After reading the article I can tell you that my High School and College educations have done little to improve people's understanding of natural phenomena. I don't know if I agree with the conclusion of the study that there may be a hardwired component to believe in a purpose driven existence or if it is, as was said in the page, that since the majority population of the Earth has this point of view that we are exposed early to parents who are giving us the wrong perspective.
Too much culture. Not enough science.
