Mainstream media tend to just mouth the conventional wisdom, to see everything through the filter of right and left.

Huffington criticizes what she sees as a herd mentality in large news organizations: instead of interrogating assumptions, they repeat “conventional wisdom” and frame events within a familiar partisan binary. The phrase “mouth” suggests unthinking recitation rather than independent judgment, while the “filter of right and left” implies that complex realities are reduced to predictable ideological templates. The remark aligns with a broader argument often made by media critics: that institutional incentives—access, speed, audience expectations, and professional norms—can narrow the range of acceptable interpretations. Implicitly, she is calling for journalism that is less captive to partisan framing and more willing to challenge consensus narratives.
