Statistical Analysis of Terrorism

Harperdog sends in a Miller-McCune story about Aaron Clauset, a researcher whose studies on the statistics and patterns that arise from large numbers of terrorist attacks could help governments better prepare for such conflicts and reduce uncertainty about their frequency and magnitude. Quoting: "After mapping tens of thousands of global terrorism incidents, he and his collaborators have discovered that terrorism can be described by what mathematicians call a power law. ... Using this power law relationship — called 'scale invariance' — the risk of a large attack can be estimated by studying the frequency of small attacks. It’s a calculation that turns the usual thinking about terrorism on its head. 'The conventional viewpoint has been there is "little terrorism" and "big terrorism," and little terrorism doesn't tell you anything about big terrorism,' Clauset explains. 'The power law says that's not true.' Massive acts of violence, like 9/11 or the devastating 1995 bombing of the US embassy in Nairobi, obey the same statistical rules as a small-scale IED attack that kills no one, Clauset's work suggests. 'The power law form gives you a very simple extrapolation rule for statistically connecting the two,' he says."

The driver of the semi truck coming down the road failed to notice the stop sign (or the large "STOP" painted on the road a couple hundred yards before the stop sign) and t-boned them at probably 65 mph. All four people in the pickup were killed. What, exactly, could they have done to "have an arbitrarily high level of control" over their safety in that situation, other than stay off the road?

      The truth is that no matter how careful and skilled a driver you are, when you're on the road your life is in the hands of whatever other drivers happen to be nearby. Generally, they're at least careful enough and skilled enough not to hit you. But sometimes they're not, and there's nothing you can do about that.

    Well, for heading off an anticipated terrorist attack, this is a good result. Good = "attack didn't happen".

    It's probably pretty similar to how the FBI views serial killers and rapists, except in this case they have more leeway with how to deal with suspected perps overseas. At some level, the flow chart kind of goes like "we killed someone(s), and the big boom didn't happen. We probably got the right perps." Or, "we did something, and the expected big boom didn't happen or we (think) we interrupted it", so that's good too.

    While Donald Rumsfeld was being a bit trite and sarchastic (shock!) when he gave his infamous "what we don't know" speech, he probably got it right as far as this area goes.

We (in the polity) don't seem to want to accept probabilities anymore. Our political mobthink currently is that "80% sure" isn't good enough.

    You reply suggests that you misunderstood.
    The power law doesn't suggest where and when an attack happens, so it can't stop a single one from happening. Statistics doesn't predict that just like statistical climate laws won't predict whether it rains tomorrow or not.
    The power law only says how many attacks will probably happen in the next period of time in a certain large area - within a certain degree of freedom.

    And with that infinite wisdom, politicians are able to take appropriate measures. That's the whole point of it.
    Today, politicians scream the loudest so that all voters can hear they take the strongest measures against terrorism of all. That may not be necessary when terrorism can be regarded with the same statistics as traffic deaths, plane crashes, diseases and other causes of death.

    Maybe in the future politicians will say that it is indeed a little pointless to allocate 20% of the annual governmental budget to prevent 3000 terror-deaths, while the same money could save 100,000 in hospitals if it were to be spent on medicine rather than anti-terror measures. (But maybe that's just my wishful thinking).

    Besides, I don't think you can't stop terrorism. You can only motivate people not to be a terrorist in the first place.

    How about we just stop killing and otherwise pissing off brown-skinned people?

    You don't understand what is actually happening. Read Bin Laden's Letter to America. You will see that the actual demand isn't to be "left alone". Bin Laden's first demand is:

    (Q2) As for the second question that we want to answer: What are we calling you to, and what do we want from you?

    (1) The first thing that we are calling you to is Islam.

    Bin Laden demands that we convert to Islam. He follows that up with demands that we ditch the Constitution, implement Islamic Sharia law, and do away with the separation of church and state. Among other things we would have to start killing homosexuals and adulterers, end the charging of interest on bank loans, put an end to drug use, pornography, and alcohol use, amputating the hands of thieves, and many other things. Dressing "immodestly" could get you whipped, which probably means burkas for women. Men would have to grow their beards out, or face a whipping. Crucifixion may be a required punishment for some crimes. Afghanistan under the Taliban was almost ideal to them. If we do not agree to this we can expect that his minions will continue to try to kill us.

    It is not especially significant that Bin Laden issued that demand to the United States, in time every country will have to deal with it. Subduing the United States is just one step along their path, and they understand that it could take 500 years. Many countries have been attacked. Stockholm had a suicide bomber this weekend. (Thankfully it appears that one of the Stockholm terrorist's bombs blew prematurely and he couldn't get about five more planted - otherwise it might have been another Madrid, London 7/7, Bali, or similar bombing.)

    What Do the Terrorists Want? [A Caliphate]

    In nearly all cases, the jihadi terrorists have a patently self-evident ambition: to establish a world dominated by Muslims, Islam, and Islamic law, the Shari'a. Or, again to cite the Daily Telegraph, their "real project is the extension of the Islamic territory across the globe, and the establishment of a worldwide 'caliphate' founded on Shari'a law."

    Terrorists openly declare this goal. The Islamists who assassinated Anwar el-Sadat in 1981 decorated their holding cages with banners proclaiming the "caliphate or death." A biography of one of the most influential Islamist thinkers of recent times and an influence on Osama bin Laden, Abdullah Azzam declares that his life "revolved around a single goal, namely the establishment of Allah's Rule on earth" and restoring the caliphate.

    Bin Laden himself spoke of ensuring that "the pious caliphate will start from Afghanistan." His chief deputy, Ayman al-Zawahiri, also dreamed of re-establishing the caliphate, for then, he wrote, "history would make a new turn, God willing, in the opposite direction against the empire of the United States and the world's Jewish government." Another Al-Qaeda leader, Fazlur Rehman Khalil, publishes a magazine that has declared "Due to the blessings of jihad, America's countdown has begun. It will declare defeat soon," to be followed by the creation of a caliphate.

    Good background here.

    Ignoring them won't make them go away. They have their own goals - nothing we do other than covert to Islam or fight them will dissuade them. Trying to buy them off or deal with them only delays the inevitable. We are in for a long struggle that will be far bloodier for us if we aren't clear about it. Al Qaeda has a f
