I’m not a professional academician by any means. I’m just a medical student trying to write a paper in my spare time.
I don’t have an excellent grasp of the literature in this field. A lot of the information I’m learning comes from a single excellent review article/book chapter.
Here lies my question. This book chapter will say, e.g., ”such and such ”. Do I just cite the book chapter when I describe such and such in my background? I think not; I should probably cite , , or both.
So, the real question: is it OK/acceptable/ethical to just believe that  and  contain such and such; and just cite them without actually reading the papers? To be able to do this would save me quite a bit of time.
