Many years ago a brilliant Singaporean scholar, who specialized in organizational psychology, told me that he had discovered that healthy, good looking, well treated and well paid employees were more likely to be happy with their employer than workers who were poorly treated and poorly paid.

Roughly at the same time a brilliant Chinese economist told that she had proved, mathemathically, several historical facts including the fact that a urban population had a higher turnout in the first democratic elections than the population in urban areas.

In this line of seminal contributions to advancing our understanding of crucial social phenomena, the press now reports that malnutrition is a cause of poor child health.

It’s thanks to such find discoveries that social sciences have earned their well deserved reputation.
