Playing with the Numbers
By Dan Olson | May 4, 2005To the Editor: I was surprised to hear the statistic cited in Jen Garfinkel's article ("Grabowski lectures on sexuality, Catholic doctrine," May 2) that "family planning" was 98 percent effective against unwanted pregnancies, compared with 92 percent for oral contraceptives and 80 percent for condoms. If one examines the current publication from the World Health Organization about the failure rates of various birth control methods, one can see how Grabowski manipulates his numbers.
