Quote of the Day: Gene Selection: Society is built on mutually beneficial co-operation

At his blog, businessman, science journalist and author Matt Ridley discusses the political implication of Gene Selection versus Group Selection:

“Group selection” has always been portrayed as a more politically correct idea, implying that there is an evolutionary tendency to general altruism in people. Gene selection has generally seemed to be more of a right-wing idea, in which individuals are at the mercy of the harsh calculus of the genes.

Actually, this folk understanding is about as misleading as it can be. Society is not built on one-sided altruism but on mutually beneficial co-operation.

Nearly all the kind things people do in the world are done in the name of enlightened self-interest. Think of the people who sold you coffee, drove your train, even wrote your newspaper today. They were paid to do so but they did things for you (and you for them). Likewise, gene selection clearly drives the evolution of a co-operative instinct in the human breast, and not just towards close kin.

It can even drive a tendency to defend fellow members of the group if the survival of the group helps to perpetuate the genes. But group selection is a theory of competition between groups, and that is generally known by another name in human affairs. We call it war. If group selection were to work properly, war would mean the total annihilation of the enemy by the victorious group.

From New Scientist: The Ten Commandments of Race and Genes

Some interesting science trivia on race and genetics. The message is that cognitive biases also apply to this field.

From New Scientist, the 10 guiding principles or the “ten commandments” for geneticists in dealing with issues of race, genetics and medicine.

1. All races are created equal

No genetic data has ever shown that one group of people is inherently superior to another. Equality is a moral value central to the idea of human rights; discrimination against any group should never be tolerated.

2. An Argentinian and an Australian are more likely to have differences in their DNA than two Argentinians

Groups of human beings have moved around throughout history. Those that share the same culture, language or location tend to have different genetic variations than other groups. This is becoming less true, though, as populations mix.

3. A person's history isn't written only in his or her genes

Everyone's genetic material carries a useful, though incomplete, map of his or her ancestors' travels. Studies looking for health disparities between individuals shouldn't rely solely on this identity. They should also consider a person's cultural background.

4: Members of the same race may have different underlying genetics

Social definitions of what it means to be "Hispanic" or "black" have changed over time. People who claim the same race may actually have very different genetic histories.

5. Both nature and nurture play important parts in our behaviors and abilities

Trying to use genetic differences between groups to show differences in intelligence, violent behaviors or the ability to throw a ball is an oversimplification of much more complicated interactions between genetics and environment.

6. Researchers should be careful about using racial groups when designing experiments

When scientists decide to divide their subjects into groups based on ethnicity, they need to be clear about why and how these divisions are made to avoid contributing to stereotypes.

7. Medicine should focus on the individual, not the race

Although some diseases are connected to genetic markers, these markers tend to be found in many different racial groups. Overemphasising genetics may promote racist views or focus attention on a group when it should be on the individual.

8. The study of genetics requires cooperation between experts in many different fields

Human disease is the product of a mishmash of factors: genetic, cultural, economic and behavioral. Interdisciplinary efforts that involve the social sciences are more likely to be successful.

9. Oversimplified science feeds popular misconceptions

Policy makers should be careful about simplifying and politicising scientific data. When presenting science to the public, the media should address the limitations of race-related research.

10. Genetics 101 should include a history of racism

Any high school or college student learning about genetics should also learn about misguided attempts in the past to use science to justify racism. New textbooks should be developed for this purpose.

The Stanford group didn't always agree when coming up with these ideas. Predictably enough, the biomedical scientists tended to think of race in neutral, clinical terms; the social scientists and scholars of the humanities argued that concepts of race cannot be washed clean of their cultural and historical legacies.

But both groups, according to the letter, recognise the power of the gene in the public imagination and the historical dangers of its misrepresentation as deterministic and immutable.
