The recent paper “The Relation Between Intelligence and Religiosity” published in Personality and Social Psychology Review argued that atheists tend to be more intelligent than religious people. The research has frontloaded the study on faulty assumptions and is missing a key factor—a correspondence of worldview to truth.
First and foremost, the research and data gathering is commendable but the assumptions and hidden premises within the study are unsound.
The study associates atheism as non-conformity when stating, “more intelligent people are less likely to conform to religious orthodoxy” (p. 16). This is a category error. If atheism does not conform to the religious majority it still conforms to the non-conformist minority. When this is applied in majority atheist societies, a la Scandinavia, it’s more so dismissed nonchalantly though this criterion is still applied elsewhere in more religious countries (pp. 17, 22). Therefore, non-conformity should not be a measure of intelligence because some societies are religious and others are not; thus, atheism can be either conformist or non-conformist depending on the country, so it can’t be measured that way.
