In Gilens and Page 2014 Testing Theories of American Politics, majoritarian pluralism is the ideal-type theory that organized interest groups, taken together, represent citizen interests broadly enough that group competition tends to yield policy outcomes aligned with average citizens.
Use this concept when distinguishing citizen-representing pluralism from business-skewed or biased pluralism. Gilens and Page report that overall interest-group alignment is not substantially correlated with average-citizen preferences, and that mass-based groups have weaker aggregate impact than business-oriented groups in their separated model.
This page does not show that every mass-based organization fails to represent its members or average citizens. It summarizes the article's aggregate model and supplement coding categories.
