It may take several millions of people to find out that those born in autum have a slightly (in average) different behaviour from those born in spring, but I wouldn't be surprised if that was true.
There is some evidence for health differences between people born in different months. Presumably, early exposure to pollen, as well as the mother's consumption of season-dependent fruits and vegetables, play a role.
