Inequality and life-expectancy

Interesting observation by Paul Krugman in today’s NYT.

Consider, in particular, the proposal to raise the Social Security retirement age, supposedly to reflect rising life expectancy. This is an idea Washington loves — but it’s also totally at odds with the reality of an America in which rising inequality is reflected not just in the quality of life but in its duration. For while average life expectancy has indeed risen, that increase is confined to the relatively well-off and well-educated — the very people who need Social Security least. Meanwhile, life expectancy is actually falling for a substantial part of the nation.

wonder if it applies to the UK also?

Google’s self-guided car isn’t just about automobiles

This morning’s Observer column.

At the ceremony in Mountain View, Google’s co-founder, Sergey Brin, announced the company’s intention to bring autonomous vehicles to the market in five years. In a pre-emptive attack on critics, he pointed out that autonomous vehicles would be significantly safer than human-controlled ones. That seems plausible to me: 40,000 people are killed every year in road accidents in the US and many, if not most, of those are caused by human error. “This has the power to change lives,” Brin said. “Too many people are underserved by the current transport system. They are blind, or too young to drive, or too old, or intoxicated.” He also argued that manual operation of cars was inefficient: autonomous vehicles could make better use of the road and reduce the size of car parks by fitting into smaller areas than humans could get them into.

Ignore the evangelism for a moment and think about what Google has achieved. Its engineers have demonstrated that with smart software and an array of sensors, a machine can perform a task of sophistication and complexity most of us assumed would always require the capabilities of humans. And that means our assumptions about what machines can and cannot do are urgently in need of updating.

This isn’t just about cars, by the way…

Are We Getting Smarter?

My review of James Flynn’s new book – from the Guardian.

Not many academics have a phenomenon named after them, and when it happens they’re mostly hard scientists. In physics there’s the Bose-Einstein Condensate, for example, and the Josephson Effect. Eponymous phenomena are much rarer in the social sciences, for the obvious reason that consensus is harder to reach: the social world doesn’t provide the unambiguous yardstick of a meter reading. All of which makes James Flynn such an interesting exception to the rule, as even in the argumentative world of psychology, the “Flynn Effect” is recognised as an accepted fact…

Anti-Intellectualism in American Life

There’s a lovely, reflective review by Michael Dirda of Richard Hofstadter’s Anti-Intellectualism in American Life on the Barnes & Noble Review site.

I was struck by this quotation from Hofstadter about the philistinism of 19th-century US business, and thinking that nothing much has changed in the last hundred years.

The more thoroughly business dominated American society, the less it felt the need to justify its existence by reference to values outside its own domain. In earlier days it had looked for sanction in the claim that the vigorous pursuit of trade served God, and later that it served character and culture. Although this argument did not disappear, it grew less conspicuous in the business rationale. As business became the dominant motif in American life and as a vast material empire rose in the New World, business increasingly looked for legitimation in a purely material and internal criterion — the wealth it produced. American business, once defended on the ground that it produced a high standard of culture, was now defended mainly on the ground that it produced a high standard of living.

Magic mushrooms

Amazing story in The Economist.

A FEW years ago Francis Schwarze noticed something unusual. Dr Schwarze, who works at the Swiss Federal Laboratories for Materials Science and Technology, in St Gallen, knew that sound travels faster through healthy wood, which is stiff and dense, than it does through the soft stuff left by a fungal attack. But some fungi, he found, do not slow sound. Moreover, the acoustic properties of wood so affected seem to be just what violin-makers desire. So Dr Schwarze had some violins made from the infected wood and discovered that they sounded like a Stradivarius.

But the really lovely bit is that at the end of the piece the magazine provides two audio recordings which enable one to compare a violin made from untreated wood with one that’s made from fungal-infected timber.

Murdoch discovers that he needs ‘parasite’ Google

From today’s Daily Telegraph.

News Corporation plans to reverse an earlier decision to stop articles from its quality papers, such as The Times and The Sunday Times, from featuring in Google’s listings. The effort to stop users from accessing content for free will be watered down, with Google featuring stories in search rankings from next month.

The move comes amid fears that the newspapers’ exclusion is limiting their influence and driving down advertising revenues. Sources claim the change was a “marketing exercise”.

Ah, yes: our old friend, the “marketing exercise”.
