Is Psychometric g a Myth?
- "As an online discussion about IQ or general intelligence grows longer, the probability of someone linking to statistician Cosma Shalizi's essay g, a Statistical Myth
approaches 1. Usually the link is accompanied by an assertion to the effect that Shalizi offers a definitive refutation of the concept of general mental ability, or psychometric g

A chronic public health disaster.
Complex trauma and toxic stress puts children into a state of reflexive fight, flight, or freeze responses to a perpetually threatening world. The traditional authoritative response only serves to reinforce those behaviours and, perhaps worse, has long-term health consequences:
With an ACE score of 4 or more, things start getting serious. The likelihood of chronic pulmonary lung disease increases 390 percent; hepatitis, 240 percent; depression 460 percent; suicide, 1,220 percent.
One doctor describes it as “a chronic public health disaster”. Remediating this problem is going to require listening, kindness, and parachutes.

The Brain on Trial.
Advances in brain science are calling into question the volition behind many criminal acts. A leading neuroscientist describes how the foundations of our criminal-justice system are beginning to crumble, and proposes a new way forward for law and order.
"We may someday find that many types of bad behavior have a basic biological explanation—as has happened with schizophrenia, epilepsy, depression, and mania." [more inside]

The Triumph of New-Age Medicine "Medicine has long decried acupuncture, homeopathy, and the like as dangerous nonsense that preys on the gullible. Again and again, carefully controlled studies have shown alternative medicine to work no better than a placebo. But now many doctors admit that alternative medicine often seems to do a better job of making patients well, and at a much lower cost, than mainstream care—and they’re trying to learn from it."

Swimming around in a mixture of language and matter, humans occupy a particular evolutionary niche mediated by something we call 'consciousness'. To Professor Nicholas Humphrey we're made up of "soul dust
": "a kind of theatre... an entertainment which we put on for ourselves inside our own heads." But just as that theatre is directed by the relationship between language and matter, it is also undermined by it
. It all depends how you think it.

We Need a General Theory of Individuality
: "One of the unspoken secrets in basic scientific research, from anthropology to zoology (with intervening stops at physiology, political science, psychology, psychiatry, and sociology) is that, nearly always, individuals turn out to be different from one another, and that—to an extent rarely admitted and virtually never pursued—scientific generalizations tend to hush up those differences"

Monogamouse Prairie voles have many vasopressin receptors in the reward centres of their brains. It seems as though these are wired up in a way that causes the animal to take pleasure from monogamy.

Are these people qualitatively different from us? "I would think yes," says Hare. "Do they form a discrete taxon or category? I would say probably -- the evidence is suggesting that.Psychopaths.
They form about 1% of the population. They enjoy the excitement of power. Some choice bits
from Hare's book. The obligatory Bush
link, but, hey, it's got the test sections and the sad truth is that we do have some psychopaths in positions of power, though probably not the Presidency. [Gosh this is getting long] It turns out there's a biological
basis for it. Here's the DSM
description and some detailed
analysis/description (gosh, I
identify with some of those traits!) And here's some AskMe fodder
, "Are You Involved With A Psychopath?" And because of that lust for power... well, it could well be your boss

The Human Speechome Project
- "A baby is to be monitored
by a network of microphones and video cameras for 14 hours a day, 365 days a year, in an effort to unravel the seemingly miraculous process by which children acquire language.". Selected video clips
(PDF, 750KB). To test hypotheses of how children learn, Prof Deb Roy's team at MIT will develop machine learning systems that “step into the shoes” of his son by processing the sights and sounds of three years of life at home. Total storage required: 1.4 petabytes

Predicting who'll benefit from anti-depressants
From the study's abstract: "There are well-replicated, independent lines of evidence supporting a role for corticotropin-releasing hormone (CRH) in the pathophysiology of depression." The NY Times has a bit more readable explanation
(reg-free link) of a recent investigation of into whether there is a genetic explanation for why some people get more from their drugs than others.

FRANCISCO VARELA (1946 - 2001)*
One of the more quietly influential thinkers of our times. A neuroscientist turned immunologist whose formulation of the theory of autopoiesis (with Humberto Maturana) has challenged conventional thinking in areas as diverse as Artificial Intelligence, Ecology and AIDS research.The mathematics of self-reference involves creating formalisms to reflect the strange situation in which something produces A, which produces B, which produces A. That was 1974. Today, many colleagues call such ideas part of complexity theory.
On 28th of May, Varela's own autopoiesis ceased.
