Why is that problematic? Doesn't the fact that is has very exceptions make it a rule? This basically means there is a wide set of confouding factors at play...

It’s problematic because it suggests we don’t really understand why low fertility happens, or what to do about it.

Vast amounts of money might be wasted by governments in Poland, Hungary & elsewhere on fertility boosting programs that likely won’t work.

And academically, our dataset of countries is relatively small to begin with, so it only takes a few exceptions to break any statistical confidence.
