Is heritability of IQ non-linear?

haven’t read the entire thing yet, but i’ll try to this weekend. the abstract suggests a very strange result however at first glance. the researchers found that heritability of IQ depends on the socio-economic status of the parents. wtf?

Scores on the Wechsler Intelligence Scale for Children were analyzed in a sample of 7-year-old twins from the National Collaborative Perinatal Project. A substantial proportion of the twins were raised in families living near or below the poverty level. Biometric analyses were conducted using models allowing for components attributable to the additive effects of genotype, shared environment, and non-shared environment to interact with socioeconomic status (SES) measured as a continuous variable. Results demonstrate that the proportions of IQ variance attributable to genes and environment vary nonlinearly with SES. The models suggest that in impoverished families, 60% of the variance in IQ is accounted for by the shared environment, and the contribution of genes is close to zero; in affluent families, the result is almost exactly the reverse.

Megan Fox and Rain

alg_megan_fox

here ‘s the background. about a year ago, rain was interviewed after filming an ad in beijing saying, “Megan Fox is the best, her eyes and body are really attractive” when asked a question about sexy women.

and recently when she was in australia, megan fox said of rain, “There’s this Korean Justin Timberlake named Rain. And I’m really on this situation right now, I’m trying to fix this up.” this got a lot of play on entertainment websites b/c it’s big news who megan fox dates. (more…)

Boogie Town – wtf

VERY weird trailer (courtesy AAM)

it’s awesome that ppl from kaba and quest are in the movie. not so sure about the plot tho. do all dancers in the future need to be augmented w/ superpowers and inherit the gene for blue eyes? really?

but regardless, this could be a pretty big deal. i mean, sure it might be reminicent of a bboy exploitation film from the 80s, but it’s got nationally recognized asians as a very prominent part of the cast and talent. and they aren’t all doing martial arts! and they aren’t gangsters! and they aren’t geeks/nerds! and they speak english! has hollywood lost it’s freakin mind?

it’s apparently billed as a hip-hop westside story. so i’m wondering… exactly how is the riff/mercutio character gonna get killed? i mean is the bernardo/tybalt character gonna dance him to death? lol.
