### please step away from the calculator

More nonsense statistics hoping to prove something useless. My problem with this comes in the bar graph... which displays what appears to be a shocking difference in IQ between those who are religious and those who are not.

... but then I think... why is the y-axis for this graph chosen at '96-104'?

... well, it captures the data I guess... and the claimed error bars...

but why not start at '97'? that would make the difference look even more magnified in the graph.

From a brief look on our internets... one standard deviation in IQ is approximated by about 16 IQ points.... so now we need to envision this data plotted on a y-axis of *at least* 80-120 to get any sense of the scope of differentiation the data is actually meant to convey. Now place normal distributions on top of each data point with a standard deviation of 16... and bang, any differentiation is completely washed out in any reasonably scientific data analysis.

"there are lies... damn lies... and then statistics..." as they say.

UPDATE:

Sorry... I just couldn't help it...
