But knowing the research involved in Comparative Politics, undoubtedly Empirical Approach is not only the most suitable, but also absolutely necessary.
Comparative politics is considered to be an area of intense and continuous research, trying to keep up with the world politics, understanding intricacies of international relationships and foreign policies and diplomacies either leading to events or resulting from them.
"The study of comparative politics, like the study of the other sciences, has had a logic of its own, a developmental pattern that combined specific questions about the various nations and peoples in the world, specific data, and specific problems, all within a learning process that has taken a specific direction and reached a working synthesis of its own past," Lane (1997, p.2).
It is important as it is also the study of different cultures, ideologies, nations and diverse thinking processes. This is different from political correctness and it does not expect all administrations and policies of all countries to be uniform. Actually it celebrates the diversity, accepts peculiarities and the unknown and hence, more natural and less overbearing. It does not revel in terms like barbarians or foreigners.
It involves comparing countries, their problems, economic development and democracy, monarchies, military and autocratic rules, violent political dissent and social revolutions, pure and hybrid regimes, predicting the democracies, non-violent political dissents and transitions to democracy, performances of such democracies, design of institutions, new challenges, and in the end, there is a process to compare the comparisons. It also involves in a linear relationship between economic development and democracies, explanations to democratic institutional performances, positive and negative relationships between ideologies and their institutions.
Hard facts concerning history, economics, sociology and politics are found through empirism. It emphasizes the collection of empirical data and the rigorous testing of theoretical proposition against this data.
"Empiricism: models or theory were non-existent in traditional comparative politics, at least at the level of intention and recognition. Concepts were often employed with little methodological discussion as to their definition and measurement," Bill and Hardgrave in Lane and Ersson (1994, p.2).
As unanimity cannot be established in world governments, the interests and attitudes of influential groups that are running the administration in various countries have to be studied under 'Comparative Government' and for this process, there is no replacement of empirical approach. In studies concerning politics, empirical method provides all answers and offers insights to understand diversity. Aristotle, in his days, being disturbed by the infighting and instability of States around him, causing havoc, had studied those governments empirically, by classifying them into three groups and then, by subdividing them into further five groups, according to their wellbeing and wealth, legitimacy, monarchy and tyranny. This is exactly what the present day political scientist does by way of analysing through empirical methods, collecting data, enhancing or condensing the collected evidences and classifying them under various groups, according to their ideologies, forms, institutions, political religions, cultures, agendas and national
