Do the emotional centers of the brain guide our politics?

—  

People who hold specific political points of view like to think their positions are based on serious analysis.

They view their given ideologies as careful conclusions reached through assessing the world around them and examining how things work. Thus, liberals and conservatives both manage to claim the intellectual and ethical high ground.

But what if this is a bunch of hogwash? What if political viewpoints are nothing more than the result of brain patterns, neuron pathways and perhaps a little genetics mixed in? What if our political points of view aren’t shaped by thoughts, but rather, by biology?

That’s an intriguing notion coming out of some recent brain research. I stumbled upon it the other day on the Discovery News website, which cited new research where analysts said they had spotted key differences between the way the brains of liberals and conservatives worked.

Technically, the study was looking at how brains process risk when it comes to gambling. Interestingly, liberals and conservatives were both willing to take similar risks in gambling games, but in the two groups, different areas of the brains were used to process the information before them.

Specifically, conservatives tended to use areas of the brain linked to rewards, fear and risky behavior, while liberals used parts of the brain tied to emotion and what some experts believe is a sense of what others may be thinking. Intuition may be a good term for it.

Of course, this study presents something of a chicken-vs-egg argument. Did the political views of the subjects create the brain activity? Or did the brain activity generate the political views?

Or is something else going on here?

Personally, I have long observed that political ideology has much more to do with fear than reason. Spend much time listing to people with strident political views and you can easily conclude they are terrified of something.

    The violation of privacy argument by liberal detractors of the Supreme Court's decision in the Hobby Lobby-Obamacare case doesn't hold water when you consider the current collection and use of the personal details of your medical preferences.

    'Independence Day' is now an ironic celebration in a country where the president promotes government dependence over actual freedom, and where bumper-sticker slogans have replaced actual, independent thought.

    Uber gives urban passengers an enticing alternative. Rides on-demand arrive faster than taxis, are cheaper and cleaner, and get rated by customers. Rather than hail innovation, government enablers are helping the heavily regulated taxicab industry freeze out the upstart.

  • taylor.armerding.jpg IRS spins email yarn as Obama slips past another scandal

    Forget everything you've heard about email. All digital trace of a former IRS official's email over the 25 months the agency harassed conservative groups has mysteriously, improbably vanished. Gone, too, is the White House's accountability as President Obama slips from another scandal.

  • taylor.armerding.jpg Obama: Don't listen to those who knew Bergdahl best

    The Obama administration chides anyone who suggests that Army Sgt. Bowe Bergdahl - the POW traded for a dream team of Taliban terrorists - might be something less than a hero. The White House wants us to stop jumping to conclusions - unless, of course, we're jumping to the right conclusions.

    Weighing the "true cost" of coal-based energy is politically convenient. In a "true cost" world, coal may be more expensive but alternate energies aren't affordable, either; you don't get a tax break on your mortgage; and the feds don't protect the United Auto Workers from Chrysler's bankruptcy.

    Poor care and long wait times at the Veterans Administration are little surprise for an organization with such an entrenched bureaucracy. It's almost predictable as the Obama administration's mock surprise and non-response.

    Terrorists were supposed to disappear and tensions would dissolve between the United States and other countries when President Barack Obama took office. But prize-winning promises don't hold up to real-life Chinese hackers, attacks on U.S. diplomats and Russian land grabs.
