I have read a lot of stories, before I didn't care about the subject they were discussing I just wanted to read 

But as someone with a little more knowledge, please do your ing research 

Like I said before, this is fiction but if your doing a hospital au and you diagnosed your  patient with stage 10 cancer then I think it will show you haven't done your research 

if your character have bipolar, but their having  mood swings every hour I think it will show you haven't done your research 

If your doing a debate au, and you don't know  affirmative/negative is then it will show you haven't done your research 

everything I just listed is basic knowledge you would learn if you researched

I'm not a picky person, I will read anything BUT if your story dealing with real life things that have history of research/documentaries /studies

then aleast learn the basics of it, believe me people will appreciate this
