Trust the experts? Not the ones who failed to foresee the crash

Experts aren't infallible. Prone to overconfidence and groupthink, some of them make catastrophic er

Capitalism is in crisis: the US economy has stalled, the eurozone is imploding, elected European leaders are falling on their swords. Meanwhile, the Middle East is in turmoil: dictatorships are collapsing, Islamists are on the rise, Israel is considering military action against Iran. Oh, and did you know that the world may be on the brink of "runaway" climate change?

We are - to borrow from the ancient Chinese curse - living in interesting times. So how do we make sense of it all? The answer, it seems, is to ask the experts. Scientists, doctors, lawyers, economists, accountants, diplomats, generals - these well-qualified, well-spoken experts are invited on to our television screens, and offered columns in our leading newspapers. We crave their guidance, their wisdom and their insight.

But how much can we trust their judgement? Journalists are often blinded by a grand title or a long string of letters after a name. Most reporters - even specialists such as business or environment editors - need help understanding particular issues. Journalists tend to have degrees in English or history, rather than, say, econometrics or particle physics. The 24-hour news cycle has added an extra dimension: in the words of a former boss at Sky News, they need to"feed the beast".

"Illusion of skill"

Experts aren't infallible. Prone to overconfidence and groupthink, some of them make catastrophic errors. In addition, any "argument from authority" or argumentum ad verecundiam - where a proposition is believed to be true because an authoritative person says it is - is not one we should accept uncritically. Empirical evidence is what matters.

Then there is the "illusion of skill", to quote the Israeli psychologist and Nobel laureate Daniel Kahneman (himself an expert!). In his new book, Thinking, Fast and Slow, Kahneman cites a Duke University survey of stock-market forecasts by a group of chief financial officers of large US corporations. "The conclusion was straightforward," he writes. "[F]inancial officers . . . had no clue about the short-term future of the stock market; the correlation between their estimates and the true value was slightly less than zero." In other words, when these CFOs predicted that the market would go down, "it was slightly more likely than not that it would go up". The effect of this was that their forecasts "were worthless".

Logical fallacies and cognitive illusions aside, however, the fact is that some complex arguments cannot be decided without input from a qualified or expert source. But expertise and qualifications cannot trump track record and past performance. If an expert - be it a climate scientist, a stock trader or an intelligence analyst - makes a judgement call or offers an opinion, a forecast or a prediction, shouldn't it be held against him or her if it turns out to be flawed or incorrect? Shouldn't the power and influence of the expert also come with some responsibility? And shouldn't journalists exercise their own judgement when seeking out and selecting so-called experts for comment?

Take David Albright, the former UN weapons inspector and founder of the Institute for Science and International Security (Isis). In recent weeks, he has been quoted by various US newspapers as claiming that Iran is building nuclear weapons. His biography on the Isis website touts him as the "go-to guy for media people seeking independent analysis". But what if we want accurate and reliable analysis? Albright's assessment of the Iraqi WMD threat was spectacularly wrong. In November 2002, he suggested that Saddam Hussein could be involved in a "clandestine nuclear weapons effort"; in February 2003, he flatly declared that: "In terms of the chemical and biological weapons, Iraq has those now." Eight years on, should US journalists really be giving such weight to his views on Iran's nuclear programme? Why not instead turn to the handful of experts who were right about Iraq?

Dr Doom

The same point applies to the financial crisis. Those economists - who clung to neoclassical theories of "rational expectations" and "efficient markets" while failing to spot the gathering financial storm - should have been discredited in recent years. Most of them haven't been, while those who got it right are ignored.

Take Nouriel Roubini, professor of economics at New York University's Stern School of Business. In 2006, at a speech in Davos, the Turkish-born Roubini warned that Italy would struggle inside the eurozone and might "end up like Argentina" - prompting an irate Italian finance minister on the panel to cry, "Go back to Turkey." In the same year, in a speech to the IMF, he predicted that the US "was likely to face a once-in-a-lifetime housing bust, an oil shock, sharply declining consumer confidence, and, ultimately, a deep recession" - earning him the soubriquet of "Dr Doom". He has, of course, been vindicated on both issues.

So isn't it odd to see finance ministers across Europe - including George Osborne - studiously ignoring Roubini's advice? The professor's preferred solution is "for those countries that have not lost market access . . . to introduce new short-term fiscal stimulus while committing to medium-term fiscal austerity", a position dismissed by Osborne, who has no background in economics, as "ludicrous" and "on the outer fringes of the international debate".

Experts, including economists and weapons inspectors, have a role to play - but within limits. They are not above or beyond accountability; their opinions and judgements should be open to scrutiny, criticism and even ridicule.

The litmus test of expertise is not how many letters or titles a given expert has after his name, but whether or not he has a proven track record of sound analysis and vindicated judgement.

It's bad enough that the 'experts' who got us into this mess adorn our TV screens at very turn. But it doesn't stop there. As we now seem to think we can shoehorn in 'experts' to run countries - as in Italy and Greece.

And can we stop calling them technocrats - I prefer the term 'bankers' - keeps us focussed on why they have been, ahem, selected, for these jobs...

finally some sense- Roubini though? You think his predictions were good? who was he reading i wonder lol!!get the heavyweights on board- look t what jim rodgers has been saying for years about western economies.
This stuff ain't hard...

But of course the same concern wouldn't be applicable to Global Warming, would it?
After all, the so-called 'experts', who make their living by exagerrating Global Warming have been making predictions that the sea is going to rise by 13 feet in the next century when in fact it has been rising by less than a centimetre in ten years. They have assured us temperatures will rise by 'up to' 6c, but in fact have risen by just .6c in the last 50 years. All of this 200 years since the Industrial Revolution.
What these experts won't tell us is the inconvenient facts that undermine their claims and their real political agenda; for example, that simple cooking fires in India emit more Co2 that all the cars and trucks in USA. in any day or year.

Experts assured us until 1980 that the idea of plate tectonics was ridiculous.

Experts assured us until 5 years ago that they sure that all dinosaurs werre cold blooded.

So I agree that a so-called experts advise and opinions need to treated with as much scepticism as anyone else's.

Fed Moves on Long-Term Interest Rates to Spur Growth

By BINYAMIN APPELBAUM
Published: September 21, 2011

WASHINGTON — The Federal Reserve announced a new plan Wednesday to stimulate growth by purchasing $400 billion in long-term Treasury securities with proceeds from the sale of short-term government debt, defying Republican demands to refrain from new actions.

Fed Press Release

Readers’ Comments

In extending its campaign of novel efforts to shake the economy from its torpor, the Fed said that it was responding to evidence that there was a clear need for help.

“Growth remains slow. Recent indicators point to continuing weakness in overall labor market conditions and the unemployment rate remains elevated,” the Fed said in a statement that listed its reasons for worry about the anemic condition of the American economy. “Household spending has been increasing at only a modest pace in recent months.”

The central bank said in a statement that the program was aimed at reducing the cost of borrowing for businesses and consumers, including the cost of mortgage loans. It hopes that the lower rates will encourage companies to build new factories and hire more workers, and consumers to start spending again on homes and cars and clothes and vacations.

Specifically, the Fed said that by June 2012 it would sell $400 billion in Treasury securities with remaining maturities of less than three years and purchase roughly the same amount of securities with maturities longer than six years. It said the result would move the average maturity of the bonds it holds to about 100 months from 75 months.

Separately, the Fed said it would resume direct efforts to help the mortgage market by reinvesting the proceeds of its existing investments in mortgage-backed securities into new mortgage-backed securities, rather than putting the money in Treasuries.

Three members of the Fed’s 10-member policy-making committee dissented from the decision: Richard Fisher, president of the Federal Reserve Bank of Dallas; Charles Plosser, president of the Federal Reserve Bank of Philadelphia; and Narayana Kocherlakota, president of the Federal Reserve Bank of Minneapolis. The members were the same who opposed the Fed plan announced in August to hold short-term interest rates near zero until at least 2013.

The new effort is an experiment without a direct precedent, although the Fed tried something similar in the 1960s. Essentially, the Fed hopes to drive down rates not by expanding the size of its portfolio, as it has done twice in recent years, but by shifting its money into riskier investments. By reducing the supply of long-term Treasuries, the Fed intends to force investors to accept lower rates of return on a wide range of riskier investments.

Economists project that the effort could reduce interest rates by a few tenths of a percentage point, a significant increment when multiplied by the vast extent of borrowing. The forecasting firm Macroeconomic Advisers estimated in advance of the Fed’s announcement — based on its best guess about the details of such a program — that the Fed’s efforts could add about 0.4 percentage points to economic output and create about 350,000 jobs.

The Fed already is engaged in an enormous effort to stimulate growth. The central bank has held short-term interest rates near zero since December 2008. To further reduce long-term rates, it has amassed more than $2 trillion in government debt and mortgage-backed securities. And the Fed announced after the most recent meeting of its policy-making committee in August that it intended to hold short-term interest rates near zero until at least the middle of 2013.

The Fed had previously said only that it would maintain rates near zero for an “extended period,” and a new study by the Federal Reserve Bank of Cleveland found that the change in language had a significant impact. Specifically, by convincing investors that short-term rates would remain low, the Fed succeeded in lowering long-term rates — which are based in large part on expectations about the level of short-term rates throughout the longer period. Rates on the benchmark 10-year Treasury note, for example, declined by about 0.20 percentage points, the study found.

But the economy remains weak. Gross domestic product expanded by only 0.7 percent in the first half of the year, roughly the rate of population growth, meaning that Americans experienced no increase in average wealth. More than 25 million people were unable to find full-time jobs last month. Most of them could not find work of any kind. And concerns about the economic health of Europe and the political health of Washington have depressed measures of consumer confidence to the lowest levels since the depths of the 2008 crisis, endangering prospects for faster growth in the coming months.

At the end of August, Mr. Bernanke told an annual policy conference in Jackson Hole, Wyo., that the committee would meet for two days in September, rather than one, to consider additional action.

The Fed still has “a range of tools,” Mr. Bernanke said in a mid-September speech in Minneapolis, and, echoing his constant refrain in recent years, he added that the committee was “prepared to employ these tools as appropriate to promote a stronger economic recovery in a context of price stability.”

Investors expected the Fed’s move, modeled on a 1960s program called Operation Twist. Yields on the benchmark 10-year Treasury note hovered around the record low of 1.88 percent in recent days, reflecting market confidence that the central bank would act and uncertainty about the health of the economy.

But studies have found the Fed’s success in reducing rates through its rounds of asset purchases have not yielded the full measure of predicted benefits. Mortgages and small-business loans may be cheap, but because lenders remain cautious, the loans are not easy to get.

Fed officials convened to reach their decision in an environment of heightened political pressures. As Democrats and Republicans battle over the role of government in improving the economy, both parties have sought to influence the decisions of the central bank.

Republicans have been increasingly vocal in their insistence that the Fed should stop trying to bolster growth. They argue that the central bank’s existing efforts are not helping and that new efforts could have negative consequences. Republican presidential candidates have made criticism of the Fed a central theme of the early campaign, and Republican leaders in the House and Senate sent a letter Tuesday to Mr. Bernanke warning against new measures.

“We have serious concerns that further intervention by the Federal Reserve could exacerbate current problems or further harm the U.S. economy,” said the letter, signed by Senator Mitch McConnell of Kentucky, the Republican leader; Senator Jon Kyl of Arizona, the Republican whip; House speaker John A. Boehner of Ohio; and Representative Eric Cantor of Virginia, the majority leader.

Some Democrats, meanwhile, have accused the central bank of being too cautious. Representative Barney Frank of Massachusetts, the ranking Democrat on the House financial services committee, has proposed legislation removing the presidents of regional Federal Reserve banks from their seats on the Fed’s policy-making committee. They tend to be more concerned about inflation and less concerned about unemployment.

The 12 presidents of regional banks, who are elected in part by local businesses, currently fill five seats on the committee on a rotating basis. Currently, there are 10 members on the panel with two vacancies. Mr. Frank has described the participation of the regional presidents as undemocratic, and said that the dissent of three of the regional presidents from the August decision to announce an intent to keep short-term rates near zero — the largest number of dissents in about two decades — was “stark evidence” that they were constraining the Fed’s effectiveness.

Part of the problem is that the MSM loves to hype personalities instead of actual economic facts. It's the War of Economists:

Thomas Friedman says Rick Santelli's an idiot on CNBC.

The Huffington Post does a feature on Roubini and spends much it saying what a babe magnet he is (with said picture of him and the babes).

Steve Keen talks about writing off the debt and spends much of his time "debating" some neoclassical economist over lots of points that many people don't know.

Now, what do the above have to do with discussing actual facts about the economy? Nothing whatsoever.The average person doesn't know who Greenspan is. Who the hell is Minsky, and why should I care? All I care about paying my rent.

The MSM insists on sexing up the issue. This means that they're making the problem worse instead of doing their jobs.

Naturally, if you complain to these media corporations, you'll get the usual "if you don't like it, turn it off" response. All these various "experts" are doing is filling airtime. And many get paid extremely well for it. So how many are going to say no to corporate money? Very few.

If you read JK Galbraith's book entitled 'Money' (published in 1975) it explains a lot about the crisis we are now in. It's not new - it has been repeated many times over.

The question is why?

gosh axmed, you're easily impressed... posters at NS have been pointing out the very substance of this article for MONTHS... you're not a stooge by any chance- we are after all in a political world, and even area heads have bosses.

Interesting article. Was not very impressed with the last para tho:

"The litmus test of expertise is not how many letters or titles a given expert has after HIS name, but whether or not HE has a proven track record of sound analysis and vindicated judgement."

Can only men be experts Mehdi?

I listen to 3 people in the media and they are usually right. They are Robert Peston, Andrew Neil and Ian Hislop. This trio could run the country no problems.

Some experts that have the worst judgement in my opinion are Will Hutton, David Blanchflower and Anatole Kaletsky .

My personal opinion, no ill feeling intended.
