The most recent World Bank report from 2015 is titled "Mind, Society and Behavior" . It is mainly inspired by endless experimental results from Western Universities and their departments of Psychology and Behavioral Economics. They are craving to donate their advanced knowledge on human behavior to the poor of the world.
And so they identified a surprising problem of the poor: they save too little cash.
Will more rational decision making help them to save the bucks for medicine and their childrens school? May they improve their "mental accounting" by the use of a special World-Bank-iron-box for cash savings?
The poor also borrow too much money. Can we help them to save money by printing a warning of high interest rates on their pay day envelope?
According to the report people have "two systems of thinking", an automatic and a deliberative system. Can we help them by enhancing the deliberative one? And to which one belong the experiments of Behavioral Economics? Hopefully not to the automatic. Sure?
Finally you have to decide yourself how biased this - nevertheless as inspiring as provocative report - is - if you're still in charge of your deliberative system because you're not yet brainwashed by US and UK universities
