This might be considered as a further elaboration on my previous question Users acting as authorities, in the sense that, similarly to that question, I want to clarify for myself some existing nowhere written rules that seem to be important for this site.
The question concerns specifically the situation with my answer to the question Does free will require randomness? (although my question here is not just about that answer, it is just an example and I want to know what to do in similar situations). The following text has appeared after it:
Some of the information contained in this post requires additional references. Please edit to add citations to reliable sources that support the assertions made here. Unsourced material may be disputed or deleted.
I gather this is caused by several users having flagged the answer accordingly, so I have at least to take their opinion into account. However in this case I cannot really figure out how to satisfy this requirement - my answer contains a proposed definition of free will and deduces the answer from this definition. Of course I realize that this definition is disputable, and I would be glad to see its wrongs and weaknesses, but what I certainly don't know is whether there is anywhere a similar view of free will that I could cite.
Even more, I have no idea what are criteria for evaluating sources as reliable enough to support my assertions (well, properly speaking it is a definition but ok it may be considered as an assertion); I also don't know whether the above text concerns that definition or the argument following it.
In the help center it is mentioned that
Links to external resources are encouraged but nowhere could I find information about either in which cases is it strictly necessary to accompany assertions with citations to reliable sources supporting them or how to determine which sources are reliable. In particular, I want to ask by which criteria does this answer of mine fall into that category.
Since that answer is quite short I decided just to reproduce it here for convenience
Let us see how concisely this can be answered.
Having free will means nothing more than not knowing yourself what you will do (or will want to do or will try to do) in future. Even if all of your actions are perfectly known beforehand to everybody else but you you still have free will.
