What the researchers said about each group
The Mary Poppins
The Mr Hydes
"Members of this group, much like the dark-sided Mr Hyde, reported a tendency of being particularly less responsible, less intellectual, and more hostile when under the influence of alcohol than they are when they are sober, as well as relative to members of the other groups."
The Nutty Professor
"Nutty Professors change quite dramatically. They are the ones who suddenly gain confidence after imbibing a few."
