Here's a slightly more precise version of my previous proposal for testing Christian Science. Take the practitioners in the January, 1910 edition of "The Christian Science Journal." What percentage of them are alive now? If less than one percent, Christian Science fails. If greater than 50%, Christian Science succeeds. One to fifty percent is the No Man's Land, and should not occur. If the result occurs in that region, it's a very interesting situation, demanding new investigation.
