does structural network bias explain mainstream media trust gaps 



Structural network bias—interlocking ownership, shared elite sourcing, and cross-outlet amplification—explains part of mainstream media trust gaps, but not the whole.

Documented admissions show elite overreliance

and cultural overcorrection . Network effects create correlated blind spots: covering elites while ignoring average viewers , skewing framing on charged conflicts like Israel/Hamas , and fueling anti-Trump animus . This homogeneity makes selective coverage and partisan advocacy systemic, not accidental. The dismissive attitude toward mainstream outlets reflects perceived network gatekeeping.

However, trust gaps also track audience polarization and ideological identity, which network structure alone cannot explain. Known: explicit bias and elite focus. Inferred: network effects amplify these, but uncertain is the causal isolation from demand-side factors (e.g., viewers preferring partisan news). Thus, structural network bias is a powerful aggravator, but insufficient as a sole explanation.
