Gay Germ Hypothesis

JayMan summarizes Greg Cochran’s “Gay Germ” Hypothesis
The case for the gay germ is somewhat indirect, but very strong. Critics often level the charge that there is “no evidence” for Cochran’s hypothesis – i.e., that the offending pathogen has yet to be identified. But the claim that there is “no evidence” isn’t really true; there is in fact plenty of evidence. The facts are certainly consistent with a pathogenic explanation, even if we don’t have the pathogen itself nailed down. But, the most compelling evidence comes in the form of ruling out potential alternative explanations. This itself is a form of evidence. The Sherlock Holmes quote, “when you have eliminated the impossible, whatever remains, however improbable, must be the truth,” is an excellent guiding principle, and is certainly valid here.
This hypothesis seems extremely implausible to me, but I post it anyway to demonstrate the failure of other hypotheses.
