What have risky loans and Thunderbirds' Tracy Island got in common? Everyone wanted them because everyone else wanted them. It's how bubbles are made and why we are always doomed to see them burst, says Michael Blastland.

Say what you like about the new pariahs, bankers' reputations are shredded anyway. The libel laws might as well be suspended.

And why? Because they were greedy and stupid, obviously. The reasons are transparent and judgement quick. Thus is the moral high ground suddenly over-crowded. How easy, how comforting to know that vast error was simple. J M Keynes wrote that buying shares was like a bonny baby competition, in which you don't choose the baby you think prettiest, but the baby you think other people will think prettiest

This is no defence of bankers. But it can be argued that the easy explanation is inadequate and, left unchallenged, will hasten the next crash. Unfortunately, a better explanation incriminates us all.

This argument - of a link between the suits who blew it and the rest of us - is made by way of babies, Christmas toys and ants.

One of the first habits we acquire is to glance at mum before deciding how to react to what's around us. It is called social referencing. How do I know if I should be afraid or eager? I check the reaction elsewhere.

That characteristic equips us well. To find out what others think before we act makes sense: they might know something.

Even if they know nothing, other people who think a thing worth having will make us more inclined to want it too. The kid who craves those new, weird trainers, wants them in part because every other kid wants them. Never mind that they wreck his feet.

It's a habit that feeds fashion and influences more than just the clothes we wear. It is what makes markets of all kinds not simply a matter of a seller with a product at a price and a buyer with a budget, but a buyer who has an eye on other buyers, who are themselves looking over their shoulders.

So the market can become detached from any supposed objective quality in the product, not through stupidity, but through the everyday circular psychology of living and choosing among others.

To illustrate this, some economists have turned to ants. Place two equal piles of food outside the nest, and the ants find both, but nearly all prefer just one. Pile A is all the rage. This is because one trail is soon reinforced by others and becomes dominant.

Then they suddenly switch. Now pile B is all the rage. That's because a few lost their way and wandered to pile B, others picked up this trail and reinforced it, the fashion changed.

Similarly, people in all kinds of markets often tend to converge on one belief. On Wednesday, the top 12 toys for this Christmas were unveiled. But who can say which will be this year's Furby or or Blanket Time Iggle Piggle - sell-out toys from Christmases 1998 and 2007 respectively? At least Brains, Thunderbirds' resident bespectacled thinker, might have had an inkling of how bubbles are blown and burst after Thunderbirds' Tracy Island toy sold out in the run up to Christmas 2000.

This year's must-have Christmas toy will often run out because no one knows what it will be in advance. Everyone will want it but only because everyone wants it, and that's apparent only late on in the year. It will happen again and not because there'll be a new generation of fools, but mainly because we find comfort, reassurance and momentum in groups

Parents may tut-tut at the quality all they like. Newspapers may complain of profiteering at children's expense. But there need be no conspiracy.

The principle - that our choices are influenced by others and we often tend to herd together - applies to innumerable areas of human behaviour. What we do depends on what others do, and what they do depends on us. Thus can we even find ourselves all doing something that no individual thinks wise or best, like paying with the shirts off our backs for a new house.

From here, it is a short step to the banker assessing risk. Risk is often not an objective fact either. Even the most prudent lending can become risky in a vicious downturn. Even a 110% mortgage can turn out OK in a boom.

So how do bankers decide what's excessively risky? They might pretend they have a formula, but mostly they do what we all do, and look to other people's behaviour, or at an index of risk which can be no more than the sum of other people's beliefs.

They look at other banks making similar decisions, and they look at us. And if everyone else is betting with confidence, they will too. Their expectations shape the facts as they see them. Market confidence, so they think, is their insurance.

Eventually, of course, belief alone isn't enough, and there are always a few outsiders protesting that not all is as it seems, a view that one day, like the ants' preference for pile B, suddenly prevails.

But if the initial belief was inherently and obviously stupid and led to inevitable destruction, no one would fall for it. They might have been greedy, but so stupidly greedy as to cut their own throats?South Sea Bubble is perhaps British history's most famous pop

Unlikely. The circumstances were in principle not unusual. They arose from social referencing in the strange, small world of new financial products.

We repeat this kind of behaviour in one form or another with astonishing frequency and "stupidity" doesn't begin to help us understand it. Bubbles that pop have been a feature of economic life ever since a boom in red mullet in ancient Rome. Railways, loans to Latin America, seaside piers, South Seas trade, Asian currencies, tulip bulbs, American real estate, the internet, you name it, getting carried away on the tide is in our blood.

A remarkable feature of this tide - often noted - is how we use our intelligence to explain that the latest boom is different, why last time was plain stupid, but this time some new fact has changed the rules. Seems to me that process has started already.

Then, as this year's Nobel prize-winning economist Paul Krugman has said, people believe the new stories because everyone important tells them. People tell these stories because everyone important believes them. Holding the consensus view becomes a litmus test of being taken seriously. What ultimately drives disaster is circularity.

So think the whole episode stupid if you will. After all, right now, everyone else thinks so too. And they must know something.

But when? Some say 10-15 years. In my view, it is here already, driven in part by the facts, true, but also by what people think others now believe, an excessive collective mood that could cause real damage. This time, it's called pessimism.
