Natural leaders are made in retrospect

There is no template for the perfect captain. Some of the game's greatest were not identified as such straightaway

So England finished a tour of the West Indies with some widespread areas of consensus. The results were disappointing, the immediate future is dodgy, opportunities were missed and the captain - according to many of the loudest voices - is not a natural leader.

The tour, of course, happened in 2008-09. England lost 1-0. But Andrew Strauss, after that tricky start, became one of the most successful England captains of modern times. Now England are turning to Strauss again, this time as director of cricket, because his leadership credentials are, of course, axiomatic. How quickly people forget views they once vehemently held. Memory is not quite the same thing as intelligence, or even judgement, but it is a good first step on the road towards greater scepticism.

The problem with analysing leadership, especially captaincy, is that people forget how rare it is for successful leaders to stand out as "natural leaders" from the very beginning of their tenure. In fact, the idea of "natural" leadership is usually a retrospective trick - or narrative fallacy - used to make sense of events that, at the time, felt far more contingent and unpredictable.

The most iconic example of great captaincy is also the most misused: Mike Brearley. Perception: Brearley could wander into any team, move gully a bit deeper, and, hey presto, you win by an innings. Reality: by the time Brearley did his Ashes conjuring trick in 1981, he had indeed established a reputation for tactical and managerial brilliance. Crucially, however, that reputation was hard-earned over many years at the coalface. Even more pertinently, Brearley's captaincy could easily have been cut short before anyone noticed how good he was.

Brearley took over as captain of Middlesex in 1971. The seasons of 1971, 1972, 1973, 1974 and 1975 slipped by without Middlesex winning the championship. Brearley has privately told me that in those early seasons he often found the job very difficult. Did he have enough support? Results improved, but not always evenly. In that six-year period, Brearley's gift for patience was tested. So was the constancy of Middlesex. As I write this, only one of the 18 captains of England's first-class counties has been leader for six uninterrupted seasons. Clearly there aren't dozens of Brearleys out there, if only clubs would persevere with them. But if Middlesex had been less patient - or, put differently, less anxious to jump at the first convenience - then England could have been deprived of a superb leader.

Which leads to the second problem with analysing captains. Pundits tend to have a fairly fixed idea of what a natural leader looks like, and then judge the incumbent against their own personal template.

To the alpha-male mindset, the captain should be the leader of the pack, the macho hero. To the Machiavellian world view, a captain should be streetwise and opportunistic. To the progressive, leadership relies on novelty and innovation. To the nostalgic, quite the reverse - the answers always reside in the past. To the laissez-faire, he must be relaxed. To the hard man, a captain must rule with fear.

All valid, none essential. There is no one such thing as the ultimate template for a good captain. All good leaders are different. Indeed, a preparedness to be different - rather than copying someone else - is perhaps the only prerequisite for being any good.

In terms of value added, few managers can match Billy Beane of the Oakland Athletics baseball team. His decisions and the wins that followed have earned Oakland hundreds of millions of dollars (as this article on FiveThirtyEight demonstrates). Despite an emotional temperament, Beane has tried to remove the cult of personality from his decision-making. This is leadership by methodology - thinking, or more accurately calculating, your way to victory.

At the other end of the spectrum stands Sir Alex Ferguson. Anyone who has read Ferguson's autobiography knows that the idea of "copying" Ferguson is inconceivable. His management was founded on the controlling and coercive nature of his personality. Some players seethe with violence. Very occasionally, that survives the transition into management. No leader achieves greatness by punching people. Some, however, clearly benefit from the impression that it would be a grave error for anyone to entirely rule out the possibility of the direct approach. Ferguson ran a pub before becoming a manager. "Sometimes I would come home with a split head or black eye. That was pub life. When fights broke out, it was necessary to jump in to restore order."

Now imagine hearing Pep Guardiola, Roberto Martinez or Arsene Wenger saying that. Inconceivable. Yet all are fine managers.

Which leads us back to Alastair Cook. It is clear that Cook does not fit some preconceptions of cricketing leadership. He is not restless and ingenious, as Michael Vaughan was. He does not cast a magnetic and charismatic presence over the whole arena, as MS Dhoni does. And yet there have been fine captains who possessed neither of those assets.

Last week, after discussing captaincy in the commentary box, the brilliant statistician Andrew Samson passed me two pieces of paper about the records of two captains, each after 31 Tests in charge. The first read:

Runs: 2478
Average: 45.88
Hundreds: 8
Wins: 13
Losses: 9
Draws: 9

The second read:

Runs: 2792
Average: 60.69
Hundreds: 10
Wins: 6
Losses: 9
Draws: 15
Tied: 1

The first is Cook, the second Allan Border, the man who turned around Australian cricket in the 1980s. (Although, of course, the nature of the opposition should always be taken into account with comparative stats.)

Border had also faced criticism about his manner and tactics. But eventually his resilience and run-scoring provided such an inspiring example that his team fell in step
. The two men, so different on the surface - Border was known as Captain Grumpy, where Cook is courteous and self-deprecating - share an epic capacity for endurance. Border outlasted many bowling attacks and, eventually, his critics.

The case against Cook tends to rest on the conviction that he is about to crack, that he can't take much more. This theory is conveniently self-perpetuating because it encourages his detractors to press on with their endeavours. They look eagerly for signs that the strain is becoming too great. This type of thinking contributed to his sacking as ODI captain ridiculously close to the World Cup.

Yet in the West Indies - a patchy tour for England with some poor selection errors - there was no outward sign at all that Cook was wilting. Quite the reverse. His hundred in the third Test was almost faultless.

Many bowling attacks have pinned their hopes on Cook cracking, only to find the wait inconveniently lengthy. I wonder if the detractors of Cook's captaincy will experience a similar story.

Post-crash economics: some common fallacies about austerity


Propositions in economics are rarely absolutely true or false – what is true in some circumstances may be false in others

The period since 2008 has produced a plentiful crop of recycled economic fallacies, mostly falling from the lips of political leaders. Here are my four favourites.
The Swabian Housewife: "One should simply have asked the Swabian housewife," said German chancellor Angela Merkel after the collapse of Lehman Brothers in 2008. "She would have told us that you cannot live beyond your means."
This sensible-sounding logic currently underpins austerity. The problem is that it ignores the effect of the housewife's thrift on total demand. If all households curbed their expenditures, total consumption would fall, and so, too, would demand for labour. If the housewife's husband loses his job, the household will be worse off than before.
The general case of this fallacy is the "fallacy of composition": what makes sense for each household or company individually does not necessarily add up to the good of the whole. The particular case that John Maynard Keynes identified was the "paradox of thrift": if everyone tries to save more in bad times, aggregate demand will fall, lowering total savings, because of the decrease in consumption and economic growth.
If the government tries to cut its deficit, households and firms will have to tighten their purse strings, resulting in less total spending. As a result, however much the government cuts its spending, its deficit will barely shrink. And if all countries pursue austerity simultaneously, lower demand for each country's goods will lead to lower domestic and foreign consumption, leaving all worse off.
The government cannot spend money it does not have: This fallacy – often repeated by British prime minister David Cameron – treats governments as if they faced the same budget constraints as households or companies. But governments are not like households or companies. They can always get the money they need by issuing bonds.
But won't an increasingly indebted government have to pay ever-higher interest rates, so that debt-service costs eventually consume its entire revenue? The answer is no: the central bank can print enough extra money to hold down the cost of government debt. This is what so-called quantitative easing does. With near-zero interest rates, most western governments cannot afford not to borrow.
This argument does not hold for a government without its own central bank, in which case it faces exactly the same budget constraint as the oft-cited Swabian housewife. That is why some eurozone member states got into so much trouble until the European Central Bank rescued them.
The national debt is deferred taxation: According to this oft-repeated fallacy, governments can raise money by issuing bonds, but, because bonds are loans, they will eventually have to be repaid, which can be done only by raising taxes. And, because taxpayers expect this, they will save now to pay their future tax bills. The more the government borrows to pay for its spending today, the more the public saves to pay future taxes, cancelling out any stimulatory effect of the extra borrowing.
The problem with this argument is that governments are rarely faced with having to "pay off" their debts. They might choose to do so, but mostly they just roll them over by issuing new bonds. The longer the bonds' maturities, the less frequently governments have to come to the market for new loans.
More important, when there are idle resources (for example, when unemployment is much higher than normal), the spending that results from the government's borrowing brings these resources into use. The increased government revenue that this generates (plus the decreased spending on the unemployed) pays for the extra borrowing without having to raise taxes.
The national debt is a burden on future generations: This fallacy is repeated so often that it has entered the collective unconscious. The argument is that if the current generation spends more than it earns, the next generation will be forced to earn more than it spends to pay for it.
But this ignores the fact that holders of the very same debt will be among the supposedly burdened future generations. Suppose my children have to pay off the debt to you that I incurred. They will be worse off. But you will be better off. This may be bad for the distribution of wealth and income, because it will enrich the creditor at the expense of the debtor, but there will be no net burden on future generations.
The principle is exactly the same when the holders of the national debt are foreigners (as with Greece), though the political opposition to repayment will be much greater.
Economics is luxuriant with fallacies, because it is not a natural science like physics or chemistry. Propositions in economics are rarely absolutely true or false. What is true in some circumstances may be false in others. Above all, the truth of many propositions depends on people's expectations.
Consider the belief that the more the government borrows, the higher the future tax burden will be. If people act on this belief by saving every extra pound, dollar, or euro that the government puts in their pockets, the extra government spending will have no effect on economic activity, regardless of how many resources are idle. The government must then raise taxes – and the fallacy becomes a self-fulfilling prophecy.
So how are we to distinguish between true and false propositions in economics? Perhaps the dividing line should be drawn between propositions that hold only if people expect them to be true and those that are true irrespective of beliefs. The statement, "if we all saved more in a slump, we would all be better off," is absolutely false. We would all be worse off. But the statement, "the more the government borrows, the more it has to pay for its borrowing," is sometimes true and sometimes false.
Or perhaps the dividing line should be between propositions that depend on reasonable behavioural assumptions and those that depend on ludicrous ones. If people saved every extra penny of borrowed money that the government spent, the spending would have no stimulating effect. True. But such people exist only in economists' models.
