Re:People who are blind from birth never develop schizophrenia

Not the original commenter, but the math is (making some implicit, but arguably reasonable assumptions):
Probability that someone in the population has schizophrenia = (1870/500000) = 0.00374
Probability that someone does NOT have schizophrenia = (1 - 0.00374)
Then if we assume that blind people have the same rate of schizophrenia as the population,
Probability that 66 blind people ALL don't have schizophrenia = (1 - 0.00374)^66 = 0.78

The sad thing is that IF — by chance — one of those 66 had schizophrenia, the headline would undoubtedly read “Blind children are FOUR TIMES more likely to develop Schizophrenia!”
