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 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.
The Republican frontrunner has surged in the polls by taking a tough stance on immigration—and if critics want to stop him, that’s what they need to attack.
A new round of attack ads are heading Donald Trump’s way, some from John Kasich’s campaign and the super PAC backing him, and more in the future from an LLC created specifically to produce anti-Trump messages.
New Day for America’s 47-second ad splices together some of the Republican front-runner’s most awkward video moments: his suggestion he might date his daughter, his claim of “a great relationship with the blacks.” The Kasich campaign’s ad turns Martin Niemöller’s famous words “nobody left to speak for me” into a warning from one of John McCain’s fellow Hanoi Hilton POWs that a Trump presidency is a threat to freedom.* John Kasich’s Twitter account has fired direct personal challenges to the famously thin-skinned mogul.
Two economists share what they've learned from tracking airfare's seemingly inscrutable fluctuations.
Why are so many kids with bright prospects killing themselves in Palo Alto?
The air shrieks, and life stops. First, from far away, comes a high whine like angry insects swarming, and then a trampling, like a herd moving through. The kids on their bikes who pass by the Caltrain crossing are eager to get home from school, but they know the drill. Brake. Wait for the train to pass. Five cars, double-decker, tearing past at 50 miles an hour. Too fast to see the faces of the Silicon Valley commuters on board, only a long silver thing with black teeth. A Caltrain coming into a station slows, invites you in. But a Caltrain at a crossing registers more like an ambulance, warning you fiercely out of its way.
The kids wait until the passing train forces a gust you can feel on your skin. The alarms ring and the red lights flash for a few seconds more, just in case. Then the gate lifts up, signaling that it’s safe to cross. All at once life revives: a rush of bikes, skateboards, helmets, backpacks, basketball shorts, boisterous conversation. “Ew, how old is that gum?” “The quiz is next week, dipshit.” On the road, a minivan makes a left a little too fast—nothing ominous, just a mom late for pickup. The air is again still, like it usually is in spring in Palo Alto. A woodpecker does its work nearby. A bee goes in search of jasmine, stinging no one.
America loves its freeways. After the 1956 Federal Highway Bill created the pathway for a41,000 mile interstate highway system, states and cities jockeyed for the funding to build ever-more extensive networks of pavement that could carry Americans quickly between cities. Sometimes, they built these highways right in the middle of cities, displacing communities and razing old buildings and homes.
“This was a program which the twenty-first century will almost certainly judge to have had more influence on the shape and development of American cities, the distribution of population within metropolitan areas and across the nation as a whole, the location of industry and various kinds of employment opportunities,”Daniel Moynihan wrote in 1970 about the federal program that built these thousands of miles of highways.
In the name of emotional well-being, college students are increasingly demanding protection from words and ideas they don’t like. Here’s why that’s disastrous for education—and mental health.
Something strange is happening at America’s colleges and universities. A movement is arising, undirected and driven largely by students, to scrub campuses clean of words, ideas, and subjects that might cause discomfort or give offense. Last December, Jeannie Suk wrote in an online article for The New Yorker about law students asking her fellow professors at Harvard not to teach rape law—or, in one case, even use the word violate (as in “that violates the law”) lest it cause students distress. In February, Laura Kipnis, a professor at Northwestern University, wrote an essay in The Chronicle of Higher Education describing a new campus politics of sexual paranoia—and was then subjected to a long investigation after students who were offended by the article and by a tweet she’d sent filed Title IX complaints against her. In June, a professor protecting himself with a pseudonym wrote an essay for Vox describing how gingerly he now has to teach. “I’m a Liberal Professor, and My Liberal Students Terrify Me,” the headline said. A number of popular comedians, including Chris Rock, have stopped performing on college campuses (see Caitlin Flanagan’s article in this month’s issue). Jerry Seinfeld and Bill Maher have publicly condemned the oversensitivity of college students, saying too many of them can’t take a joke.
An entire industry has been built on the premise that creating gourmet meals at home is simple and effortless. But it isn’t true.
I write about food for a living. Because of this, I spend more time than the average American surrounded by cooking advice and recipes. I’m also a mother, which means more often than not, when I return from work 15 minutes before bedtime, I end up feeding my 1-year-old son squares of peanut-butter toast because there was nothing in the fridge capable of being transformed into a wholesome, homemade toddler meal in a matter of minutes. Every day, when I head to my office after a nourishing breakfast of smashed blueberries or oatmeal I found stuck to the pan, and open a glossy new cookbook, check my RSS feed, or page through a stack of magazines, I’m confronted by an impenetrable wall of unimaginable cooking projects, just sitting there pretending to be totally reasonable meals. Homemade beef barbacoa tacos. Short-rib potpie. “Weekday” French toast. Make-ahead coconut cake. They might as well be skyscraper blueprints, so improbable is the possibility that I will begin making my own nut butters, baking my own sandwich bread, or turning that fall farmer’s market bounty into jars of homemade applesauce.
It may not start a new war. But it will make it much harder to stop an old one.
For clues to how the Syrian Civil War might finally end—or devolve into an even more nightmarish conflict—look to the congested skies over Syria.
There, the air forces of countries such as the United States, Russia, Turkey, and Syria are all regularly conducting strikes, often at cross-purposes. And there, on Tuesday, Turkish fighter jets shot down a Russian warplane for allegedly violating Turkey’s airspace. As my colleague Marina Koren notes, the episode marks the first time a NATO country has downed a Russian plane in 63 years.

When the birds were reintroduced to New England after a long absence, they chose to live in cities instead of the forests they once called home.
William Bradford, looking out at Plymouth from the Mayflower in 1620, was struck by its potential. “This bay is an excellent place,” he later wrote, praising its “innumerable store of fowl.” By the next autumn, the new colonists had learned to harvest the “great store of wild turkeys, of which they took many.”
Soon, they took too many. By 1672, hunters in Massachusetts had “destroyed the breed, so that ‘tis very rare to meet with a wild turkie in the woods.” Turkeys held on in small, isolated patches of land that could not be profitably farmed. But by 1813, they were apparently extirpated from Connecticut; by 1842 from Vermont; and from New York in 1844.
In Massachusetts—land of the Pilgrim’s pride—one tenacious flock hid out on the aptly-named Mount Tom for a while longer. The last bird known to science was shot, stuffed, mounted, and put on display at Yale in 1847, but locals swore they heard the distinctive calls of the toms for another decade. Then the woods fell silent for a hundred years.
