Intellectual inbreeding

Intellectual inbreeding or academic inbreeding is the practice in academia of a university's hiring its own graduates to be professors. It is generally viewed as insular and unhealthy for academia;[1] it is thought to reduce the possibility of new ideas coming in from outside sources, just as genetic inbreeding reduces the possibility of new genes entering into a population.[2]

According to the Commission on Graduate Education in Economics (COGEE), they recognize it as "a trend for emulation rather than diversification." Academic inbreeding has also been cited as a major problem in the major universities of the People's Republic of China—such as Peking University and Tsinghua University, which have adopted measures in recent years specifically to combat the practice[1][3]—and South Korea.[4] A relevant study[5] also exists that analyzes the issue by considering Russia and Portugal as examples.
