Gene Found to Explain Repeated Mistakes 299

Posted by CmdrTaco
from the oh-wait-for-the-joke dept.
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!

    The gene that controls the impulse to tell others what to do, when it isn't necessary to tell them what to do. The 'busybody' gene.

      I think that having this repeated mistake poriblem directly causes you to want to tell others what to do. After all, you do not learn from giving bad advice or instructions either. Explains a lot in politics, religion and management. All these creers where you can be sucessful even after having repeatedly demonstrated bad judgement.

        No, because politicians do what is best for them. They lose nothing by being removed from office, they get to retire and spend their money or write books. No, this gene only affects the voters, the mass of sheep who keep running into the arms of new politicians each election cycle, despite NEVER getting a better deal than they would by simply walking away and firing all the politicians. Anyone who wants the job has already proven their desire for power and for a free ride at the expense of those who are taxed. Yet people still vote for 'em? They still consent to be ruled? Remarkable. This gene must be more effective than we think!!

      My biggest problem with this sort of science is that the general public usually gets everything about it wrong, thanks to bad reporting or poor understanding of science in general. Someone publishes an article stating that morph A of gene X is found more often than one would statistically expect in a number of persons with a specific condition, but when the public gets the results we get headlines screaming "OMFG TEH GHEY GENE FOUND" and that kind of crap, because it makes better press. Yes, there are conditions that can be caused by an aberration in a single gene (albinism, narcolepsy, etc.) but more often than not genes that control complex behaviors require multiple interactions between multiple genes; until proven otherwise you should always understand that publication of a finding like this is indicitave of a contributing factor, not a causal factor, for a given condition.

      Trust me. I do neuroscience for a living. When you're preparing the publication for submission, you always work your hardest to ensure that everything is accurate and properly phrased to be crystal clear about the limitations and drawbacks of the findings, only to have a reporter read nothing more than the abstract and get everything wrong. Don't blame the societal excuses on the scientists. People inclined to take the easy way out don't end up with PhDs, research careers, and articles in Nature.

      We already know that a lot of bad decisions are motivated by other physiological factors - adolescent "testosterone poisioning", PMS, dementia, etc. The fact that cognition has a material basis puts us in a place beyond either "excuses" or simple "suck it up" volitionalism. Each of us is, ultimately and existentially, "responsible" for ourselves. Yet much of our behavior and attitudes are still formed by factors out of our control, and there is no one I know who doesn't have thoughts, behaviors, and emotions which baffle them.

      Knowing the roots of these behaviors gives us a way to short-circuit the negative ones.

      I think the problem is that humans on average are not designed to sit still for hours at little desks and move little symbols on flat bleached trees. A "problem child" may have been a brilliant hunter in an earlier era. I've seen families where one kid is almost an angel and the other from the same parents is a hyper mess. Whips and chains may work in the short term, but create a disturbed personality later in life.

        I rather suspect that if a hyper child spoiled more than one hunt with uncontrollable noise, running about, and blathering, that said child would become dinner. Or a lone nomad at an early age. Like three.

        Be grateful for modern society. Otherwise you'd see hyper kids enjoying such advanced treatment regimes as being tightly swaddled and hung from a hook.

    I think it's interesting that we are so easily convinced that genes control every little detail of our lives. Just because they find a gene that, when modified, affects this trait or that trait; we assume that's all there is to it. It's not. Playing with the genes may be _one_ way to get a certain result. However, it is _not the only_ way to get that same result. Anyone who knows the smallest bit about psychology and sociology know there are many ways to consistantly produce children (and by extension, adults) who repeatedly make mistakes. Heck, even physical injuries to the brain can produce certain behaviors.

    The road called "genes" isn't the only one that can take you to Rome. There are plenty of others. If life was like a golf green, genes would be the contour and speed of the green. Learning, society and environment would be the skill of the golfer, the putter, the wind, etc.

    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.
