In Message 24 of this topic, RaSBeY offers the following statistic: "The human sub-group with the highest W value are the 'Plain People,' the Amish and Mennonites, with over 9 children per couple ..." to support his theory that "believing in truth [Christian Creationism] improves one's [reproductive] fitness."
Years ago, I picked up produce from the Plain People of Pennsylvania and Western Maryland. I never once noticed any T.V. antenae, radios, or much else in the way of entertainment other than watching the "birds and the bees" and the occasional Amish Country equivalent of a Hollywood blockbuster hit, "Spring Field Fever," subtitled "Hey, Hezekiah, Come Quick, Beaureguard is Mounting Elsie!" Not to mention that, lacking electricity, a majority of the community hits the sack within a hour past sundown. Add these factors to a strong indocrination in "go forth, multiply, and be plentiful," plus total disregard for birth control, and you have all the makings of huge families regardless of individual sperm counts or female fertility rates.
Come to think of it though, how does this theory of RaSBeY's figure with regard to the gross overpopulation in the Buddhist Orient?
