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.'"

    I'm a liberal and I've always had great difficulty convincing Republicans that I'm right and they are wrong. Thankfully this study tells me that it is because I am smart and they are stupid. Since I am white and male, I look forward to further studies proving women and other races are also inferior to me to explain why they are similarly disobedient. Soon, I hope we shall return to the happy days of the 19th Century where science explained why some people the rulers and others are the ruled. Perhaps we could have a rule where Republican votes count for 3/5ths of Democrat votes, like we did with Negros before the Republicans stirred things up. Or perhaps they could be barred from voting completely, like we used to do for women.

    I also hope that when the country has universal health care it will be be possible to abort fetuses with these cognitive disabilities, just like we do for babies with other developmental defects.

    No, just kidding. This looks like awful science, just like the 19th Century studies that confirmed the experimenter's prejudices that black people and women were inferior.

      What is bad, is sticking to them without even considering other arguments. So is being a total flip-flopper: if you can't see which option is better, you should better refrain from choosing one altogether.

      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.

    No, according to TFA, liberals are faster and more reliable at differentiating between the letter M and the letter W in a timed experiment.

    I think we may safely extrapolate, and say that we expect this to be true for all differentiation between objects,
    I.e. liberals could tell the difference between:

    • a man, a woman, and cop when propositioning someone in the toilets.
    • a deer and the vice-president when out shooting.
    • a WMD and a big fat nothing.
    • having sexual relations, and just mislaying a cigar.

    As for going so far as to say conservatives are slow and stupid. Well, there are many chains to be yanked, but saying that would would be neither fair, nor scientific.

  8. Experimental design by tucuxi · · Score: 5, Informative

    The linked site is scarce on details - the paper itself is more interesting. First, David Amodio (lead researcher) is not obviously flaming. I'm no expert in neuroscience -- but the data looks good, and he has a track record on usage of scans for similar tasks (most of it race-bias related, but that's another subject).

    Here's an interesting part of the experimental design:

    To test the hypothesis that political liberalism (versus conservatism) would be associated with greater conict-related ACC activity, we recorded electroencephalographs from 43 right-handed subjects (63% female) as they performed the Go/No-Go task. Subjects reported their political attitudes condentially on a -5 (extremely liberal) to +5 (extremely conservative) scale. This single-item measure has been found to account for approximately 85% of the statistical variance in presidential voting intentions in American National Election studies between 1972 and 2004 (ref. 8). Among participants in the present study who reported voting in the 2004 presidential election, a more liberal (versus conservative) ideological orientation strongly predicted voting for John Kerry versus George Bush (r(21)= 0.79, P o 0.001).

    I think that there are two ways in which the experiment may be flawed. One is that 43 persons are not enough to extrapolate to the whole US population; and more importantly, no details are given on how they were chosen. If they were chosen among colleagues in an academic setting, where most people (your mileage may vary) are left-wing, you may have problems finding people which self-describe as conservative. These few would be most resistant to changing their viewpoints, I would guess -- since otherwise they may have flipped from exposure to liberal arguments.

    Another way in which I think the study may be flawed is by asking people to self-define their position in the political spectrum -- a one-dimensional political spectrum. What guarantees do you have that participants really are "conservative" or "liberal" (whatever that means to you), and have actually thought about the political issues involved in each "choice" (as if there weren't many, many greys)?. A 2-dimensional political positioning would provide more insight. A short questionnaire where participants actually had to think, instead of "choosing their favorite color" would have been even better.

    This is assuming that the researcher knows what he's doing, and the

    conflict-related ACC activity was indexed by two ERP components. ERPs are scalp-recorded voltage changes reflecting the concerted firing of neurons in response to a psychological event. is actually a good measure of resistance to change or willingness to accomodate it. No details are provided on the exact activity, other than stating that parcicipants were offered the choice of two actions, "Go" and "No-Go".

    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.

    Hating the French and Mexicans is high fashion among the Dixie Republicans and Midwesterners, I doubt they even know why. However they lack the ability to successfully identify the objects of their derision. On a recent trip to Atlanta, GA I was confronted by a few women bemoaning the fact that my family were a bunch of wetbacks here on the dole, and couldn't even be bothered to learn the language. This was wrong on a number of different levels: I am an American Citizen, as is my Daughter. My Girlfriend is Cambodian. We are all legal residents of Austria. My girlfriend had a tourist visa (as we were on holiday). We were speaking German between ourselves and I was trying my best to translate. Despite having lived in Atlanta for a number of years in the past, I was absolutely amazed to be subjected to this sort of hate.

    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.
