Brain Structure Differs in Liberals, Conservatives: Study

WASHINGTON — Everyone knows that liberals and conservatives butt heads when it comes to world views, but scientists have now shown that their brains are actually built differently.

Liberals have more gray matter in a part of the brain associated with understanding complexity, while the conservative brain is bigger in the section related to processing fear, said the study on Thursday in Current Biology.

"We found that greater liberalism was associated with increased gray matter volume in the anterior cingulate cortex, whereas greater conservatism was associated with increased volume of the right amygdala," the study said.

Other research has shown greater brain activity in those areas, according to which political views a person holds, but this is the first study to show a physical difference in size in the same regions.

"Previously, some psychological traits were known to be predictive of an individual's political orientation," said Ryota Kanai of the University College London, where the research took place.

"Our study now links such personality traits with specific brain structure."

The study was based on 90 "healthy young adults" who reported their political views on a scale of one to five from very liberal to very conservative, then agreed to have their brains scanned.

People with a large amygdala are "more sensitive to disgust" and tend to "respond to threatening situations with more aggression than do liberals and are more sensitive to threatening facial expressions," the study said.

Liberals are linked to larger anterior cingulate cortexes, a region that "monitor(s) uncertainty and conflicts," it said.

"Thus, it is conceivable that individuals with a larger ACC have a higher capacity to tolerate uncertainty and conflicts, allowing them to accept more liberal views."

It remains unclear whether the structural differences cause the divergence in political views, or are the effect of them.

But the central issue in determining political views appears to revolve around fear and how it affects a person.

"Our findings are consistent with the proposal that political orientation is associated with psychological processes for managing fear and uncertainty," the study said.

    • Our world is created in opposites: good/bad, hot/cold, up/down etc. The opposite of love is fear. This creates a bit of a problem then, since so many of these wrongwingers clam the mantle of Christianity and Christianity is supposed to be about loving your neighbor (like yourself) and that God is everywhere and creates everything. So there in lies the problem - God is love and creates everything in his/her image in this love - how, then, can there be an opposite of love?

    • A finding that shows liberals are good at directing combative situations from an armchair, and that conservatives are good at actually handling the situation while the liberal sits their ass in the chair? Shocking.

      See how I interpreted that to suit my own conclusion? Pull your collective heads out of your asses, for the love of all that is good and logical.

      I'd love to hear your reasons for making such a claim, and I would further love to hear how you justify being open minded and understanding of complexities (as per the article) when you flat-out reject and aggressively attack any views contrary to your own.

      "Only opinions that support my own are important." That is the charge you are making with that comment. Truly an impressive point of view.

      I never said the words that you quoted. You'd like to hear my reasoning? My reasoning for what???? Stating that you don't support civil rights for all humans?

      Gays deserve civil rights. I don't have to accept your beliefs, because your beliefs are flat-out WRONG regarding the issue. Please, tell that to a former slave or a woman in the early 1900s who was denied the right to vote. YOUR position regarding civil rights is indefensible.

      Who said anything about gay rights? You seem to be associating conservatives with homophobia. Is that association based on anything in particular? Some might say conservatives are the first in line to stop government from regulating marriage, but you seem quick to jump to the idea that those who think same sex marriage is wrong is also wrong--possibly because if that view was legally enforced it would create a frightening situation for you/? What about the fact that all people can vote now: minorities, women, even gays?

      i think he thinks your a conservative, based on the fact that you don;t think the article proves that conservatives should be at all considered relevant in the voting process since they are against human rights, and thus you don't believe in human rights either.

      ****I**** brought gay rights into this conversation based on your statements, and based on our prior discussions about gay rights. You're against gay rights. So I'm relating that fact to your comments here.

      Not too hard to figure out!

      His views regarding homosexuality & gay rights, although he has the right to express them, are flat WRONG. And I'm here to remind him of that fact.

      If you are also against gay rights, you are equally WRONG.

    • What this all means in layman's terms is; the portion that controls fear is more active in the day to day decisions of conservative minded individuals. More fear = fox news. Black and white concepts need to be had for this type of ignorance to thrive. Taking the time to accept uncertainty breeds open-mindedness and patients. These are the qualities shown in the structure of the brain for more liberal tendencies. Religious &"God fearing" vs. Open to the Unknown. Now there are plenty of folks who exist in the middle and aren't part of some extreme dichotomy, but businesses like Fox don't market to nitch markets.

    • Hearing a lot of conservatives with anterior cingulate cortex envy, and yet liberals seem unthreatened by larger right amygdalas in conservatives. Once again, conservatives MUST HAVE EVERYTHING THEIR FUCKING WAY.

    • Watching self identified liberals skew the suggestions of a scientific study to reinforce a non-liberal attitude toward "others."

      By all means vote this down. IDGAF cause its true. Liberalism is not a sports team. Stop treating it like one.

      I don't know this is an article about a study. I can be open minded about the whole thing but then again I can't draw to much from a study I haven't read.

      "Are there no "others?" "A" does not equal "non-A" does it?"

      I'm not against the idea of people being fundamentally different or physically predisposed to certain ideologies. I just think the way this idea was applied by a lot of current members is simplistic, absolutist and at the same time contradictory.

      I'd argue a world view or personality is an amalgamate of a lot of little stuff and whatever inference we can draw from a single aspect of that individual is negligible. If not I think we'd of figured out the human condition by now.

    • Seriously? If you believe this story, you may need to be scanned to see if you have a brain yourself. This is completely retarded. "Liberal" and "Conservative"
      are subjective viewpoints and can not be quantified objectively.

    • A liberal study showing that conservative brains are less tolerant, or dare I say it, more reptilian. Of course this is biased because liberals like all that sciency stuff. Maybe they should do a study that involves gut instinct or just asking God outright. Then we would have a balanced analysis.

    • Of course the liberal brain is different, it is damaged and full of "hope and change" Plague that prevents the liberal from seeing Obama as anything other than a messiah, even when he goes against everything the liberals stand for. Liberalism is a mental disorder.

      If you believe Obama goes against everything liberals stand for, why do you continue to portray him as a super-lefty? Inconstency doesn't help your argument. As it happens some of us believe he has been playing way too nice with the dictatorial House denizens, as he was doing earlier when Democrats had the majority in both houses. When you extend a hand of bipartisanship and the other side keeps whacking it with a ruler, you should get a clue and get on with business. It may have escaped your notice that Obama last week appointed Jeff Immelt, big dog at GE,to head his innovation and jobs committee, all smiling and enthusiastic and full of compliments. This was right after he said he was going to go after corporate tax evaders. As you may also know, GE paid zero taxes last year. In some cases he's carrying out YOUR agenda, not ours. Pay attention, don't generalize, and you'll feel a lot better.

      Maybe Obama didn't want to impose his beliefs, as that would be much too frightening, electing to organize opposing viewpoints into productive dialogue instead, and using the "captains of industry" to run the machine...

    • I remember reading about this about 9 mnths ago or so. It makes a lot of sense. I have said it before and will repeat. The problem is in the center. Their are a lot of people who are brainwashed to think there are two sides to every issue; however common sense that makes, it doesn't when you are talking about a lot of things. You wouldn't argue the flat earth thing, or the 6000 year old earth thing, or many others. This though are things that can be used to confuse people. Take evolution for example, who in their right mind could even remotely think evolution is not as demonstrable as gravity. Nevertheless, you have a group of people who want to cling to the superstition that they are gods special little toys, saying well I understand the science enough and will take the health benefits associated with evolutionary studies, even though I'm not sure about evolution. In politics it is the same. You know abortion in a land of liberty is about personal choice, plain and simple; yet, you have people confused enough about the actual statistics and meaning to think its murder. These issues are all known media infotainment infrastructure brainwashing techniques. If a good argument can confuse you, you are in the middle; however, you must still take a stand. Taking stands is what we HAVE to do. Remember, the corporatocracy, political infrastructure, and infotainment industries want you in the middle and confused so they can distract you from their crimes against all life and planet!

      Its the independents--shit gets too conservative, then too liberal, then too conservative... No one is ever good enough so they quit switching sides. Once they figure out who actually helps them they'll probably stop switching. America is a pendulum swinging back and forth. Also, whoever has the most (homeschooled) children ends up having the most votes in 21 years...

    • I've long said that humans seem to be hard-wired to the right or left (though a conversion happens from time to time--these people would be a great addition to this study). If you look at it anthropologically, it's adaptive to have both ways of looking at a problem. But if we start turning on each other rather than working together, we endanger ourselves and everything around us. Not so long ago, U.S. congress used to have periodic ice cream socials. That sounds so ridiculously prissy and simplistic, but it was a way of getting those on opposite sides of the aisle to socialize, relax, have casual exchanges with colleagues rather than opponents. Work got done and there were friendships across the aisle. Now, only enmity and perhaps the hard-wiring getting harder. Most definitely NOT adaptive. I vote, probably unpopularly, for the return of at least the figurative ice cream social.

      Bush on golf course right after 9/11: " Al Quaeda is a bad terrorist group and we're going to go get them [or words to that effect] Now watch me take this shot."

    • Yep.

      I've posted similar articles before, and been attacked by people with large amygdalas for doing so.

      There are a number of studies, both biological and psychological, that show the innate diferences between the two.

      People think of liberalism and conservatism as political ideologies, but they are far more than that- they are world views, like pessimism and optimism.

      This also explains why religion and conservatism have a strong correlation- both are based on fear of uncertainty.

      Atheists and Agnostics are not afraid to say there is stuff about the universe we just don't know.

      Religious people want to pretend that there is some uniting structure or plan maintained by an omnipotent caretaker because that makes them feel beter.

      2012 as the uniting structure--it is a religious belief in a point of time that offers uncertainty (transformation to what...?) AND complexity. Fear and hope.

      If you BELIEVE it will happen in the near future, it's a BELIEF.

      It is impossible to scientifically verify the future.

      It is only scientifically verifiable after the fact- like all of the previous doomsday dates and beliefs about the second coming that have come and gone with no event at all.

      All we have about the future is probability- such as the fact that it is highly probable the sun will rise tomorrow, and there will be a new day.

      The second coming ranks as an incredibly low probability- especially since there is no definitive proof of a first coming, and the source of the information has proven to be unreliable on previous occasions.

      There is no logic to your reply at all- not even the slightest bit.

      As I said, we have the concept of probability.

      If there is a probable negative outcome, OF COURSE things should be done to prevent it.

      No rational human being thinks the future is carved in stone and is verifiable to us in the present, and no rational human being would use that fact as an argument to suport inactivity.

      Turns out my mother was right!
      Therefore I will try to refrain from calling republicans stupid.

      I don't know. Maybe you're being somewhat sarcastic, but I tend to think that's a dangerous way of thinking about it--that conservatives "biologically can't help it." As others have said, there are those who flop sides. My parents did in their late 40's. Acting as if something is unfixable creates only a problem of bigotry and leads really only to greater polarization--for it's not as if conservatives would acknowledge a study like this anyway, and just submit.
