Data independence

September 27, 2007 Leave a comment Go to comments

I left a message on Professor Phil Rosenzweig’s website (http://www.the-halo-effect.com) to appreciate how I like his book (The Half Effect) and inquiries about the book that I posted here.

Professor Rosenzweig kindly replied me and said  the most important issue is about data independence whether it’s qualitative or quantitative.

As we know, differences perceptions and memories in informant, it’s really difficult to maintain the data independence for doing research works, especially those done by qualitative approaches. However, it does not mean the public data can warrant the data independence. For example, Enron did show good performance in various criteria before going into collapse.

Therefore, the question in academic is how to sustain and maintain data independence without losing rich information we may learn from informants and public data.
