Analysis of an online social microblog, Sina Weibo. Researchers found that "the poor and rich areas were more willing to behave immorally, and the relation between GDP and collective moral motivation was curved. Also, normal people were less ethical when prices increased than when incomes decreased. Ecological construction and the value added by industries which used more farmers and off-farm workers were both correlated with morality. We also found a dark side to science and technological innovation, which harmed collective morality when areas grew richer."
