People SAY they will, but don't. They just worked up and then come back anyway out of curiosity. It's the sunk cost fallacy. When people drop things it's usually after long, protracted issues, not sudden twists
I still can't find the retention statistics you are referring to.
Or if you are just claiming without proof, I should point out that I have dropped tons of stories as a result of a bad chapter showing the story is not what was promised (and instead is something I am absolutely tired of), and cliffhangers won't make me curious enough to return unless I get the next chapter absolutely shoved into my face (and often not even then). Sure, I don't generally post about it, but I also know that others
have posted about doing the same on some of those chapters. So if anything the numbers would be
greater than the ppl who made a comment.
...But you wouldn't have asserted it so strongly if you didn't have retention statistics on this chapter backing you up, so the above is mostly irrelevant.
