Brain Differences In Liberals and Conservatives

i_like_spam writes "Scientists from NYU and UCLA report in Nature Neuroscience that the brains of Democrats and Republicans process information differently. This new study finds that the differences are apparent even when the brain processes common information, not just political topics. From the study, liberals were more likely to be accurate and showed more brain activity in the region associated with analyzing conflicts. A researcher not affiliated with the study stated, liberals 'could be expected to more readily accept new social, scientific or religious ideas.' Moreover, 'the results could explain why President Bush demonstrated a single-minded commitment to the Iraq war and why some people perceived Sen. John F. Kerry... as a flip-flopper.'"

    Please don't start with the socialist thing. Americans do not know what "socialism" is and they've co-opted the word to use as an insult. Much like "Liberal" and "Conservative" are no longer definitions of political ideology but epithets. In this black and white world of false political dichotomy there is no room for moderates and there is no understanding of any political ideology outside of those espoused by the two faces of the single American political party (Republicans & Democrats).

    In much the same way that religious voters will tolerate massive corruption and sexual perversion from politicians who claim deep religious convictions (of the White Anglo Saxon Protestant variety only please) . American's will tolerate outright evilness on the part of the avowed anti-communist & anti-socialist capitalist businessmen and lobbyists.

      I am not in the middle of this Liberal/Conservative "war," and I can tell you honestly that liberals can be very stupid, and conservatives can be very astute. I think that's the wrong way to draw conclusions from this study (the implied conclusions to which you're posing your counter-argument).

      I think the correct conclusion would be that a strikingly even line is drawn through our population. One half freely (to an extent) accepts new information when it's presented. The other half is resistant to new information, and favors information that is older and more established.

      I'd suggest that this is an evolutionary imperative. You need the free-thinkers who are going to provide your edge against the environment and potential rival species / groups. You also need the stability of consistent choices when change turns out to be temporary. For example, if a new source of food appears which has more nutritional benefit, you want to be able to adapt to that, but you want to also resist constantly selecting new foods, as this retards the development of specialized farming / gathering capabilities.

      The use of the word "accurate" in the summary is highly questionable, however. I'll have to read the full article when I have time to understand what they mean by that.

    Exactly. However, a lot of the ranting about Kerry "flip-flopping" seems to be trying to suggest that sticking to an idea, no matter how cretinously stupid and harmful, is the most important thing and changing your mind in the face of a changing situation is bad and wrong.

  9. Is accepting every new random idea a good thing? by jofny · · Score: 4, Insightful

    Most people here assume just accepting new ideas at face value (which is all the study suggested) is a good thing. The article did not in any way indicate that it tested what the evaluative processes that liberals vs conservatives go through before they integrate new ideas into their view of the world. That's a critical thing to know. Frankly, I want people in charge and those voting to have some initial skepticism and to analyze new ideas before they accept them. Just because you hear it or have an initial thought doesn't make it true or valid.

    On another note, the article indicated that they chose "very liberal" or "very conservative". It's entirely plausible that the extremes are there for biological reasons and those who dont "identify" with their political orientation choose that orientation for different reasons (former biological, latter rational thought)

    I guess it goes without saying that democratic politics seems to be something less than the shining beacon of leadership it's meant to be, at the moment. The "left" and the "right" seem to rarely argue from their traditional perspectives anymore (left: more tax, more public services, more rights for gay people and women; right: less tax, more freedom for corporations, "family values") and instead just stick to the party drift. Right: pro-war; left: anti-war.

    In the UK, we even have the leader of the right wing Conservative party (David Cameron) saying he will match Labour's spending commitments. There is now nothing to choose between them in terms of policy. The only difference is whichever set of politicians you think is the least idiotic and selfish.

    In the US, I guess it's whether you're more sickened by the corruption and incompetence of the Republicans or the cowardice and lack of direction of the Democrats.

    That's precisely what drove me crazy about the whole Kerry thing. Granted, Kerry wasn't the best candidate. By far. But being able to reason out various thoughts and change your decisions if the situation merits it is a sign of intelligence. Repeating the same thing over and over is something I'd expect a kid with autism to do, not a President or any other politician.

    Actually, the inevitability of becoming more conservative as we age is overstated, at least from my observations.

    However -- there is something of a tendency this way, which is readily explained by something market researchers have known for years: the concerns of young people and old people are different.

    When you are young, you don't have much: not much stuff, not much property, not much power. But you have potential. Therefore you favor things that take wealth out of the hands of The Man in order to maximize human potential.

    When you are my age, you have lots more stuff, lots more power, but less margin of error. The twenty year old who loses everything has his entire work career to earn it back. The fifty year old can look forward to a miserable retirement. Therefore you are less interested in exploiting the possibilities of a brave new world, and more interested in holding onto what you already have.

    I would say that the most intellectually committed individuals on the right and left tend to shift less often than the people whose ideology is a shallow "stick it to the man" thing. The latter people's opinions really just reflect their selfish immediate interests throughout their lives.

    In the short term, in America, "right-wing" and "conservative" overlap.
