A. An intermittent reinforcement schedule
Explanation:
The evolution of social mores in the 1920s is probably one of the most impactful aspect of the Roaring 20s.
While these changes were primarily centered in the urban areas of the United States, they allowed people to begin to move past restrictive Protestant moral values and move to a more open society.
This was done in combination with the explosion of cultural contributions made by African-Americans, centered around the Harlem Renaissance.
This is the kind of concept a utilitarian would agree on. If the result is positive for a large group of people, we should seriously consider doing it.
However, I would like to comment on this concept. In my opinion (and that's what you're asking for) there are situations in which the ends don't justify the means. You can e.g. think about mass-bombings to fight against terrorism. However, the possibility exists that innocent people will be hit, and will die. Therefore, the end don't always justify the means (in my opinion).
