The thing to know here is the bayes factor. That’s the true positive rate divided by the false positive rate.

This removes any advantage a property gets from being more common.

[Edited to note: Yep. YouTube is dominant as the popular publisher in this review, and truncates headlines at 66 chars - that's what this article observes]
