How to "Prove" That Basketball-Players are Born that Way
Suppose you are motivated to demonstratefor political reasons--that there is a basketball gene that makes people grow up to be basketball players. You would use the same methods that have been used with homosexuality: (1) twin studies; (2) brain dissections; (3) gene "linkage" studies.
The basic idea in twin studies is to show that the more genetically similar two people are, the more likely it is that they will share the trait you are studying.
So you identify groups of twins in which at least one is a basketball player. You will probably find that if one identical twin is a basketball player, his twin brother is statistically more likely be one, too. You would need to create groups of different kinds of pairs to make further comparisons--one set of identical twin pairs, one set of nonidentical twin pairs, one set of sibling pairs, etc.
Using the "concordance rate" (the percentage of pairs in which both twins are basketball players, or both are not), you would calculate a "heritability" rate. The concordance rate would be quite high--just as in the concordance rate for homosexuality.
Then, you announce to the reporter from Sports Illustrated: "Our research demonstrates that basketball playing is strongly heritable." (And you would be right. It would be "heritable"--but not directly inherited. Few readers would be aware of the distinction, however.)
Soon after, the article appears. It says:
"...New research shows that basketball playing is probably inherited. Basketball players are apparently 'born that way!' A number of outside researchers examined the work and found it substantially accurate and wellperformed..."
