SXSW: Nate Silver Discusses Data Bias, the Strangeness of Fame

Nerval's Lobster writes "Nate Silver feels a little odd about his fame. That's not to say that he hasn't worked to get to his enviable position. Thanks to his savvy with predictive models, and the huge readership platform provided by The New York Times hosting his FiveThirtyEight blog, he managed to forecast the most recent presidential election results in all 50 states. His accuracy transformed him into a rare breed: a statistician with a household name. But onstage at this year's SXSW conference, Silver termed his fame 'strange' and 'out of proportion,' and described his model as little more than averaging the state and national polls, spiced a bit with his algorithms. "It bothered me that this was such a big deal," he told the audience. In politics, he added, most of the statistical analysis being conducted simply isn't good, which lets someone like him stand out; same as in baseball, where he made his start in predictive modeling. In fields with better analytics, the competition for someone like him would be much fiercer. He also talked about, despite a flood of data (and the tools to analyze it) in the modern world, we still face huge problems when it comes to actually understanding and using that data. 'You have a gap between what we think we know and what we really know,' he said. 'We tend to be oversensitive to random fluctuations in the data and mistake the fluctuations for real relationships.'"

    I think Silver stands out because unlike too many modern American politicians, he is interested in the facts, and not what bullshit he can use the data to support.

    So it's not so much that he's done a fantastic job figuring all this out, it's just that he's fucking honest about the results unlike a certain perpetually-deluded political party I'm sick of naming.

      Both sides are not equally wrong, but that doesn't mean both sides are right. The Republicans are wrong 99% of the time. The Democrats are wrong 95% of the time. Why can't we field a candidate who's right even half the time?

      If you vote for the party that's right most often, you're still voting for someone who is almost always wrong.

      You can't deadlock them, you can only deadlock us. The Democrats and Republicans have a lot more in common than they have differences. The rich people who control the Democrats have much more in common with the rich people that control the Republicans than either have with any of us. The worst thing that could happen to the Democratic party is for the Greens to win some major elections.

      If the Democrats are 95% wrong, and the Republicans are 99% wrong, that means that 90% of the time they are completely unopposed in doing the wrong thing. If you vote for either Democrats or Republicans, that's what you're voting for.

      Arguably, it isn't really politicians who he differs from most meaningfully. Sure, there are a lot of politicians living in absurd contrafactual fantasy worlds; but that is(unfortunately) mostly a product of the fact that they are acting as representatives of people who do exactly the same thing... Pandering is a nonfactual enterprise in the sense that it may involve telling people the most insane lies, if that is what they want from you; but it is an eminently empirical exercise in the sense that you must constantly strive to better understand what people want to hear, so that you can better pander to them.

      Where Silver, and his data-driven compatriots, really differ from the traditional is with the 'pundit' class. Pundits are selected pretty much entirely for their ability to tell emotionally compelling stories, with minimal reference to data, and provide marketable column inches and cable news minutes. The better ones, to their credit, are masterful in engaging audience emotions, weaving stories, and other affectively gripping flimflam. However, they tend to be somewhere between extraordinarily weak and overtly hostile to the idea that 'data' rather than 'feelings' can actually provide excellent information about the world, particularly if you use this crazy 'math' stuff that the nerds are always going on about.

      Pundits make good TV(and, very conveniently, can offer viewers everything from lowbrow talk radio shouting matches to middlebrow 'public intellectual' posturing with little more than a change in tone and presence or absence of a thesaurus, unlike stat-heads who pretty fundamentally lean on nontrival math); but the kind of suck compared to statistical models.

Warrantless wiretapping, eternal copyright, the war on drug users, the ever increasing militarization of the police, the for-profit prison industry, and a DOJ that cares more about Aaron Swartz than about John Corzine, etc, etc,. The Democrats and Republicans agree on most of the most harmful policies that afflict this country. And when they pretend to disagree (e.g. Rand Paul on domestic drone strikes), it's all for show.

      The cause of the debt in the US, is that the GOP believes in spontaneously generating wealth. They book the projected increases in revenue as being real when balancing the budget, but fail to make any adjustments when that turns out to not be the case.

      Ultimately, the Democrats at least understand that you need real revenue in order to balance the budget and you have to actually make real cuts to the DoD which alone could more than finance Obamacre with the waste in war spending without having to cut back on things that actually matter.

      Mod up! This is exactly what happened last November. It wasn't the politicians who Nate revealed had no clothes, it was the pundits. While stories abound about Romney's supreme overconfidence, I think one could tell from the Republican rank and file that they knew months before the election that Obama was going to win a second term and there was little likelihood that they could gain a Senate majority.

      But the pundits, now that was a group that was utterly stripped of any illusion of wisdom. They were proven to be absolute fools, little more than shouting ignoramuses. I hope that Silver and the other statisticians working on electoral prediction continue to hound this overpaid talking heads to extinction. In no small part, politics is as bad as it is because of the pundits.

      Just to pile on, when you say "both sides do it," you are implicitly refusing to deal with the actual topic at hand, which is for example "budget" or "national security," or whatever.

      So when you do that, you are basically throwing up your hands and saying "who can know such things?"

I can't recall such a long sequence of useless posts on slashdot, and that's really saying something!

      Yes, Nate Silver called out the Pundits. Even I could have done that. He went further, and pointed out a significant discrepancy between the national and state polls. He made a gut call and pointed the finger of bias at the national polls, and based his model mostly on the state polls. That he was right isn't what impressed me. Most of the Democratic pundits were already screaming about national poll bias. What impressed me was that he had the guts to point that finger right at the most respected name in polling, Gallup. He totally put his reputation and career on the line. He explained in clear detail why Gallup was wrong, and by how much. He predicted how much Gallup would be wrong, and explained how Gallup would spin their errors as being due to Hurricane Sandy, all before Gallup's final errors. Faced with this onslaught from Nate, Gallup, the most experienced polling organization in the world, following the script Nate predicted point by point. Gallup is about as useful as used toilet paper. They're frankly stupid morons. So, thanks for letting us know, Nate!

      The thing is you can have mountains of data (which we do). The problem is asking the right questions.

      The problem is that those in power dont want to ask the right questions because it will force their hand. e.g., we have mountains of data that show that Cannabis is less harmful than most over the counter drugs. Certainly less harmful than alcohol. So we 75,000 of us get together and ask the President a question. "Why can't we regulate Cannabis like alcohol?"

      His response amounted to "Cannabis is a dangerous drug", and he never mentioned alcohol once. He didn't even bother dismissing the question, he failed to acknowledge its existence.

      Why would he do that? It's obvious, if he actually considered the question, he would have been unable to come up with an answer that would be consistent with our current policy. He knows that, and he doesn't care that the policy is demonstrably harmful.

      That, my friends, is the face of evil.

    Because "right" is for better or worse often a matter of opinion. There is no single objectively right answer for many questions. Think abortion or gun control. Lots of opinions on both sides but there is never going to be a single "right" answer. At best there might be a consensus but probably never a unanimous one.
