Another complication in these theist/atheist studies is obvious to anyone who has been stranded on a desert island with a Unitarian and an evangelical Southern Baptist—religion and religiosity are crazy heterogeneous. Which religion? Is someone a lifelong adherent or a recent convert? Is the person’s religiosity mostly about their personal relationship with their deity, with their coreligionists, with humans in general? Is their god all about love or smiting? Do they typically pray alone or in a group? Is their religiosity more about thoughts, emotions, or ritualism?[*],[17]
