That's a conclusion the article came to, but cannot substantiate. for example, Turkey's FR is higher than france despite having stricter family norms, and female workforce participation below average.

For example, many religious people would say policies banning public drag performances are pro-child; while perhaps certain secular people would disagree. Without something more to substantiate that condition, it's difficult to understand what's being measured.
