A striking biographical fact about NSA whistleblower Edward Snowden:

By his own admission, he was not a stellar student. In order to get
the credits necessary to obtain a high school diploma, he attended a
community college in Maryland, studying computing, but never completed
the coursework. (He later obtained his GED.)…

After that, he got
his first job in an NSA facility, working as a security guard for one
of the agency’s covert facilities at the University of Maryland. From
there, he went to the CIA, where he worked on IT security. His
understanding of the internet and his talent for computer programming
enabled him to rise fairly quickly for someone who lacked even a high
school diploma.

I’ve repeatedly argued (here, here, and here for starters) that education signals conformity.  Question: Is there any tendency for whistleblowers to have atypically low credentials?

Note: While prudent organizations put a high premium on conformity, wise moralists do not.
