Gambling On Bacteria

An anonymous reader writes "When it comes to gambling, many people rely on game theory, a branch of applied mathematics that attempts to measure the choices of others to inform their own decisions. It's used in economics, politics, medicine — and, of course, Las Vegas. But recent findings from a Tel Aviv University researcher suggest that we may put ourselves on the winning side if we look to bacteria instead. According to Prof. Eshel Ben-Jacob of Tel Aviv University's School of Physics and Astronomy, current game theory can't account for bacteria's natural decision-making abilities — it's just too simplistic. Understanding bacteria's reactions to stressful and hazardous conditions may improve decision-making processes in any human arena from everyday life to political elections."

  1. I'm Betting On Bacteria To Win by WrongSizeGlass · · Score: 3, Insightful

    Bacteria has the best chance of surviving whatever we do to the planet, so I'm betting the house on Bacteria to win! Not that it will do me much good when it comes time to collect ... sigh

    If both sides stop acting belligerent, there will be peace.
    However, if Israel stops and the Palestinians don't, there will be mass casualties on Israel's side.
    If the Palestinians stop and Israel doesn't rescind their apartheid policies, the Palestinians will lose what little they have.
    If both sides keep fighting, they will both suffer casualties, but they will not lose everything.

    It's interesting that the Israelis are looking to biological scum for guidance in such matters.

    I'll agree to the basic situation you put forward, but of course the situation is trickier than just two groups on opposite sides. Within each group are a bunch of sub-groups along the spectrum of "let's make peace now" and "we won't stop until they are all dead!" Even if you get most of the groups to agree to a peaceful arrangement, the sub-groups who don't agree can spoil it for everyone by causing trouble, leading to increased tension and eventual breakdown of the peace arrangement. It's very unlikely anytime soon that you will get 100% buy in from all sub-groups within both sides. The best you can hope for is a peace that is strong enough to withstand the inevitable bombardment by the sub-groups who don't join until support for them fades. And, in a region where violence is an everyday fact of life, this is going to be very tough to do.

    Read Phyrrhic victory. Everytime a jew "wins" by brutalizing an opponent which is inferior and powerless in every way, it gives back more in terms of the international goodwill marked "holocaust" than it gains.

    Oh; and the homophobes in Brooklyn yesterday didn't do "the jews" any favors; especially when there was no condemnation from any other "jewish anti-defamation league".

    Just sayin.

    First the Jews came for the Palestinians, and I was quiet, because they wear towels on their head.
    Then the Jews came for the gays, and I said nothing because my best friend is a Jew.
    Then they came for the Jews, and I pretended they didn't have it coming...

  5. Game theory does just fine here by bobdotorg · · Score: 5, Insightful

    IAAGT (I am a game theorist)

    I looked (briefly) but did not find the PNAS article, as I suspect that the medical daily article gets it wrong, and that Prof. Eshel Ben-Jacob doesn't bash game theory tools. The Med Daily reporter probably misinterpreted the Prof.'s comments about groups of bacteria versus groups of people.

    Why don't all the cells go into 'survival mode'? It's not the best for the colony, and there are many real world examples of altruistic behavior towards one's family / colony / species.

    One game theoretical model for this looks through an evolutionary lens: the players are species of bacteria and choose species wide traits. One strategy is 'everybody goes into survival mode', the other strategy is '10% go into survival mode'. Through random mutation, chance, whatever... a species picks its strategy, nature makes its move, and the game goes to the next round.

    Say what?

    Please, compare the number of Israelis (young or old, male or female) that have died at the hands of Palestinians in the last ten years to the number of Palestinian children that died at the hands of Israelis in the last ten months

    In other words, bacteria cooperate.

    In game theory this is a common phenomenon that collective good is boosted when people aren't selfish.
