From the post you refer to:
There are a number of sub-skills, like model-building, having calibrated estimates, and just knowing relevant facts.
Calibrated estimates for future events is the goal of forecasting, and while model-building and knowledge are valuable for this, I think they're valuable in other ways, too. I think another component of good judgement is being able to judge which problems to work on in the first place and how much effort and resources to put into them, falling under instrumental rationality. You need to decide which problems to apply your forecasting skills to, and I don't think this is a forecasting problem.
Also, my understanding is that forecasting is specific to predicting possible future events, and would not include having reasonable views on fundamental research questions, e.g. about consciousness, in physics, in normative ethics, etc..
(I suppose you could try to forecast the answers of experts or even hypothetical experts for fundamental research questions, but experts can be wrong, and this seems like a pretty unusual application and ad hoc way to get at fundamental research questions.)
