Slightly OT, but @AJ, will Socky be appearing in your teaching next term? For those who don't know Socky, check out "The Adventures of Socky and Alan":- http://www.youtube.com/watch... - Graham Steel
Hmm, no plans for Socky on FriendFeed at this stage. He crops up in my weekly statistics videos. Of course, if there's enough demand... - AJCann

What Is the Heritability of Being an A--hole? [Mike the Mad Biologist]

I've finished reading Richard Nisbett's
Intelligence and How to Get It: Why Schools and Cultures Count
, which is a wonderful counterargument to Charles Murray's (and others') genetic conservatism (my phrase, not Nisbett's): intelligence, typically ascertain using IQ, is highly heritable, so there's little point in spending excessively (whatever that means) on educating most people, since it won't make a difference.

Nisbett demolishes this argument in detail (I've also touched on some of these issues in the context of obesity), so I won't rehash the book here, except to note that when one closely examines the adopted twin studies often used to support the genetic conservatism argument, they are really weak and unduly overemphasize the role of (additive) genetic variation. (Go read the book, since Nisbett makes the argument far more cogently that I can).

What I find obnoxious whenever I listen to or read Murray and his genetic deterministic ilk is the implicit assumption that, you, Dear Reader or Listener, are part of the genetic overclass; it's those other people, not in attendance, who are the lumpen üntermenschen. Not only is this one of the oldest rhetorical cons going, it's incredibly arrogant.

Which, for me, inevitably raises a question that mysteriously is never asked:

The Brain Can Change Itself: Evidence From Impossible Phantom Limb Movements

Fascinating research - often involving phantom limbs and smart sensory manipulations, -has shown that the brain’s body image relies heavily on learning via sensory feedback. This study shows the brain capable of reconstructing body image even in the absence of sensory feedback......

Moseley GL, & Brugger P. (2009) Interdependence of movement and anatomy persists when amputees learn a physiologically impossible movement of their phantom limb. Proceedings of the National Academy of Sciences of the United States of America, 106(44), 18798-802. PMID: 19858475   Interdependence of movement and anatomy persists when amputees learn a physiologically impossible movement of their phantom limb.
