Hubbard - usually indirectly - desrcibed most of what he was doing to others, before - and sometimes while - he did it to them.
"PR is overt (displayed), Intelligence is covert," Hubbard wrote in PR Series #7 (And Hubbard's "Scientology ['dirty tricks'] Intelligence tech," by the time the PR Series was being written, was already mostly complete, and in full use. And even though the average Scientologist didn't know such a "tech" existed, he/she probably would have thought it justified. However, these same Scientologists would have been surprised to learn that this "tech" was also being used on them.)
And, in Scientology, "PR" is, ultimately, subordinate to "Intelligence," just as "Love" or "ARC" is subordinate to "Will" or "KRC."
That the "good stuff" of Scientology was placed, by Hubbard, in the subordinate category of "PR" is almost impossible for most well-meaning "tech people" to digest.
The historical record, going back at least to 1938, indicates that Hubbard always had a hidden agenda, or "real goal," of self-aggrandizement, while using as a disguise, "philosophy," "self-improvement," "a better world," etc.
That the "disguise" had some redeeming characteristics, IMO, makes it all the more confusing.
