Choosing a major became necessary only after choosing courses became possible.
The college major did not exist before the elective system. When Charles William Eliot introduced course selection at Harvard in the 1870s and 1880s, students gained freedom without a framework. The major emerged as the organizational response, a required concentration of courses in a single discipline that gave structure to the new freedom.1
Harvard formalized the concentration requirement under Eliot's successor, A. Lawrence Lowell, who became president in 1909. Lowell believed that unrestricted electives had produced dilettantes. His solution was to require students to both concentrate in a field and distribute their remaining courses across disciplines.2
The pattern spread. By the mid-twentieth century, virtually every American college required students to declare a major, typically by the end of their sophomore year. The major became the answer to the most consequential question in American higher education: what are you studying?
The National Center for Education Statistics reported that in the 2020-2021 academic year, the most popular bachelor's degree field was business, with over 387,000 degrees conferred, followed by health professions, social sciences, and engineering.3
A 2013 study by the Federal Reserve Bank of New York found that only 27 percent of college graduates were working in a job closely related to their major.4 The system asks eighteen-year-olds to choose a field that will define their credentials for decades, in an economy where most will work in roles that did not exist when they enrolled.
