Apparently, if you clicked this..........
As you say, since I clicked this thread, it apparently does
Of course clickbait works every single time! Because one has no way of knowing if a clickbait IS a clickbait!
Some before me pointed out the difference between a clickbait and something that arouses interest...
The difference lies in the fact whether our interest is rewarded or not.
For example if there's a video that says "WATCH THIS!!!!! SCARIEST THING YOU WILL EVER SEE!!!!!" and you DO get quite scared, it is not a clickbait. But if that leads you to something like "Visit the website linked in the description for free torrented horror movies", then it is a clickbait.
So unless we click on something, how do we know it is worth it or not? So clickbait always works, technically speaking.
Now clickbait in other stuff, well, it works quite well too! I mean, half of your skills are assessed by how you start your performance. Throw a flashy opener and your audience is hooked! In fact even in public speaking, a quirky question in the beginning catches their attention, and after that if your magic performance or speech manages to sustain the interest, your bait worked and did good to both, your audience and you. Now those people will be more eager to see you speak or perform.
If you don't render on their expectations positively tho, your bait worked, and did absolutely zero good to your audience (you prolly wasted their time) and did temporary good to you, because they did hang in till the end of your performance, their brains praying you soon do something amazing and satisfy their interest-needs. Next time, they will want to watch you, though they will be less eager. And finally, after being fooled with clickbaits or speech-baits or whatever numerous times, they won't wanna even listen to you.
So you ultimately harm yourself.
So clickbaits work 100% of the time, but their gifts are not really worthy enough to convince anyone to use them.
