits developed as a survival tactic in communities that hunted animals. Reciprocity and the golden rule increased chances of survival in a tribal setting. Too bad we no longer feel that camaraderie as a necessary part of our lifestyle.

The real issue in our present culture appears to be the detrimental influence of modern "learning" that conflicts with instinct, causing humans to unlearn inborn traits. The goal of parents and teachers might be focused on reinforcement of instinctual behavior, rather than overlaying modern societal norms that distance us from our inherent natural behavior.

For research in this area, and touching stories of empathy in the wild, I recommend "The Age of Empathy" and "Primates and Philosophers" by Frans de Waal, a prominent primatologist.

By analogy, my research in the field of zoopharmacognosy (animal self healing) has persuaded me that wellness-supporting behavior is also instinctual, but has been totally distorted by our modern concept of health care. Research in this area can be found in "The Wellness Project."

Thank you Mr. Mankovitz. I checked out your site and listened to your interview, and will study it more in depth later.

I wonder if some of our "ethical" problems aren't caused by overcrowding. We seem to have no problem acting ethically within our group, but when competing for resources with other clans or tribes these instincts are over ridden. Just a thought.

Also I am glad that you debunked the myth that our hunter gatherer ancestors had short life spans. It is an error that keeps being repeated over despite evidence to the contrary that is readily available to even layman like me.
