Why would you choose Stanford’s social sciences department over any other school’s? Especially over schools with a strong reputation in the social sciences (Harvard, Yale, etc.)?
In the social sciences, Stanford, Harvard, and Yale are all on the same level… what it comes down to is personal fit. Some social science students prefer Stanford, others prefer Harvard, others prefer Yale, and still others prefer some other university. There is no “correct” answer, or one best choice for all students.
Visit all with an open mind… you cannot make a wrong decision here.
