Small sample size and confounding variables. In sports that feature drafts and team seasons though I think birth month is more important

So just get pregnant in November/December?
Actually this has been subject of many medical studies. The health of babies is highly correlated with health of mothers, which varies seasonally. I read one such study, but forgot which months or seasons are best for the health of newborn babies!

One example, public health tend to improve after a very cold winter, reason: the cold snap kills more bacteria and other parasites.

Interesting. :unsure:

Another thing that correlates well with cold winters: economic growth.

Healthier people -> more economic activity -> better GNP growth. Economists have known this correlation for a long time.

No coincidence that most wealthy nations are in the northern hemisphere!

I think cold countries are more developed because that's the only way they can survive in the climate. In warmer climates, the people have to do hardly anything to survive in the climate and grow their food ana provide their basic needs. Necessity is the mother of invention.

You think people in India, southern China and elsewhere don't have to do anything to survive? That's plain ridiculous and borderline ****cist!

Some data show August births are associated with the lowest risk of bipolar disorder, and schizophrenics seem most likely to be born in late winter months. So those mid-August months may confer less risk of serious psychiatric illness for future potential champions.

I just realized that Auger-Aliassime (Aug 8th), Tsitsipas (Aug 12th) and Jannik Sinner (Aug 16th) all have birthdays this week. Since they are the three players touted as most likely to win multiple Slams amongst the Next-Gen, there is a good chance that multiple ATGs of the 2020s will have August birthdays also. What a strange coincidence!
 
Not sure if anyone read a book called "Outlier a story of success" but based on the analysis of the first chapter I don't think this is a ****post

I do think the sample is a bit small and it's probably easier to see the pattern for top 100 or top 200 players in the history. If there's indeed a non-uniform distribution of months players were born then it's worth to find out the Matthew Effect behind it
