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

"People prefer music that deviates from perfection in a natural way." Researchers into rhythm
are trying to figure out the nature of these deviations, and what implications this has for audio engineering and neuroscience.
Neuroscientist Lise Eliot finds that claims of sex differences fall apart.
In one study, scientists dressed newborns in gender-neutral clothes and misled adults about their sex. The adults described the "boys" (actually girls) as angry or distressed more often than did adults who thought they were observing girls, and described the "girls" (actually boys) as happy and socially engaged more than adults who knew the babies were boys. Dozens of such disguised-gender experiments have shown that adults perceive baby boys and girls differently, seeing identical behavior through a gender-tinted lens. [more inside]
Test My Brain
was set up by Harvard's Vision Lab and Social Neuroscience and Psychopathology Lab. There are five tests online at the time of this post; take one and maybe you'll learn something about yourself that you may not have known (other than your special ability to slack off on MetaFilter when you should be working). At the same time, you'll be helping researchers collect data from a wide range of subjects. One of the collaborators, Professor Ken Nakayama, is also responsible for creating these online tests
for faceblindness. [previously] [more inside]
Brain Researchers Open Door to Editing Memory
: spotless minds might be closer than we think.
A team of researchers at the ATR Computational Neuroscience Laboratories
in Kyoto have managed to reconstruct black-and-white visual images
from an fMRI scan of a test subject's brain. Some more examples of the recovered data.
The organization responsible claims that the technology to record thoughts and dreams is just around the corner. [more inside]
Recent neuroscience research suggests that Democrats and Republicans are not nearly as far apart as they seem (NYT).
Will an awareness that we are conning ourselves to feel alienated from each other help to close the political gap? Or, are we conned by science and the media?
