This seems correct to me, i.e. the current title here is clickbait.

From the paper:

"The results of the present study did not support my hypothesis that intelligence should be negatively associated with childlessness."

In fairness, the somewhat confusing verbiage here is from I assume a Norwegian non-native English speaker.

To their defense, a lot of academic papers even from native English speakers tend to have barely readable convoluted wording here and there. Either for the purpose of making it sound more complicated or to pad the length of the paper, I have no idea. But it is something I have been consciously noticing since a while ago.

Ah, that makes perfect sense to me (both your wording and the conclusion itself), so thank you.
