Those who wish to work in business, public policy, government, or social science may wish to consider a philosophy, politics and economics (PPE) program. This interdisciplinary field offers students the chance to study how powerful social forces interact with each other.

The PhD is a doctoral degree, specifically called a "doctor of philosophy" degree. This is misleading because PhD holders are not necessarily philosophers (unless they earned their degree in philosophy!). That said, PhD recipients are able to engage in thought experiments, reason about problems, and solve problems in sophisticated ways.
