Concentrated media ownership reduces political accountability more than partisan polarization
When media ownership is concentrated in few hands, politicians face reduced accountability and can engage in corrupt or harmful behavior with less public scrutiny, more than partisan ideological polarization affects political outcomes.
Concentrated media ownership predicts reduced political responsiveness and increased corruption (George & Waldfogel 2006). Media competition drives accountability; monopoly markets have higher corruption and less investigative journalism. Effect is larger than partisan polarization effect on some measures. Structural concentration of information control limits accountability.

Quality and quantity of direct evidence for or against the claim — RCTs, systematic reviews, natural experiments, large cohort studies.
Strong evidence from George & Waldfogel (2006) and media market studies.
Whether the proposed mechanism is valid and established — does the how make sense, or are there fundamental flaws in the causal logic?
Mechanism clear: concentration reduces competition → less investigation → less accountability.
Degree of agreement among domain experts and relevant scientific or policy bodies — depth and quality of consensus, not just majority opinion.
Journalism and political economy consensus: ownership matters.
Whether findings hold across independent studies, populations, and contexts — resistance to p-hacking and publication bias.
Effects replicate across markets, time periods, and political systems.
