I said this to my brother-in-law (Dave) at the weekend – and then went on to clarify. Other than the two articles in the new Wired magazine that I’ve commented on already, the other very interesting read was one quite compelling explanation for the current financial crisis and it is indeed to do with a man called Dave.
David X Li is a Chinese mathematician who emigrated to Canada and while working for Barclay’s Capital in 2004 invented a new formula for managing risk – which ultimately led to the growth of the subprime mortgage market. The Wired article gives an excellent analogy (you can read here) to explain the thinking behind the formula but the bottom line is that although, on face value, it is a persuasive concept it didn’t work and now we are all paying the price.
The big problem here however is that the formula wasn’t just tested out by one or two traders – it was adopted by every single trader. As the article states more accurately, “David X Li can’t be blamed. He just invented the model. We should blame the bankers who misinterpreted it”

To me this is one of the biggest and most explosive examples of ‘Groupthink’ in history. The speed with which the world now operates and the complexity and immediacy of the computer and communications systems we are surrounded by, means this was a scenario just waiting to happen. There is also something here about American business culture in particular that I have personally experienced, having worked for US run organisations for a fair chunk of my career. That ‘can do’ attitude that has built many a successful business can also backfire spectacularly when it is at the expense of ‘critical thought’ and valid opposing viewpoints.
These same issues can apply on an even larger scale and make concepts such as ‘collective intelligence’ and the ‘wisdom of crowds’ – that are often fuelled by social media mechanisms but not always governed by clear thinking – as potentially quite dangerous. On this occasion, the US pioneering on the bleeding edge of technologies has provided a massive wake-up call!

Similarly, I have always kept a close eye on things like voice-to-text translation. Watching my father and aunt trying to communicate these days would illustrate why. Neither of them has any natural hearing left and even the most advanced digital hearing aids are not much use to them anymore. So they have to communicate using a combination of lip reading and pen and paper – which is not the most conducive way to have a meaningful and useful discussion.
Is history repeating itself once again? Our global crisis appears to be inciting ‘mob rule’ on a global scale. Firstly we have ‘the mob’ baying for the blood of the bankers the world over and our elected politicians who are, by and large, complicit in this debacle echoing ‘the mob’ and feeding its anger still further as if to distract from their own culpability. And then you have the appeasement – Politicians using money that they don’t have to keep the mob happy and reduce the possibility of social unrest on their watch whilst building up a bill that will still have to paid on someone else’s.
I read the sample copy that came with the Times at the weekend and there are some interesting features in the first issue, including a timeline of potential developments over the next few decades. The article that will get me buying the first issue though (as I’m sure was the strategy of the Editor) is the true account of the
