Field experiment是不能让被试太清楚你要干啥的,这是这类研究的共性。我有一次兴高采烈地跟我一个做HR ...
My apologies, my misunderstanding about field experiment.
What actually annoyed me is the 'discrimination' in the research.
I understand 'discrimination' can be a research topic, nevertheless I have no idea whether it is OK to show 'discrimination' which hurt others in research.
At least, I am hurt by the discussion on Tianya. In my view, any kind of discrimination is unacceptable, although the purpose is to make contribution to human's knowledge.
