We close questions as duplicates when the code is too similar (or pretty much identical) to a previous question by the same asker.
When marking a question as a duplicate the following text is shown:
This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.
I feel that this text is a misguide. From reading this text, it can be interpreted as "Oh, my previous question got only one answer, and it didn't help me as much as I wanted to, then I will post the same code again in a new question (but wait, isn't that exactly what I just did?)".
The text does not provide the suggestion of change your code to include suggestions from the answers you have received. It also does not mention that you can add a bounty to your previous question, or that you can share your question in chat, on Twitter, etc.
I suggest that we should change this text if possible. How can we make this text work better for Code Review?
