John:
I was thinking more about how the evidence of problems is chewed through an official bureaucracy. Specifically, how much of a barrier is put up to Joe Consumer when his computer flutters? If the regulatory agency makes it hard to register a complaint, or discards complaints for multiple bureaucratic whims, then how do spec writing groups even know there is a problem? For instance, in the USA, no sane person accepts the official data about inflation or unemployment rates.

Yes, this is hard science and no-one in EMC circles denies it. But applying it to emissions or susceptibility that no-one notices enough to complain doesn't make economic sense. -- OOO - Own Opinions Only. With best wishes.
