Still fuzzy? Let’s make it crystal clear: If someone reads only your abstract, they should know the entire story. If someone reads only your introduction, they should know why the story exists. The abstract is for the impatient reader. The introduction is for the engaged reader.
And please, for the love of all that is holy, do not copy and paste your abstract into your introduction. I’ve seen it happen. It’s like wearing your bathrobe to a job interview. Just… no.
