What parent wants their child to turn out STUPID ? THE best way to stay Atheists since birth is for parents to teach critical thinking ESPECIALLY ABOUT ALL religions.....xmas, easter and thanksgivings are vmbr .....bribery torture and talking to nothing overlooking a feast table...too many holydays too much religion too stupid to survive in a violent faiths dominated world

Its an interesting study but a limitation is the representative samples by region.

The weighting is very much toward USA with hardly any representation from Africa, Aus/NZ and Middle East. See the supplementary table 3

For me the important take away from the results in the study is the learned behavioural bias which informs the individual to use intuitive rather than logical responses when the two are in conflict, a classic religious/indoctrination strategy.
