Religion is brain poison, and has a twofold effect on the believer's brain:
Further, these false religious beliefs held by the believer each have a twofold impact:
My claim is that ones religion is a major component in the maximum possible mental age a person may attain. If they are a Mormon, Catholic, Greek Orthodox, or Muslim moron, they cannot grow as much as a Jew, as the Jewish religion contains a lesser volume of absurdity than the former three, while it contains a lesser degree of absurdity than the latter one. Therefore, idiot Jews have a greater capacity for attaining higher mental ages than idiots from many other religions. Nondenominational theists are smarter than theists who subscribe to a false belief set, but are still too stupid to entertain alternatives to belief in any god, which detrimentally affects their mental age capacity. Agnostics, who see the reasoning in doubting the existence of god yet are unable to form a simple judgement call that god does not exist, cannot attain the mental ages that atheists can attain.
Now it's time for the converse of modus ponens. No IQ test is capable of being remotely accurate unless it asks you your religious orientation. The proof is in the pudding. As a side note, this plays into why I believe only atheists are worthy of admission to the intelligentsia.
