In their ongoing quest to determine why other people believe in stuff that cannot be demonstrated by logic or cutting open a mouse’s brain, scientists have identified a gene that predisposes people toward religious belief. They’ve also identified a classic problem of deductive reasoning. Citing the World Values Survey, Cambridge economist Robert Rowthorn noted that “adults who attended religious services more than once a week had 2.5 children on average; while those who went once a month had two; and those who never attended had 1.67.” From these statistics, he concluded that “the more devout people are, the more children they are likely to have.” Kombat! Kids: can you spot the flaw in Professor Rowthorn’s reasoning? Probably not, because there are only 1.67 of you for both Combat! readers.
