Nerissa: …. superfluity comes sooner by white hairs, but competency lives longer

Thing one

I don’t know what my IQ is, having never knowingly sat a test, but I assume it’s a number just short of infinity. So it was interesting to read, in Carl Zimmer’s book on genetics, She has her mother’s laugh, that IQ is highly correlated to longevity. Not that there’s a genetic link, at least not directly, but it stands to reason. The higher your IQ, the quicker it takes for you to ‘get’ things. This was more or less confirmed by a simple, ingenious brain processing test. Subjects were shown simple shapes flashing very briefly on a computer screen – two vertical lines spaced apart with a horizontal line sitting on top. The participants had to guess which of the two vertical lines was the longest each time. Researchers had worked out that if the images were flashed too briefly, the participants just resorted to guesswork. It required approximately 0.1 seconds for people, on average, to perceive the shape correctly. The key, though, lay in the variation of that perception. It ranged from 0.02 seconds to 0.136 seconds, and researchers found a pretty reliable correlation between accurate perception time and intelligence (presumably measured by IQ – Zimmer doesn’t say). Unfortunately it’s not quite reliable enough, apparently, for us to do away with those pesky, long-winded IQ tests and replace them snappy shape tests, but as mentioned, it does seem to confirm the intuition that intelligence has to do with sharpness and quick-wittedness. Which brings me back to longevity. Some work done in Scotland, which has turned out to be accidentally longitudinal, provides interesting evidence. In 1932 the Scottish government conducted a massive testing program of nearly 90,000 eleven-year-old students – just about the whole of the country’s kids of that age. They were all given a 71-question exam involving decoding, analogising and arithmetic among other things. Over time this ‘experiment’, or what you will, was forgotten, but the records were unearthed in 1997, and then researchers tried to get in touch, some 65 years later, with the ‘kids’ who’d been tested. They managed to gather together 101 elderly citizens in an Aberdeen hall to resit the gruelling test. They found that the score on the original test was a pretty good indicator – 73% – of the score second time around. But there was another interesting finding – the percentage of the test-takers who had scored well and were still alive in 1997 was considerably higher than those who’d scored poorly. Some 70% of the women in the top quarter of scores were still alive, compared to 45% in the bottom quarter:

Children who scored higher, in other words, tended to live longer. Each extra 15 IQ points, researchers have since found, translates into a 24% drop in the risk of death.

Carl Zimmer, She has her mother’s laugh, p296

Why is this so? Smarter people generally know what to do, and are quicker to learn what to do, to live longer, to make more, financially and otherwise, of the circumstances they find themselves in, to be safer, healthier and the like. Stands to reason.

Thing two

A huge fuss is being made of allegations, probably true, of Putin offering and paying bounties to the Taliban to kill American soldiers in Afghanistan. My first reaction to this news was – surely the fervently anti-American and anti-western Taliban were already hell-bent on killing infidel foreigners, and many of the purest ideologues among them would be insulted by the offer of bribes to do so? Then again, many of them would’ve been laughing up their ample sleeves at the thought of being paid by the Russkies, whom they likely consider only slightly less odious and infidelious than the Yanks, to do what they were already heaven-bent on doing. For this reason, it would surely be impossible to prove that any deaths of Americans, or their coalition partners – including Australians – at the hands of the Taliban, could be sheeted home to Putin and his fellow thugs. Even if money traced to Russia appeared in Taliban bank accounts after some atrocity or other, this doesn’t exclude the possibility that the atrocity would’ve occurred in any case. Win-win for the Taliban.

Thing 3

The announcement that the real World Cup will take place in Australia and New Zealand in 2023 makes life a little more bearable, though it’s three years away and I’m not getting any younger. This competition combines two of the most life-affirming enities in life, for me at least – women and soccer. Hopefully we’ll have learned many lessons from Covid-19 by then haha, and at least some of today’s thuggish political leaders will have been placed where they can do no more harm, and we can get on with the more exciting stuff of life, like having fun.
