Bias

Thought-provoking article in The Guardian today, about how even medical research can end up with an unreliable consensus skewed by influential reviews:

A small number of review papers funnelled large amounts of traffic through the network. These acted like a lens, collecting and focusing citations on the papers supporting the hypothesis.

Worse, science can be "spun":

One paper reported no beta amyloid in three of five patients with IBM, and its presence in only a "few fibres" in the remaining two patients; but three subsequent papers cited this data, saying that it "confirmed" the hypothesis.

This is an exaggeration at best, but the power of the social network theory approach is to show what happened next: over the following 10 years these three supportive citations were the root of 7,848 supportive citation paths, producing chains of false claim in the network, amplifying the distortion.

This leads one on to consider the implications of social network theory. I suppose it's a talent for this that helped Mao and Stalin rise, but also it may explain how people in other fields (e.g. finance and banking, the media) can be both successful and dangerously dumb. (Remember Mao's bright idea of 1958, culling sparrows because they ate crops? The resulting explosion in the crop-gobbling insect population forced him to ask Russia for thousands of birds to restock).

And have you watched the celeb version of "Who wants to be a millionaire?" and been struck by the ignorance of some of them? Yet they know enough (of what they need to know) to make a sight more than most of us. The technique seems to be, get the job first, then learn how to do it from those around you. Duffers try to learn first, then apply for the post, by which time it's gone. Look at chancer Blair as against plod-towards-it Brown. (Some say that Blair has never read a book; but then, he doesn't need to. As Disraeli said, "When I want to read a book, I write one.")

Connected to social network theory is Cass Sunstein's notion of "group polarisation", where like-minded people get together, not only reinforcing their views but making them more extreme. I suppose this has implications not just for political caucuses and media advisers, but for how we choose our newspapers.

And what blogs we read.

Happy or clever

"If you're so clever, why aren't you happy?" a friend's mother would say to him.

I'd turn that around. I think that for some, being unhappy is what stimulates the mind. That doesn't mean that I believe it's a good thing; it's just that your brain accelerates, looking for a way to survive. Having taught Looked After Children for a couple of years, I'd say that typically, although they were academic under-achievers, they were unusually sharp for their age in other ways. Maybe that's also why girls from broken homes become sexualised earlier.

But the one thing that all this cleverness doesn't address is the root of the cleverness itself. It may seem an impertinence to judge people one hasn't met - though that is the bread and butter of the modern media - but would you regard, say, Stephen Fry or Dawn French as happy, well-balanced people?

A clever person is more likely to out-argue you than to put right anything about themselves. I've read that psychoanalysts find highly intelligent patients the hardest to cure; and that successful entertainers avoid seeking a solution for their neuroses, because it might turn off the tap of their talent.

I hope for a world that is fit, not for heroes nor for geniuses, but for the dully contented.

Our Achilles heel?

The Contrarian Investor suggests that the next market destabilizing factor is the need for minor European nations to refinance.

Nail on head

The cure will be to increase the median wage, and to stop the transfer of the national income to fewer and fewer hands. For that is how the system is set up today. It is not the result of 'free markets' but a sustained transfer of wealth through regulatory and tax policies, and a pernicious corruption of the nation most significantly starting in 1980, although a case has been made for 1913.

Turkeys Reunited

Goldman Sachs are on the brink of a massive new consultancy contract, it is rumoured. An unnamed source within the organisation hints that ITV may be asked to take over Lloyds Bank and Northern Rock.

"ITV's £105 million operating loss is peanuts," said the trader. "We at GS paid out £1 billion more in bonuses than we got in bailout money last year. The guys at ITV don't think big enough. If they don't wise up fast, they could be in danger of making a profit."

This alleged development lends credence to the long-standing speculation that the American and British governments are secretly planning the creation of a "Super-Turkey", merging all remaining manufacturing, banking and finance into a giant loss-making enterprise that will employ increasing numbers of the population until everybody starves.

The power of ignorance

If we were as ignorant of what goes in political circles, as country folk were in the Middle Ages, how could we tell which party was in power? Unless we had been pressed into military service, wouldn't we pretty much go on as usual from day to day? The papers rage about tax but most people haven't a clue how much they pay in income tax and NIC on their salary slips. Is it OK, rational, to be politically apathetic? Isn't personal action to improve one's life 100 times more important than who you vote for every 5 years?

1984

It hasn't happened the way Orwell said it would, they keep saying. Yet:

The Children’s Secretary set out £400million plans to put 20,000 problem families under 24-hour CCTV supervision in their own homes.

They will be monitored to ensure that children attend school, go to bed on time and eat proper meals.
