I get a paywall through the web link (from UK).

However right-clicking the main link and opening in private browsing seems to work.

This gets asked and answered so often than perhaps HN should add an instruction to the "web" link that tells you to open it in a new private/incognito window.

I noticed the same thing, though it looks like the DOI works correctly now. There must have been some delay in the online publication going live.

I don't know if chess is a very good example since in that case there was a woman who was very clearly an outlier (as is Rousey) but able to compete against men, and reached a top ten ranking (Judit Polgár).

I am saying women do way worse on average. Judith Polgar did well but was nowhere close to be say world championship contender and she received more training as a child than about any man in history at that time. Judith was also the only Polgar sister who reach world class strength. These days Hou Yifan is close to world class strength and it can be argued that her level of play suffered because of politics (it's important for China that she plays in women team and playing vs weak competition isn't the best for the development). Maybe she had top 10 potential as well.

It's definitely less disadvantage in chess than it is in MMA but it seems the effect is still there.

It'd be really nice if articles like this actually linked to the website for what they're talking about.

It's http://www.fundamentalphysicsprize.org for the record.
