It would be interesting to have some more women plotted against man to see whether women surpassing men at younger ages is a common occurence.
I guess it's not - I searched for players born 2005-2015 and the no.1 girl right now would come 14th among boys.
In another thread, we were discussing Hou Yifan's rise to fame and the possibility of her rising to the very top of the FIDE ratings pool and eventually winning the world championship. So I thought to myself: why not investigate the likelihood of that happening? I went to the FIDE ratings website and downloaded the ratings progress data for Magnus Carlsen, Fabiano Caruana, and Hou Yifan. I then plotted their age on the x-axis, and on the y-axis, their rating in January of the year where they were that age. This is what I obtained:
It's interesting to see how the age progress curves of Magnus Carlsen and Fabiano Caruana, the top two male players, are nearly identical, whereas the curve of Hou Yifan, the top female player, is clearly different. Yifan starts out very strongly, but after about 13 years of age, her progress slows down considerably when compared to her male counterparts.
What conclusions can we draw from this? One possible explanation is that girls are known to mature faster than boys, giving Yifan an edge at a younger age. And one possible outcome is that Yifan most likely will never reach the level of Carlsen or Caruana.
Further conclusions and discussion are welcome.
