There’s a boy-who-cried-wolf aspect to the modern art of click-bait headline writing. There are certain patterns that emerge, which I’m sure are statistically shown to work. For example, listicles typically no longer use round numbers like 5, 10, 15, 20 — instead, you see things like “17 Gay Celebs Who Pretend to Be Straight on TV” and “17 Facts That Will Forever Change the Way You Look at These Famous People”. (I didn’t make those up, I saw both of those today in the scammy Taboola links beneath an article on TPM.) I’m sure these tricks work, that there’s all sorts of analytics data that shows it — but no trick works forever. People inevitably catch on.
Bolding added by me.
