Thanks Mick for your comments above.
I haven't read the True Believer so I did a google search and found this:
http://en.wikipedia.org/wiki/The_True_Believer
In reading the write-up for the book The True Believer, the first summary point mentions :
"Hoffer argues that mass movements begin with a widespread "desire for change" from discontented people who place their
locus of control outside their power and who also have no confidence in existing culture or traditions."
That is interesting in that "desire for change" is one of the hooks in scientology. And also the people who place their "locus of control" outside their power, that is basically dianetics where hubbard says in a nutshell that engrams are what was done to you.
Both these items appealed to me big time when I first started.
When I did the google search above I also saw this:

Now that write-up is absoluting amazing.
"Some in their congregation still believed that Raoul was genuine even after he openly admitted that he was a fake. Keene wrote "I knew how easy it was to make people believe a lie,
but I didn't expect the same people, confronted with the lie, would choose it over the truth. ... No amount of logic can shatter a faith consciously based on a lie."
OMG. This is exactly what is happening in scientology. People just won't believe there is no such thing as a "clear" or "OT" even when confronted with the truth.
