Committees became essential in US state legislatures' decision-making over the 20th century.

But understanding their power has been tricky—did they really wield more influence than previously known?

Researchers now have a clearer way to measure it.

Using legislative documents from ten sessions, this study rates committees across six dimensions of structural authority in both houses.

Power Assessment Methodology

* Analyzed diverse legislative materials spanning multiple decades (1900s-1990s)

* Established six distinct criteria to evaluate committee influence:

* Rulemaking capacity

* Document control ability

* Amendment power scope

* Member appointment sway

* Committee chair authority level

* Subcommittee creation latitude

Key Findings & Insights

* Reveals significant variations in committee strength across states and between legislative chambers (Senate vs. House)

* Uncovers patterns in how influence shifted throughout different historical periods

* Demonstrates that power structures were not uniform but adapted uniquely to each state's context

Wider Significance for Political Science Researchers

These ratings offer unprecedented tools.

They help track committee evolution over time and compare institutional designs across states.

This resource provides concrete data needed to study legislative representation theory, interest group influence dynamics,

and the overall functioning of democratic institutions more accurately than ever before.
