Here's why:
* The conclusion is for synthesis, not new information: The conclusion should summarize your main points and leave a lasting impression on the reader. It's not the place to introduce new information or arguments.
* Avoid redundancy: You've already cited your sources throughout the body paragraphs. Citing them again in the conclusion can be repetitive and detract from the flow.
* Focus on the bigger picture: The conclusion should focus on the implications of your research and its broader significance, not on specific sources.
However, there are a few exceptions:
* If you're making a direct connection to a specific source in your conclusion: For example, if you're ending with a quote or a key idea from a source, it's appropriate to cite it.
* If your conclusion is directly addressing a specific argument or claim from a source: In this case, you may need to cite the source to ensure clarity and avoid misattribution.
In general, aim for a concise and impactful conclusion that effectively summarizes your research and leaves a lasting impression on the reader.
