Altho i think that Dawkins is rong about th degree to wich sientific ideas show virus-like symtms. Surely, ther ar som sientific ideas that spred not primarily becus of their quality. I am thinking of: e.g.: exesiv focus on peer review, exesiv focus on p-valus. But certainly, sience in jenrl is a lot les virus-like than is relijion.
