That is Bob Garfield from On The Media in an interview
with Johann Bollen on sentiment analysis. Clearly, Mr. Garfield does not understand the purpose of qualitative research. Any textbook on scientific research methods will tell you that quantitative research focuses on the power of generalization and statistical representation, while qualitative research enables explanation, understanding, and theoretical representation. Both, however, are socially embedded practices and, therefore, can be logical or irrational, sophisticated or simple, large or small (in terms of data, scale, time, labor), as well as sloppy or rigorous.
