Yesterday, I asked this question on the Biology SE. Shortly after posting, I received a comment saying that a close vote has been posted and stating the ways in which I can improve the post. The main points stated were:
- I asked multiple questions in my post
- I did not include relevant links, sources, etc to my post
The reason I included multiple questions was because I did not want to post too many related questions in the same network at the same time. I had already posted a question regarding color-blindness, and I thought that since pretty much the same people were answering my questions, they might find it easier to just have everything in one question, especially since they were related questions.
I did not include links because this is not a very well-researched topic, and I wasn't able to find any links. Like I mentioned in my post, I did read about this somewhere, but I wasn't able to find the link again when I tried to. I usually complement my question with links, but this was an exception when I did not have any.
Although I have edited the post and added more relevant links (and also removed the follow-up question), I would like advice on what I should do in the future for such a situation. If I honestly can't find anything, how am I supposed to quote relevant sources? I know that such a restriction exists to uphold the quality of the site, but there are times when I won't be able to include any relevant links.
