Should trans women be banned from women’s chess?

The arguments for keeping trans women from participating in women’s sport are well rehearsed. As the former Olympic swimmer Sharron Davies wrote in this magazine in June, the simple truth is that men on average run faster, jump higher and are stronger than women. Their biology gives them irreversible advantages. 

Even the world of chess has been pulled into the debate. Last week, the International Chess Federation banned trans women from participating in women’s matches. The English Chess Federation, on the other hand, refuses to exclude trans women. On first inspection, the decision to ban makes no sense. After all, the usual arguments of unfair physical advantages in women’s games don’t hold water. However, the truth is that differences between men and women go far beyond the physical. Cognitive differences also exist.

Exactly 40 years ago, in Frames of Mind: the Theory of Multiple Intelligences, the psychologist Howard Gardner proposed eight different types of intelligence: musical–rhythmic, visual-spatial, verbal-linguistic, logical-mathematical, bodily-kinesthetic, interpersonal, intrapersonal and naturalistic.
