The description of this proposal reads like it is about the process of making good judgements, and people are expected to ask questions about decision making processes. However the actual questions all read like general purpose questions, not connected by any area of expertise, implying that answerers use good judgement in answering the questions.
The likely problems with this are:
- The questions are likely to duplicate other sites. All Stack Exchange answers are expected to use good judgement, good decision making, and good evidence. Therefore (for example) a history question on this site is not any different from a question on the history site
- There is no expert community for this site. A question on history requires a history expert. A question on economics requires an economics expert. A question on cybersecurity requires a cybersecurity expert. There is no common thread to the questions.
- Forecasts by their very nature tend to be the kind of thing that doesn't have a definitive answer. SE questions are expected to at least potentially have a definitive answer.
- Stack Exchange has never been in favour of catch-all proposals, and this reads rather like one.
If I have misstated the situation, please explain in an answer.
