This site is supposed to be about the following:
Specific issues with governments, policies and political processes
Real problems or questions that you’ve encountered
And not about the following:
Anything not directly related to governments, policies and political processes
Questions that are primarily opinion-based
Questions with too many possible answers or that would require an extremely long answer
However, it is impossible to entirely remove bias from how questions are asked. Likewise in answering, voting, commenting, and moderating. Every action has the possibility of some bias behind it. Add the word "Politics" into the mix, and it is inevitable that even within the accepted scope of "specific issues with policies" with lead to a discussion of opinions. We must all aim to be responsible in how we do our actions, but there is no guarantee that is the case. Not everyone reads meta, and there is no presence like academic or scientific rigor elsewhere that exists here. Only the collective actions of the community and the Stack Exchange company.
Because of this reality, it is worth asking the following question "Does Politics Stack Exchange, as a whole, have a bias"?
Furthermore, in answering that question, some sort of quantification or measurement must be taken (for the answer to the above question to elicit fact). But whoever partakes of this measurement or task is almost certainly part of this community, and thus the collective bias. Thus I ask the following corollary as well: "How is it possible to objectively quantify this bias, if we, in this community, compose part of it?"
