Use Your Head
Wells Fargo's Public Relations Department circulated these memos regularly in the late 1940s. There are hundreds of them in the archives. The purpose was to encourage employees to practice self-confidence and keep cool under pressure. The ultimate benefits were better relations among co-workers and better customer service.
What's interesting to me, besides the stunning letterhead, is the ordinary use of psychology at this time. So many of these circulars discuss the mental roots of everyday problems and the psychological methods individuals can employ to neutralize bad tendencies and heighten the positive. Remember, this comes from Public Relations, which exists to construct a message that reassures the public. If there's psychology involved, you can bet it's pretty standard.
In the early 20th century, Freudian psychology 
was transforming away from taboo and scandal to a normal topic of conversation. But it was pretty subjective; the analysis of dreams and pondering the depths of the mind seemed impractical to many. Behaviorism emerged to explain that human action was based on conditioning. Learned behavior had more practical use than experimental stuff of dreams and repression.
Behaviorism was especially popular with business studies. Certain stimuli evoke certain responses. B.F. Skinner and Ivan Pavlov were the stars, demonstrating that animals (including human beings) could be "trained" to behave in certain ways.
The psychology of these memos is especially grounded in action. If people regiment themselves to be cool as a cucumber, tough situations will lessen. If a person strives to finish each task, without going in several directions, they will become more important as well as more productive, etc. Each of us can change our circumstances as well as any laboratory.
Before the Roaring '20s , psychology was the domain of wickedness and crackpots. After World War I, it came into the open. By the late '40s, it was the subject of office circulars helping ordinary people do better work. Over the next generation, psychology would recast the mold on child rearing and women's place in society . A complete evolution of the human potential.
All in one little memo.
