American democracy has never suffered from a shortage of political opinions. Increasingly, however, it suffers from something more consequential: a shortage of institutions that citizens across the political spectrum trust to distinguish sound policy analysis from advocacy dressed up as analysis.
Modern political candidates rarely lack statistics supporting their positions. Whatever the proposal—tax cuts, tariffs, immigration restrictions, climate policies, healthcare reforms, minimum-wage increases, industrial subsidies, criminal justice reforms, or entitlement changes—there is usually a think tank, advocacy organization, consultant, or interest group capable of producing research suggesting that the policy will work.
The problem is not necessarily that these organizations fabricate evidence. Many employ talented researchers and produce serious scholarship. The deeper problem is selection.
A candidate can choose the assumptions, models, experts, and institutions most sympathetic to a policy and then present their conclusions to voters as objective evidence. Opponents can do precisely the same thing. One side produces a study showing that a tax proposal will accelerate economic growth. Another produces a study showing that it will dramatically increase deficits. One analysis says a regulation will save consumers money; another says it will destroy jobs. Each side cites experts. Each side has charts. Each side insists that the evidence is clear.
The average voter has little realistic ability to adjudicate between them.
Democracy therefore faces an information problem. Citizens are expected to choose between complicated policy platforms involving economics, law, national security, healthcare, energy, technology, education, and public finance, but few voters have the time or specialized knowledge necessary to independently evaluate the competing claims surrounding them.
