By targeting a definable probabilistic model, it is possible for all research studies to be consistently grounded.   Certainly, problems will arise in extremely low incidence studies where there are an insufficiency of profiled respondents but the idea is clear.   If POD gets big enough, the research community will able to tell its clients what their sampling frame represents.

As panels provide us with profiled individuals we will be able to draw samples from their contributions to check for the consistency of the panels themselves.   We do it now but are dependent on the panel to provide us with samples.  In the future we will be able to draw random samples that are quota controlled from POD and generate our usual consistency analysis.
