The document provides guidance on how to phrase a research problem for a PhD dissertation. It dispels myths that a research problem needs to be earth-shaking and provides examples of seminal works that began from simple questions, such as Margaret Mead's study of cultural stability in Polynesia and Noam Chomsky's inquiry into language acquisition. The document advises that smart research problems ask questions where one has the gut feeling of doing something new. It provides an example of a simple bivariate research question examining whether humor increases class participation and how this could be expanded by considering the influence of sex. Researchers are encouraged to trust that they can find answers worth looking for and to write and discuss simple research problems with partners.
