I know that Paul Krugman was not really serious when he linked this study naming him the most accurate prognosticator in America. Nonetheless, it's getting some play around the internet, and a warm reception from people who don't seem to know any better, so it's worth pointing out why this sort of thing is so dreadful. I mean, I'm sure it was a very fine senior project for the Hamilton College students who produced it, but the results tell us nothing at all about the state of prognostication in this country.
Krugman quotes this segment from the Hamilton College press release:
Now, a class at Hamilton College led by public policy professor P. Gary Wyckoff has analyzed the predictions of 26 prognosticators between September 2007 and December 2008. Their findings? Anyone can make as accurate a prediction as most of them if just by flipping a coin.
The students found that only nine of the prognosticators they studied could predict more accurately than a coin flip. Two were significantly less accurate, and the remaining 14 were not statistically any better or worse than a coin flip.
The top prognosticators - led by New York Times columnist Paul Krugman - scored above five points and were labeled "Good," while those scoring between zero and five were "Bad." Anyone scoring less than zero (which was possible because prognosticators lost points for inaccurate predictions) were put into "The Ugly" category. Syndicated columnist Cal Thomas came up short and scored the lowest of the 26.
I myself read Paul Krugman more often than Cal Thomas, so perhaps I should take this as evidence of my perspicacity . . . but no. This is nonsense. The study runs for a little over a year, between September 2007 and 2008. They didn't even look at all of the statements made by the prognosticators, but at a "representative sample", presumably because they couldn't handle the volume that would be required to analyze all of it. Some of the prognosticators made too few testable predictions to generate good results, and the riskiness of the prediction varied--someone who predicted that Obama was going to win the election in October 2008 seems to have gotten the same "score" for that flip as someone who predicted that Obama would do so in September 2007. The number of predictions varied between commentators, making comparison even more difficult.
Against this background, it makes no sense to say--as the students and the press release do--that this study shows that "a number of individuals in our sample, including Paul Krugman, Maureen Dowd, Ed Rendell, Chuck Schumer, Nancy Pelosi, and Kathleen Parker were better than a coin flip (sometimes, substantially so.)" One of the commonest fallacies you see among beginning students of probability is the belief that if a coin has a 50% chance of turning up heads, then anyone who flips a coin multiple times should end up getting half heads, and half tails.
This is not true--especially when you have a small number of "flips", as most of the prognosticators did. (It's not surprising that George Will, who made the greatest number of predictions, was statistically very close to zero.) Rather, if you get a bunch of people to flip coins a bunch of times, you'll get a distribution. Most of the results will cluster close to 50/50 (as was true in this case), but you'll get outliers.
This is often pointed out in the case of mutual fund managers, as John Bogle does using this graph:
And indeed, my finance profs taught me that the top mutual funds in a given year are not any more likely to show up as next year's top funds. Indeed, they may be less likely to do well the next year. Why? Because funds have strategies, which do better or worse depending on market conditions. The funds that do well in a given year are probably the funds that were especially well positioned to show outsized fluctuations in response to whatever changed that year--but that also means that they're especially likely to do lose money when those conditions change. Because the fluctuations are a random walk, they do not vindicate the fund manager's strategy or perspicacity--but they may seem to, temporarily.
Which may cast some light on why liberal pundits did especially well in this test. If you were the sort of person who is systematically biased towards predicting a bad end for Republicans, and a rosy future for Democrats, then election year 2008 was going to make you look like a genius. If you were the sort of person who takes a generally dim view of anything Democrats get up to, then your pessimism was probably going to hit more often than it missed.
It would be interesting to go back and look at the same group in the year running up to 2010. But even then, it would tell us very little. To do any sort of a true test, we'd have to get a bunch of these prognosticators to all make predictions about the same binary events, over a lengthy period of time, and then see how they fared over a multi-year period. I suspect that they'd end up looking a lot like mutual fund managers: little variation that could be distinguished from random variance.
Once you take into account their fees, mutual fund managers, as a group, underperform the market. And I suspect you'd see the same thing with pundits: as a group, they'd slightly underperform a random coin flip. People like Lindsay Graham cannot go on Meet the Press and say "Yup, we're going to lose on November 2nd" even when it is completely obvious that this is what will happen; they need to present an optimistic bias for their base. Over time, that optimistic bias about no-hope causes will cause a slight negative drag on the predictive power of their statements.
Does that undermine the credibility of pundits? I don't think that predictions are the fundamental purpose of punditry (though I do encourage people to make them as a way of raising the stakes on the truth claims they make, and in order to give us a benchmark against which to analyze our reasoning). Pundits offer predictions, yes, but more importantly, they offer you facts, context, and analysis. Their really important work is to help you make your own wrong predictions about the world.
Forget credit hours—in a quest to cut costs, universities are simply asking students to prove their mastery of a subject.
MANCHESTER, Mich.—Had Daniella Kippnick followed in the footsteps of the hundreds of millions of students who have earned university degrees in the past millennium, she might be slumping in a lecture hall somewhere while a professor droned. But Kippnick has no course lectures. She has no courses to attend at all. No classroom, no college quad, no grades. Her university has no deadlines or tenure-track professors.
Instead, Kippnick makes her way through different subject matters on the way to a bachelor’s in accounting. When she feels she’s mastered a certain subject, she takes a test at home, where a proctor watches her from afar by monitoring her computer and watching her over a video feed. If she proves she’s competent—by getting the equivalent of a B—she passes and moves on to the next subject.
The Wall Street Journal’s eyebrow-raising story of how the presidential candidate and her husband accepted cash from UBS without any regard for the appearance of impropriety that it created.
The Swiss bank UBS is one of the biggest, most powerful financial institutions in the world. As secretary of state, Hillary Clinton intervened to help it out with the IRS. And after that, the Swiss bank paid Bill Clinton $1.5 million for speaking gigs. TheWall Street Journal reported all that and more Thursday in an article that highlights huge conflicts of interest that the Clintons have created in the recent past.
The piece begins by detailing how Clinton helped the global bank.
“A few weeks after Hillary Clinton was sworn in as secretary of state in early 2009, she was summoned to Geneva by her Swiss counterpart to discuss an urgent matter. The Internal Revenue Service was suing UBS AG to get the identities of Americans with secret accounts,” the newspaper reports. “If the case proceeded, Switzerland’s largest bank would face an impossible choice: Violate Swiss secrecy laws by handing over the names, or refuse and face criminal charges in U.S. federal court. Within months, Mrs. Clinton announced a tentative legal settlement—an unusual intervention by the top U.S. diplomat. UBS ultimately turned over information on 4,450 accounts, a fraction of the 52,000 sought by the IRS.”
Even when a dentist kills an adored lion, and everyone is furious, there’s loftier righteousness to be had.
Now is the point in the story of Cecil the lion—amid non-stop news coverage and passionate social-media advocacy—when people get tired of hearing about Cecil the lion. Even if they hesitate to say it.
But Cecil fatigue is only going to get worse. On Friday morning, Zimbabwe’s environment minister, Oppah Muchinguri, called for the extradition of the man who killed him, the Minnesota dentist Walter Palmer. Muchinguri would like Palmer to be “held accountable for his illegal action”—paying a reported $50,000 to kill Cecil with an arrow after luring him away from protected land. And she’s far from alone in demanding accountability. This week, the Internet has served as a bastion of judgment and vigilante justice—just like usual, except that this was a perfect storm directed at a single person. It might be called an outrage singularity.
Bernie Sanders and Jeb Bush look abroad for inspiration, heralding the end of American exceptionalism.
This election cycle, two candidates have dared to touch a third rail in American politics.
Not Social Security reform. Not Medicare. Not ethanol subsidies. The shibboleth that politicians are suddenly willing to discuss is the idea that America might have something to learn from other countries.
The most notable example is Bernie Sanders, who renewed his praise for Western Europe in a recent interview with Ezra Klein. “Where is the UK? Where is France? Germany is the economic powerhouse in Europe,” Sanders said. “They provide health care to all of their people, they provide free college education to their kids.”
On ABC’s This Week in May, George Stephanopoulos asked Sanders about this sort of rhetoric. “I can hear the Republican attack ad right now: ‘He wants American to look more like Scandinavia,’” the host said. Sanders didn’t flinch:
The Islamic State is no mere collection of psychopaths. It is a religious group with carefully considered beliefs, among them that it is a key agent of the coming apocalypse. Here’s what that means for its strategy—and for how to stop it.
What is the Islamic State?
Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.
A hawkish senator doesn't apply the lessons of Iraq
Earlier this week, Senator Lindsey Graham, a hawkish Republican from South Carolina, used a Senate Armed Services Committee hearing to stage a theatrical display of his disdain for the Obama administration’s nuclear deal with Iran.
The most telling part of his time in the spotlight came when he pressed Defense Secretary Ashton Carter to declare who would win if the United States and Iran fought a war:
Here’s a transcript of the relevant part:
Graham: Could we win a war with Iran? Who wins the war between us and Iran? Who wins? Do you have any doubt who wins?
Carter: No. The United States.
Graham: We. Win.
Little more than a decade ago, when Senator Graham urged the invasion of Iraq, he may well have asked a general, “Could we win a war against Saddam Hussein? Who wins?” The answer would’ve been the same: “The United States.” And the U.S. did rout Hussein’s army. It drove the dictator into a hole, and he was executed by the government that the United States installed. And yet, the fact that the Iraqi government of 2002 lost the Iraq War didn’t turn out to mean that the U.S. won it. It incurred trillions in costs; thousands of dead Americans; thousands more with missing limbs and post-traumatic stress disorder and years of deployments away from spouses and children; and in the end, a broken Iraq with large swaths of its territory controlled by ISIS, a force the Iraqis cannot seem to defeat. That’s what happened last time a Lindsey Graham-backed war was waged.
The IOC’s selection of Beijing as the host of its 2022 games is met with a lukewarm response.
When the International Olympic Committee selected Beijing on Friday as the host for the 2022 Winter Olympic Games, the Chinese capital became the first city to have hosted both the Summer and Winter games. This, most likely, isn’t coincidental: Beijing’s hosting of the Summer games in 2008 was generally considered a success, and Almaty, the Kazakh city whose bid placed second, lacks comparable experience.
A closer examination of Beijing’s 2022 bid, though, reveals the selection is far more peculiar than it seems at first glance. One reason: It barely snows in Beijing. China’s northern plain is extremely dry, and what precipitation that falls in the capital tends to occur during the summer. Beijing’s Olympic planners have assured the IOC this won’t be a problem—the country will simply use artificial snow to accommodate events, such as skiing, that require it.
Who can devise the most convoluted way to wipe out the Islamic State?
Everyone with a stake in Middle Eastern geopolitics publicly declares that ISIS must be defeated. Yet opinions range widely on how this should be achieved.
Saudi Arabia, for example, believes ISIS cannot be defeated unless Syrian President Bashar al-Assad is removed from power. Turkey has just convinced NATO nations that the war against ISIS can only be won if Turkey’s traditional Kurdish opponents are neutralized first. Israel sees only one way to defeat ISIS: destroy Iran’s nuclear program and clip its wings regionally.
So what explains these apparently contradictory aims? The cynical view would be that all these parties are less interested in defeating ISIS than in achieving their own regional goals, and that they’re only pretending to be concerned about wiping out the group. Clearly, however, there is no place for cynicism in Middle Eastern politics. Everyone involved in the region is known to be sincere, albeit in radically different ways.
Jim Gilmore joins the race, and the Republican field jockeys for spots in the August 6 debate in Cleveland.
After decades as the butt of countless jokes, it’s Cleveland’s turn to laugh: Seldom have so many powerful people been so desperate to get to the Forest City. There’s one week until the Republican Party’s first primary debate of the cycle on August 6, and now there’s a mad dash to get into the top 10 and qualify for the main event.
With former Virginia Governor Jim Gilmore filing papers to run for president on July 29, there are now 17 “major” candidates vying for the GOP nomination, though that’s an awfully imprecise descriptor. It takes in candidates with lengthy experience and a good chance at the White House, like Scott Walker and Jeb Bush; at least one person who is polling well but is manifestly unserious, namely Donald Trump; and people with long experience but no chance at the White House, like Gilmore. Yet it also excludes other people with long experience but no chance at the White House, such as former IRS Commissioner Mark Everson.
Donald Trump has gained political traction by demagoguing on an issue more responsible leaders have neglected.
Why has the Donald Trump candidacy—which so many professionals and pundits at first dismissed as a joke—flared this summer? In the first week of July, 15 percent of Republicans supported Trump for president in a YouGov poll. By the third week, that support had almost doubled, to 28 percent—with another 10 percent listing him as their second choice.
Something happened in July to send Trump’s numbers soaring. That something may have been the murder of Kathryn Steinle.
On July 5, the 32-year-old Steinle posed with her father for a photograph on a San Francisco pier at 6:30 on a Wednesday evening. Suddenly there was a pop. Steinle crumpled. She died in hospital two hours later.
The stunningly random killing left behind a devastated family—and a confessed killer: Juan Francisco Lopez-Sanchez, an illegal immigrant from Mexico who had been convicted of seven previous felonies and five times been ordered deported from the United States.
