OTOH, https://www.newscientist.com/article/2509261-high-achieving-...

I always think of the Little League World Series when I read about stuff like this; these kids are often peaking early and so rarely make it to the highest levels as an adult. This is either because they quit advancing at the same rate or they've destroyed their bodies before they get to high school.

I think there's been like a handful LLWS winners who have done anything in the MLB and even fewer who have reached the top of pros.

Natural ability (physical or mental) is not strongly correlated with the personality traits that enable a person to "perform", "succeed", or "achieve" in society the way it is structured. In fact, they may be inversely correlated (consider how often people in leadership positions are not apparently exceptional).

Tiger woods. I can't think of any tennis player who has been in the top 100 for the past few decades who didn't commit to it totally as a young child. Start tennis at 10? Too old. Swimmers. Has anyone stumbled into sporting greatness from being outside the top 5%? Or 1% when they hit adulthood?

So what is being said? A huge amount of elite success is in the hardware, i.e. the body &/or brain. These go through rather large changes between ages 10 an 18. Puberty. This shakes up the ordering among those who showed enough promise to have already committed to becoming elite.

What am I missing here? Seems like this research is nothing more than "Kids change through puberty, the nature and sizes of the changes are a bit of a lottery for each kid." Much like the the genetic factors are also a lottery so you can't reliably predict who is going to be great from the results of their parents. (But if your parents are both 5ft, the NBA seems an unlikely destination for you).

The headline could be rephrased as "Elite performers rarely become elite performers", and it would mean the same thing. Maybe it's better to say "Elite performers are rarely elite performers for their whole lives"

> Around 90% of superstar adults had not been superstars as children, while only 10% of top-level kids had gone on to become exceptional adults (see chart 1). It is not just that exceptional performance in childhood did not predict exceptional performance as an adult. The two were actually negatively correlated, says Dr Güllich.

Even if "only 10%" of elite kids go on to become elite adults, 10% is orders of magnitude larger than the base percentage of adults who are elite athletes, musicians, etc. This doesn't sound "uncorrelated" to me so much as "not as strongly correlated as one might expect."
