just ask

It's difficult when the creators are dead, or otherwise unaccessible (like busy hedge fundies). The next best thing are students who were mentored under the creator of the paradigm and are considered experts, but then the same check has to be applied to them on whether or not the ideas can be discussed. Overall I like the approach, it might still be possible to find journals, biographies or interviews with the originator of the viewpoint, as these are likely to contain some form of inquiry.
