One-child policy shaping a nervous nation: study

CHINESE children born under the one-child policy are less trusting, less competitive and more risk-averse than those born previously, according to Australian research.

Psychological experiments conducted with 421 people from birth cohorts before and after introduction of the policy in 1979 showed those with no siblings were more nervous, more sensitive and more pessimistic.
