I think that someone could write a very reasonable sounding evolutionary psychology article about why the guiding hand of natural selection intervened and stopped cousin marriage due to higher rates of genetic abnormalities. However, in this case they'd be wrong in that the Catholic Church intervened directly and conciously and put a stop to cousin marriage. Finding out that a phenomenon is not due to evolutionary psychology requires careful historical research and that's hard work. Making up evolutionary psychology ideas though takes no time and can make for a great clickbait article.
