More than half of the explanation for the administrative bloat since 1976 was blamed on factors that did not change much since the 1960s - with the notable exception of foreign sanctions, which were much worse due to the cold war. Also blamed were IRBs, which have been a requirement since 1974: https://en.wikipedia.org/wiki/Human_subject_research_legisla...

The "accurate responses" were non-explanations. Like blaming being three hours late on a single red light.
