There are also other reasons birth month could be related to psychiatric disease that sound more pseudoscience-y at first. There's good reason to believe that infection at the wrong time of pregnancy can increase risk of Schizophrenia for example, meaning that the alignment of cold and flu season could affect disease rates by birth month.

I agree the comment was probably just being sarcastic, but I think it's worth noting that there could be a more biological component to an effect like this, doesn't need to be a societal environment/diagnosis rate thing to be plausible.

It's interesting reading about a lot of pseudoscience as you go through scientific training, because obviously you have an immediate negative reaction to it. But I've started to notice that more often than not there is some underlying grain of truth that is taken to an extreme and/or given a ridiculous explanation. This in turn dampens real research on the potentially interesting line of questioning.
