Are the techniques presented on this site powerful enough to allow interested non-experts to do a better job in evaluating a complicated issue than expert analysts?

No, the experts will do a better job. Actually, I had idealistically envisioned that experts would dominate the discussion while non-experts observed, occasionally bringing forth ideas from their field of expertise.

However, with a smaller group with no critical mass of experts, we may still make some headway in cases when:

(a) It is unclear how to apply an expert opinion. This often happens when the application spans or escapes fields of expertise.

(b) The experts don't have a consensus. RPOV can figure out how to make decisions that minimize risk when the experts have incomplete or conflicting solutions/predictions.

Other examples? Particularly, any specific examples when RPOV among non-experts would lead to better solutions than what one non-expert might come up with individually?
