He added that "one of the reasons for the formation of PERSEREC was to have somebody study whether there are behavioral or personality indicators which would indicate who is likely to go bad.
Mainly due to a congressional determination that little or no espionage-focused behavioral science existed in the United States, the secretary of defense established the Defense Personnel Security Research and Education Center (PERSEREC) in 1986.
PERSEREC has acted on these study findings and developed a brochure, the aforementioned Counterintelligence Reporting Essentials (CORE).
