This is making a strong argument that the more highly classified a piece of information is, the more likely it is to be bullshit, because the fewer people who know the subject matter have had the opportunity to dispute it.

Naturally human nature is to think the opposite, that the most highly protected secrets have been carefully evaluated because they're so important, when the relationship is actually the inverse.

Maybe there should be a maximum period of time that any given information can remain classified, and maybe it should be short.
