The document discusses the differences and relationships between UX research and UX design. It proposes that UX exists on a continuum, with UX research on one end and UX/UI design on the other. UX researchers investigate problems systematically through research to understand users, while UX designers create solutions to those problems through design to improve user experiences. The roles of UX professionals may overlap depending on their background and skills. There is often a lack of clarity around UX job titles and responsibilities.
