Weber offers an excellent description and a user's guide to the technique of abstraction and idealization that also directly applies to the conceptualizing strategy of mainstream economics that is on a completely different track with its law-seeking efforts.
Critics of ideal type include proponents of the normal type theory.
For Weber, the conduct of social science depends upon the construction of abstract, hypothetical concepts.
The "ideal type" is therefore a subjective element in social theory and research, and one of the subjective elements distinguishing sociology from natural science.
This does not mean, however, that objectivity, limited as it is, can be gained by "weighing the various evaluations against one another and making a 'statesman-like' compromise among them", which is often proposed as a solution by those sharing Weber's kind of methodological perspectivism.
