Right but isn’t this susceptible to the “is my green your green” qualia problem? The proper conclusion should be that women experience more pain OR are more likely to report their pain as higher. I feel like the former is more likely but how could you tell?

You’re right. I suspect the numbers are very similar for all genders, and most people wouldn’t make any gendered assumptions based on it.

But of those who do make an assumption, I would expect it to favor women due to the way last names are traditionally chosen and how that’s changing culturally in western countries.

Yes, but people are bad at making assumptions that are globally accurate
