Say I want to know "do people on security.SE report bad practices in their corporate information security to corporate IT". Does the question belong to the main site, meta or shouldn't be asked?
If I understand you correctly, you want to run a yes/no poll. Polling questions are off-topic on main sites but are usually acceptable on meta sites if suitably constructed.
This has been discussed on the main SE Meta here. Essentially, be clear what you are polling for and set a close date.
