Early cost estimates of government projects tend to be optimistic, but does that mean an ambitious project should be scrapped when its price increases?
The Washington Post reports on the political storm surrounding continued funding of the Webb Space Telescope, our planned next-generation instrument:
In 2006, NASA estimated that Webb would cost $2.4 billion and could launch in 2014. In 2008, the price tag rose to $5.1 billion. A congressionally mandated report released last year found that NASA had underestimated costs and mismanaged the project. This summer, NASA said it had already spent $3.5 billion on the project and needed a total of $8.7 billion to launch in 2018.
Against critics who say the gap has been growing and the project should be shut down,
[Edward J.] Weiler [retired head of NASA space sciences] said estimating costs on a project that's never been built before is difficult. "You bid optimistically. That's not just a problem with the James Webb Space Telescope. We see it at NASA all the time; you see it at defense contractors. I would argue -- and I'm not making excuses here -- that [the budget overrun] is a product of the way we do business in America."
Top astronomers said early estimates were never realistic.
"People were used to lowballing," said Garth Illingworth, an astronomer at the University of California at Santa Cruz. "Congress has been part of the game."
The much-acclaimed Hubble Space Telescope, Weiler reminded critics, was also way over budget. And that very point is reflected in the new book by the Nobel Laureate psychologist Daniel Kahneman, Thinking, Fast and Slow, in the chapter dealing with what he and his colleague Amos Tversky called the Planning Fallacy: using best-case scenarios and not reflecting actual costs of similar projects. Poster child: the Scottish Parliament building in Edinburgh, originally budgeted in 1997 at £40 million and finished only in 2004 at a cost of £431 million.
But would we always be better off by following Dr. Kahneman's wise counsel? Shouldn't we look the future squarely in the eye and not fool ourselves about costs? Mark Twain, who virtually bankrupted himself backing an ultimately unworkable typesetter, might have agreed.(Or maybe not; he kept backing esoteric projects like a Polish-Austrian inventor's carpet-pattern machine.) But Dr. Illingworth's remarks suggest there's something else at work, a tacit agreement to keep original estimates deliberately low. Regarding the Scottish Parliament and other architectural megaprojects, the Danish-born program management guru Bent Flyvbjerg believes such enterprises are more often than not Machiavellian charades.Of course that leaves open the question of whether some notorious cases like the Sydney Opera House may turn out to have been worth the deception or self-deception, while others like New Jersey's Xanadu have at least so far been mere money pits.
Scientific instruments are different from monuments; even ardent Scottish nationalists might not claim that the new building will give their country better laws, while the Webb instrument, like the Hubble, might change our view of the universe and our place in it, and yield the surprising economic benefits that expensive pure science (and some military cost overruns) often do. The question is whether the benefit of greater realism in the majority of cases would be offset by the loss of benefits if legislators ruled out all projects that by Kahneman's criteria were likely to produce substantial cost overruns. Sometimes coping with unexpected difficulties produces surprising new solutions, a phenomenon that the economist Albert O. Hirschman has called the Hiding Hand.
Fiscal realism can also have unintended consequences. Cancellation of the Superconducting Super Collider in 1993, it has often been observed, helped drive legions of physicists from big science to even bigger finance, where they developed the computer infrastructure behind the trading that is now the target of Occupy Wall Street. The NASA executive Dr. Charles Beichman wrote tongue-in-cheek to the Financial Times two years ago that it's cheaper to pay scientists and engineers to work on accelerators and telescopes than to turn them loose writing derivatives.
So, on balance I would suggest implementing Dr. Kahneman's procedure, but (in the case of potentially productive investments) looking not just at all the potential additional costs but at the kinds of benefits, including spinoffs, that previous big projects have created. I find it hard to believe that in the context of the whole Federal budget, the Web Space Telescope would not survive that kind of realism.

The Warriors star is the embodiment of basketball’s analytics revolution.
The Golden State Warriors are now some 15 months in to their turn as one of the best teams in basketball history. Last season, they won 67 games, the most in the NBA in eight years, and secured a championship in June against LeBron James and the Cleveland Cavaliers. This season’s Warriors make last season’s Warriors look like a team that hadn’t yet gotten loose. They started the year winning their first 24 games in a row, a record opening, and as of now have won 46 of 50.
Golden State’s brilliance is more than just statistical. The Warriors are a basketball idyll, a paradise of skill and collaboration. Their offense runs on nifty ballhandling, willing passing, and sublime shooting, with their point guard and reigning NBA Most Valuable Player acting as ringleader. A slim 6’3” and 185 pounds, with a bouncy jog and a barely post-pubescent tuft of beard at his chin, Stephen Curry dribbles with the intentional abandon of a card hustler, flings one-handed passes to all sectors of the court, and shoots better than anyone ever has.
It was the apotheosis of the outsiders—two candidates, written off when their campaigns began, recovering from defeat in Iowa to deliver resounding victories in the Granite State.
In a year of outsider success, Tuesday’s New Hampshire primary was the apotheosis of the outsiders. On the Democratic side, Senator Bernie Sanders coasted to a huge victory over Hillary Clinton. And for the Republicans, Donald Trump regained his footing after a letdown in Iowa, winning about a third of the vote and notching a huge victory over the rest of the GOP field.
The results for the rest of the field threatened to remake the race, too. Ohio Governor John Kasich, a moderate technocrat who had seemed to lack traction throughout the campaign, saw his decision to bet all his marbles on New Hampshire pay off, as he came in second. Meanwhile, Senator Marco Rubio had a painful night, falling to an apparent fifth-place finish with the vote mostly tallied—a major stumbling block to his momentum. Chris Christie, whose demolition of Rubio during Saturday night’s debate helped knock Rubio down, didn’t get much of a boost and seemed headed for the exits. Jeb Bush and Ted Cruz battled for the third and fourth spots, while Carly Fiorina and Ben Carson lagged far behind.
After getting shut down late last year, a website that allows free access to paywalled academic papers has sprung back up in a shadowy corner of the Internet.
There’s a battle raging over whether academic research should be free, and it’s overflowing into the dark web.
Most modern scholarly work remains locked behind paywalls, and unless your computer is on the network of a university with an expensive subscription, you have to pay a fee, often around 30 dollars, to access each paper.
Many scholars say this system makes publishers rich—Elsevier, a company that controls access to more than 2,000 journals, has a market capitalization about equal to that of Delta Airlines—but does not benefit the academics that conducted the research, or the public at large. Others worry that free academic journals would have a hard time upholding the rigorous standards and peer reviews that the most prestigious paid journals are famous for.
The number of American teens who excel at advanced math has surged. Why?
On a sultry evening last July, a tall, soft-spoken 17-year-old named David Stoner and nearly 600 other math whizzes from all over the world sat huddled in small groups around wicker bistro tables, talking in low voices and obsessively refreshing the browsers on their laptops. The air in the cavernous lobby of the Lotus Hotel Pang Suan Kaew in Chiang Mai, Thailand, was humid, recalls Stoner, whose light South Carolina accent warms his carefully chosen words. The tension in the room made it seem especially heavy, like the atmosphere at a high-stakes poker tournament.
Stoner and five teammates were representing the United States in the 56th International Mathematical Olympiad. They figured they’d done pretty well over the two days of competition. God knows, they’d trained hard. Stoner, like his teammates, had endured a grueling regime for more than a year—practicing tricky problems over breakfast before school and taking on more problems late into the evening after he completed the homework for his college-level math classes. Sometimes, he sketched out proofs on the large dry-erase board his dad had installed in his bedroom. Most nights, he put himself to sleep reading books like New Problems in Euclidean Geometry and An Introduction to Diophantine Equations.
He’s made the once-impossible seem possible—and now all bets are off.
CONCORD, New Hampshire—“Thank you, New Hampshire!” a somber but clearly gratified Bernie Sanders said to a crowd of thrilled supporters in a high-school gymnasium. The 74-year-old democratic socialist from Vermont had just resoundingly won the New Hampshire Democratic primary, dealing an astonishing blow to the Hillary Clinton juggernaut, casting the race into turmoil, and dramatically highlighting the dissatisfaction of the party base with its establishment.
Sanders’s win, he said, had sent a message to the country: “That the government of our great country belongs to all of the people, and not just a handful of wealthy campaign contributors and their super PACs!” The contest, he noted, had inspired record turnout, powered by a force that he implied would make him a better general-election candidate than his rival—“the energy and the excitement that the Democratic Party will need to succeed in November.”
Sanders’s youth movement is powered by the energy of the new campus left. What does it believe?
RINDGE, New Hampshire—Twenty-three minutes into his typically rambling, hourlong stump speech in the arena here, at a private liberal-arts college on the Massachusetts border—after he had decried the Koch brothers and the prescription-drug companies, after he had accused Wall Street of bribing its way to deregulation, after he had called out the corporate media and the political establishment—Bernie Sanders turned to the bleachers behind him, which were filled with college students waving blue signs and chanting his name.
A sly, unusual smile crossed his face. “I feel like a rock-n-roll star!” he exclaimed, taking off his jacket and tossing it to a startled youth behind him. He pantomimed tearing off his sweater, too, prompting a fresh chant of “Ber-nie! Ber-nie!” Then he grinned sheepishly. “All right, nothing else is coming off,” he said, and continued to the next topic—the sins of Walmart.
For decades the Man of Steel has failed to find his groove, thanks to a continual misunderstanding of his strengths.
Superman should be invincible. Since his car-smashing debut in 1938, he’s starred in at least one regular monthly comic, three blockbuster films, and four television shows. His crest is recognized across the globe, his supporting cast is legendary, and anybody even vaguely familiar with comics can recount the broad strokes of his origin. (The writer Grant Morrison and the artist Frank Quitely accomplished it in eight words and four panels: “Doomed Planet. Desperate Scientists. Last Hope. Kindly Couple.”) He’s the first of the superheroes, a genre that’s grown into a modern mass-media juggernaut.
And yet, for a character who gains his power from the light of the sun, Superman is curiously eclipsed by other heroes. According to numbers provided by Diamond Distributors, the long-running Superman comic sold only 55,000 copies a month in 2015, down from around 70,000 in 2010—a mediocre showing even for the famously anemic comic-book market. That’s significantly less than his colleague Batman, who last year moved issues at a comparatively brisk 150,000 a month. Mass media hasn’t been much kinder: The longest-running Superman television show, 2001’s Smallville, kept him out of his iconic suit for a decade. Superman Returns recouped its budget at the box office, but proved mostly forgettable.2013’s Man of Steel drew sharp criticism from critics and audiences alike for its bleak tone and rampaging finale. Trailers for the sequel, Batman v Superman: Dawn of Justice, have shifted the focus (and top billing) to the Dark Knight. Worst of all, conventional wisdom puts the blame on Superman himself. He’s boring, people say; he’s unrelatable, nothing like the Marvel characters dominating the sales charts and the box office. More than anything, he seems embarrassing. Look at him. Truth? Justice? He wears his underwear on the outside.
Black poverty is fundamentally distinct from white poverty—and so cannot be addressed without grappling with racism.
There have been a number of useful entries in the weeks since Senator Bernie Sanders declared himself against reparations. Perhaps the most clarifying comes from Cedric Johnson in a piece entitled, “An Open Letter To Ta-Nehisi Coates And The Liberals Who Love Him.” Johnson’s essay offers those of us interested in the problem of white supremacy and the question of economic class the chance to tease out how, and where, these two problems intersect. In Johnson’s rendition, racism, in and of itself, holds limited explanatory power when looking at the socio-economic problems which beset African Americans. “We continue to reach for old modes of analysis in the face of a changed world,” writes Johnson. “One where blackness is still derogated but anti-black racism is not the principal determinant of material conditions and economic mobility for many African Americans.”
Most people in the U.S. believe their country is going to hell. But they’re wrong. What a three-year journey by single-engine plane reveals about reinvention and renewal.
When news broke late last year of a mass shooting in San Bernardino, California, most people in the rest of the country, and even the state, probably had to search a map to figure out where the city was. I knew exactly, having grown up in the next-door town of Redlands (where the two killers lived) and having, by chance, spent a long period earlier in the year meeting and interviewing people in the unglamorous “Inland Empire” of Southern California as part of an ongoing project of reporting across America.
Some of what my wife, Deb, and I heard in San Bernardino before the shootings closely matched the picture that the nonstop news coverage presented afterward: San Bernardino as a poor, troubled town that sadly managed to combine nearly every destructive economic, political, and social trend of the country as a whole. San Bernardino went into bankruptcy in 2012 and was only beginning to emerge at the time of the shootings. Crime is high, household income is low, the downtown is nearly abandoned in the daytime and dangerous at night, and unemployment and welfare rates are persistently the worst in the state.
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.
