But why should the chance be equal? Nicholas Bernoulli proposed a different null hypothesis: that the sex of a child is determined by chance, with an 18/35 chance of being a boy and 17/35 of being a girl. Bernoulli’s null hypothesis is just as atheistic as Arbuthnot’s, and it fits the data perfectly. If you flip a coin 82 times and get 82 heads, you ought to be thinking, “Something is biased about this coin,” not “God loves heads.”*
