genetics of intelligence
gregladen | October 6, 2012No matter how much one may have disagreed with a colleague in life, no matter how much damage one might feel a particular person's work may have done, when that colleague finally dies one says a few good words, pays respect, and puts aside past differences.
But not in this case. I met Jean Philippe Rushton a couple of times but never got to know him as a person. But I do know that he was convinced of the inferiority of Africans compared to, for instance, himself, and spent his entire life improperly manipulating data, sometimes just plain making the data up, to "prove" this. If you look…
dgmacarthur | August 6, 2009CNN reports:
At the Chongqing Children's Palace, experts are hoping to revolutionize child-rearing with the help of science. About 30 children aged 3 to 12 years old and their parents are participating in a new program that uses DNA testing to identify genetic gifts and predict the future.
The test is conducted by the Shanghai Biochip Corporation. Scientists claim a simple saliva swab collects as many as 10,000 cells that enable them to isolate eleven different genes. By taking a closer look at the genetic codes, they say they can extract information about a child's IQ, emotional control,…
dgmacarthur | March 12, 2009I posted a while back on two duelling essays in Nature on the intensely controversial subject of whether scientists should be permitted to study group differences in cognition. Nature now has a series of correspondence on the topic in its latest issue.
Firstly, there are rebuttals from the authors of the two original essays: Steven Rose argues that the debate is dead and that reviving it serves no purpose, while Ceci and Williams argue (substantially more convincingly, in my opinion) that Rose's declaration of these areas of research as invalid is premature.
Some of the other opinions are…
dgmacarthur | February 18, 2009I was surprised by the response to my brief post on the question of whether group (race or gender) differences in intelligence are a valid topic for scientific investigation: not only because of the volume of comments, but also because the ensuing debate was largely civil and on-topic. The post was sparked off by two conflicting essays in the most recent issue of Nature, one by Steven Rose opposing research into such differences, and another by Ceci and Williams arguing that sealing off certain lines of enquiry - however contentious - is dangerous and unscientific.
There's now more on this…
dgmacarthur | February 16, 2009Just in case anyone has missed it, the pair of duelling essays in the latest issue of Nature is well worth a read. The topic is whether there is any justification for scientific exploration of associations between gender or race and intelligence; Stephen Ceci and Wendy M. Williams from Cornell argue the affirmative, while Steven Rose takes up the opposing case.
The debate continues as a lively discussion on Nature Network, which contains many thoughtful comments from both sides.
I find it pretty hard to stomach the notion that any field of scientific enquiry should be completely off the table…
