Reply to comment by enny_el in [OC] Birth months of FIFA World Cup players. The top three are January, February and March, possibly due to the "Relative age effect" by desfirsit

>surely this can't still be giving intentionally-held-back kids an edge once they are older?

That's the weird thing: It does. Being the oldest/tallest/strongest/smartest kid in your cohort means coaches give you more game time, or you gain more academic confidence and skill among your peers in early grades. And it snowballs from there.

I just find it hard to believe that that applies universally across countries and cultures and hemispheres and school systems and everything. But maybe I just don't want to believe it because it means I already screwed everything up for my September-born kid! Doomed from birth, poor thing!

Which month is the "right" month definitely changes by culture, but the premise that being the oldest in your childhood cohort confers an early advantage seems to hold across multiple countries.

If it makes you feel any better, the magnitude of the advantage conferred isn't huge. I'm a September baby, was almost always the youngest in my class, and (at the risk of bragging) I'm objectively successful. I was never great at sports, but being several inches below average is probably the culprit. :)
