Rethink family planning policy

China's family planning policy has produced a generation of untrusting and over-sensitive "little emperors", a new research by the University of Melbourne has found.

The study shows that individuals who grew up as single children are significantly less trusting, less trustworthy, more risk-averse, less competitive, more pessimistic and less conscientious, according to Nisvan Erkal, associate professor at the University of Melbourne's department of economics.
