L. Ron Hubbard delivered this series of nine lectures to local businessmen detailing the subject of human evaluation. They describe how people can be expected to react under specific circumstances, how to detect those who can be trusted and those who can’t and the methods by which one can ensure success in one’s choices.

“Any time you meet a human being and become associated with him socially, it’d be of some benefit to know by looking at him and talking to him for a couple of minutes, what this individual had in store for you in his friendship with you.” L. Ron Hubbard from the lecture The Purpose of Human Evaluation.

Just subsequent to these lectures in August, the first hardcover editions of Science of Survival were published and copies of the limited manuscript were presented at the First Annual Conference of Hubbard Dianetic Auditors in Wichita, Kansas, in June, 1951.
