What is the traditional approach to comparative politics?

the traditional approach to comparative politics uses case studies of particular regions worldwide. it creates a unique case for each study and therefore there is no generalization of regions, that being one of the downfalls of this approach. the positive side is that the traditional approach creates a specific group of scholars for each particular country/region. although these scholars may be western leaning and possibly infuse biases into their studies, recently they've been more sensitive to each particular case study.
