Well, as it turns out, atheists have one more thing to be smug about.
(Where is your god now?!)
Religious people are less intelligent than non-believers, according to a new review of 63 scientific studies stretching back over decades.
Previous studies have tended to assume that intelligent people simply “know better”, the researchers write – but the reasons may be more complex.
The studies used in Zuckerman’s paper included a life-long analysis of the beliefs of a group of 1,500 gifted children – those with IQs over 135 – in a study which began in 1921 and continues today.
Even at 75 to 91 years of age, the children from Lewis Terman’s study scored lower for religiosity than the general population – contrary to the widely held belief that people turn to God as they age. The researchers noted that data was lacking about religious attitudes in old age and say, “Additional research is needed to resolve this issue.”
As early as 1958, Michael Argyle concluded, “Although intelligent children grasp religious concepts earlier, they are also the first to doubt the truth of religion, and intelligent students are much less likely to accept orthodox beliefs, and rather less likely to have pro-religious attitudes.”
A 1916 study quoted in Zuckerman’s paper (Leuba) found that, “58% of randomly selected scientists in the United States expressed disbelief in, or doubt regarding the existence of God; this proportion rose to nearly 70% for the most eminent scientists.”
The paper, published in the academic journal Personality and Social Psychology Review, said “Most extant explanations (of a negative relation) share one central theme—the premise that religious beliefs are irrational, not anchored in science, not testable and, therefore, unappealing to intelligent people who “know better.”
