What is the community's approach to 'Test My Theory' style questions?

It is worth considering that this style of question often garners opinionated discussion rather than factual response, which seems discouraged according to the rules of the site.

Should the permissibility of the question depend on whether the OP shows that they have done research on their topic before consulting this domain?

Is it recommended that these theories show that they are supported by philosophical canon, or are is it expected that OPs may not have sufficient background to do so?

If more relevant concerns are thought of, please add them in the comments.

I intend to impart no bias on this question; my intentions are to understanding what the community's approach to this issue is.
