In Gilens and Page 2014 Testing Theories of American Politics, biased pluralism is the ideal-type theory that organized interest-group competition is skewed toward corporations, business associations, and professional groups rather than the preferences of average citizens.
Use this concept for the paper's category-level finding that business-oriented interest groups have greater aggregate modeled impact than mass-based interest groups and that the interest-group universe is not a reliable transmission belt for average-citizen preferences.
This concept page does not prove that any named business group caused a specific outcome or acted with a specific motive. Use it as a theory and aggregate-model anchor, not as a specific relationship claim.
