Gene Found to Explain Repeated Mistakes

palegray.net writes "A December 6th article in Nature explores the relationship between a specific gene and those of us prone to repeatedly making the same mistakes. From the article: "Drug addicts, alcoholics and compulsive gamblers are known to be more likely than other people to have this genetic mutation ..." The gene results in the development of fewer D2 receptors in the brain, a condition which the study has shown leads to a lessened ability to learn from experience." So no complaining about dupes and typos: it's genetic!

    I know a recovering alcoholic pretty well, and one of her pronounced traits is repeatedly doing the same things that she knows she shouldnt. Keep in mind that the phrase "Insanity is doing the same action over and over again and expecting a different result" comes from AA.

    Oddly enough, it only became really pronounced AFTER she stopped drinking - gene activation?

    Isn't addiction the result of the brain learning too well that getting a certain stimulus triggers the pleasure/reward sensation? It's only a "mistake" when the stimulus turns out to be a false positive. The same "addicted" reaction to a drug that short-circuits the reward sensation might cause a person to acquire and maintain very good habits for needed nutrients or acquiring resources. It's a tradeoff between locking in behaviors that consistently produce rewards and the risk that you are locking in slowly self-destructive behaviors that only seemed to be a reward. A person who can break addictions easily may also tend to randomly stop doing useful, rewarding things.

    You trust your politicians? Of course not. Quite the contrary. For instance here in Sweden there have recently been several scandals with politicians not paying their taxes. We expect them to be selfish, and adapt our systems in such ways that their selfishness will work in our interest.

    For example, here in Sweden the members of the government, the ministers, have no right to give orders to authorities. Ministers decide about policy, and are expressly forbidden from meddling in the day-to-day matters of the authorities. That's to limit the influence of the power-hungry. The only exception is when an authority asks for a policy decision, and also some exceptional authorities such as the one that manages embassies and foreign affairs.

    This arrangement complicated matters a lot when a Swede was released from Guantanamo. The US demanded guarantees from the Swedish government that he would be supervised. Since the government is expressly forbidden from giving any such orders they couldn't give any such guarantees.

    It would make more sense for you Americans to simply expect your politicians to be selfish like everybody, and not despise them for that, and instead despise your system if it doesn't provide suitable checks and balances. Which I think it doesn't.
