Does this mean that people accept religious beliefs because they are dimwitted? Not necessarily. Atheists are probably more intelligent than religious people because they benefit from many social conditions that happen to be correlated with loss of religious belief. When one looks at this phenomenon from the point of view of comparisons between countries, it is not hard to figure out possible reasons that more intelligent countries have more atheists and that more intelligent states in the U.S. also have more nonbelievers. Here are some. Highly religious countries: â¢Are poorer. â¢Are less urbanized. â¢Have lower levels of education. â¢Have less exposure to electronic media that increase intelligence. â¢Experience a heavier load of infectious diseases that impair brain function. â¢Suffer more from low birth weights. â¢Have worse child nutrition. â¢Do a poor job of controlling environmental pollutants such as lead that reduce IQ.
