From Tim Moore, University of Hong Kong
John Drake states that the view that men are more promiscuous than women
involves a physical impossibility
(22 April, p 50).
It seems to me that what it involves is rather a logical impossibility. If degrees of
promiscuity are measured by the number of sexual relations with a person of the opposite
sex (in any heterosexual population with equal numbers of males and females), we can
prove that the net promiscuity of each sex must be identical.
We can also prove that if there are more males than females, the net
promiscuity of males must be lower than the net promiscuity of females.
