Ikram compares my religious experience with that of woman who became a traditional Muslim and moved to Pakistan from America. To my mind Ikram's Skinnerian thesis is undercut by this excerpt from Matt Ridley's Nature via Nurture (page 79):

Take religious fundamentalist. In a recent study Bouchard measured how fundamentalist individuals are by giving them questionnaires about their beliefs. The correlation between the resulting scores for identical twins reared apart is 62 percent; for fraternal twins reared apart it is just 2 percent. Bouchard repeats the excercise with a different questionnaire designed to elicit a broader measure of religiosity and still gets a strong result: 58 percent versus 27 percent....

By the way, the woman contrasted with me (the American turned devout Muslim) mentioned "...loud, crazy, wonderful hijabis...." Weird.
