shapiro noted political jurisprudence as having two wings, the macro wing and the micro wing. the macro wing looks at courts as players in the political process. in their processes of decision making, they entertain matters from different interest groups hence shape policy through pressure from these. the micro wing looks at individual decisions of judges. the second wing is a manifestation of charles h. pritchett who introduced behaviorism into usa judicial studies after studies that showed individual decisions in courts have been increasing since the days of president roosevelt.
