Persistence and communication skill drive hits

That is to say: keeping productivity equal, the scientists were as likely to score a hit at age 50 as at age 25. The distribution was random; choosing the right project to pursue at the right time was a matter of luck. Yet turning that fortuitous choice into an influential, widely recognized contribution depended on another element, one the researchers called Q. Q could be translated loosely as “skill,” and most likely includes a broad variety of factors, such as I.Q., drive, motivation, openness to new ideas and an ability to work well with others. Or, simply, an ability to make the most of the work at hand: to find some relevance in a humdrum experiment, and to make an elegant idea glow.

Do you pretend to enjoy Pinter? Shakespeare? Stoppard? You’re not alone | Lauren Mooney | Opinion | The Guardian

In one of the most wily marketing tactics I’ve ever seen, Stoppard has talked about his audiences growing stupider until he’s convinced people that anyone who doesn’t like him doesn’t Get It. So now people are reduced to trying to like him louder than each other, to prove to Tom Stoppard that they’re clever. Even though I once watched him fail to use an automatic door. I quite like Tom Stoppard plays, but I do think it’s worth remembering that, much like the girl I was at school with who had a bruised chin for six weeks because a boy she fancied told her to twist it round and round in her hand (true), not everyone who wants you to prove yourself to them deserves it.

The Law School with the Most Influence Will Surprise You

For the Ravel Influence Score, we developed a measure that looks at both quantity and quality of work. Using data from Ravel’s platform we weighed the number of rulings a judge wrote and the number of times those decisions were cited in other opinions. In short, this is an approach that judges judges by way of other judges.

Running boosts neurogenesis (in rats)

Those rats that had jogged on wheels showed robust levels of neurogenesis. Their hippocampal tissue teemed with new neurons, far more than in the brains of the sedentary animals. The greater the distance that a runner had covered during the experiment, the more new cells its brain now contained. There were far fewer new neurons in the brains of the animals that had completed high-intensity interval training. They showed somewhat higher amounts than in the sedentary animals but far less than in the distance runners. And the weight-training rats, although they were much stronger at the end of the experiment than they had been at the start, showed no discernible augmentation of neurogenesis. Their hippocampal tissue looked just like that of the animals that had not exercised at all.

New research shows infections can make your IQ score drop by 10 points

“Our research shows a correlation between hospitalisation due to infection and impaired cognition corresponding to an IQ score of 1.76 lower than the average. People with five or more hospital contacts with infections had an IQ score of 9.44 lower than the average. The study thus shows a clear dose-response relationship between the number of infections, and the effect on cognitive ability increased with the temporal proximity of the last infection and with the severity of the infection. Infections in the brain affected the cognitive ability the most, but many other types of infections severe enough to require hospitalisation can also impair a patient’s cognitive ability. Moreover, it seems that the immune system itself can affect the brain to such an extent that the person’s cognitive ability measured by an IQ test will also be impaired many years after the infection has been cured,” explains MD and PhD Michael Eriksen Benrós, who is affiliated with the National Centre for Register-Based Research at Aarhus BSS and the Mental Health Centre Copenhagen, University of Copenhagen.

Random to dos weigh us down

Just having the opportunity to multitask is detrimental to cognitive performance. Glenn Wilson, former visiting professor of psychology at Gresham College, London, calls it info-mania. His research found that being in a situation where you are trying to concentrate on a task, and an email is sitting unread in your inbox, can reduce your effective IQ by 10 points. And although people ascribe many benefits to marijuana, including enhanced creativity and reduced pain and stress, it is well documented that its chief ingredient, cannabinol, activates dedicated cannabinol receptors in the brain and interferes profoundly with memory and with our ability to concentrate on several things at once. Wilson showed that the cognitive losses from multitasking are even greater than the cognitive losses from pot‑smoking

IQ =/ wisdom

When rational thinking is correlated with intelligence, the correlation is usually quite modest.

Timothy Shriver: how many dimensions to intelligence?

I mean, the idea of intellectual disability comes from the construct that intellect is one-dimensional. We already know that there are multiple intelligences, we just haven't discovered that many of them. Maybe we know about eight or 10 or 12, but my guess is there are a thousand so I love the idea of thinking of a world of different abilities - I use the word diffabilities, some folks don't like it, but I think it invites us to rethink.

Molecular Psychiatry - Genetics and intelligence differences: five special findings

It would be reasonable to assume that as we go through life, experiences—Shakespeare’s ‘whips and scorns of time’—have a cumulative effect on intelligence, perhaps overwhelming early genetic predispositions. However, for intelligence, heritability increases linearly, from (approximately) 20% in infancy to 40% in adolescence, and to 60% in adulthood. Some evidence suggests that heritability might increase to as much as 80% in later adulthood47 but then decline to about 60% after age 80.48
