In the mid-1990s, John List, who believed that experimental work had provided unique insights into human behavior, began conducting experiments of his own, but in the field rather than in the lab.
 
John has a cheering and wonderful personality, he is insightful and always passionate about life,  what he believes is that life is a rich lab for constructing experiments that he always seek for answers. And I personally believe that the method of his research gives the economic field a complete way of examine the social norms and cultures and other scinarios, and it just takes time for the main streams to realize the value of his research.
