According to research based on a study of 374 undergraduate students, there are four different types of drunks. They categorize as: Hemingway, Mary Poppins, Nutty Professor, or Mr. (Ms.) Hyde.
Three Sheets to the Wind. The “Hemingway” group, which comprised almost half the drinkers, were drunks who could handle their alcohol. They didn’t become too unorganized, didn’t start fights, and didn’t change character invariably-just like Ernest Hemingway.
Jeckyl or Hyde? Almost 25% of the group had personality changes, mostly hostile and less responsible. These Hydes were actually half of the women and half of the men.
Up, Up, and Away. Fifteen percent were Mary Poppins, sweet as sugar when getting drunk, and another 12% were Nutty Professors getting goofier and more extroverted.
Besides the kitschy names, the study was conducted to see if addiction and recovery methods might vary and be more helpful depending on the drunk group to which you belong.
