The Science section of the Times often has useful articles, but whether it is in the news or the science section, they continue to repeat and embellish a mythological understanding of science that is enough to make one wish that the repetition of certain ideas should be made illegal.
In an article by Benedict Carey, Some Politics May Be Etched in the Genes, a number of remarkably inane and inaccurate comments are made. (Hat tip: Pejmanesque)
It starts off with a relatively meaningless and innocuous statement:
Political scientists have long held that people's upbringing and experience determine their political views. A child raised on peace protests and Bush-loathing generally tracks left as an adult, unless derailed by some powerful life experience. One reared on tax protests and a hatred of Kennedys usually lists to the right.
And goes down hill from there:
But on the basis of a new study, a team of political scientists is arguing that people's gut-level reaction to issues like the death penalty, taxes and abortion is strongly influenced by genetic inheritance. The new research builds on a series of studies that indicate that people's general approach to social issues - more conservative or more progressive - is influenced by genes.
There is some superficial description of the study's methodology:
From an extensive battery of surveys on personality traits, religious beliefs and other psychological factors, the researchers selected 28 questions most relevant to political behavior. The questions asked people "to please indicate whether or not you agree with each topic," or are uncertain on issues like property taxes, capitalism, unions and X-rated movies. Most of the twins had a mixture of conservative and progressive views. But over all, they leaned slightly one way or the other.
The researchers then compared dizygotic or fraternal twins, who, like any biological siblings, share 50 percent of their genes, with monozygotic, or identical, twins, who share 100 percent of their genes.
Calculating how often identical twins agree on an issue and subtracting the rate at which fraternal twins agree on the same item provides a rough measure of genes' influence on that attitude. A shared family environment for twins reared together is assumed.
I do not expect people without some minimal knowledge of science and the scientific method to be able to adequately understand how science works. Furthermore, I don't expect anyone without a minimal knowledge of genetics to understand how genes express themselves. But I did once expect (and we all should expect) a reporter for our most prominent daily newspaper, the "paper of record", to have a minimum level of competency before going off and writing on a subject like genetics. This study, as described, is so nonsensical as to be worse than a parody.
Where do I start?
