ELI5: Why is it so hard to forget movie spoilers, but so easy to forget more important stuff?
gpt
You don't generally really forget important stuff, you just don't remember it at the correct time. Its rare that if you forgot a meeting, that you have absolutely no clue you should have been in it, after someone reminds you. Once you get triggered, you remember.

Now in case of movie spoilers, you always get triggered to remember it at the worst time. The moment you go see the movie. Giving the impression you never forget a spoiler, but always forget a important meeting.
