Where it sits among the Inland Empire's outlets#
~1.3 local articles/day · 20 scored
How to read this: left and right is ideological tilt. This market's outlets sit close together, so the map shows lean from -2 to +2 of the full -3 to +3 scale. Zoomed in, small gaps look large: each outlet's lean is averaged over 12 to 83 scored articles, so a gap of a few tenths may not hold as more are scored. Up is source independence, meaning official claims are tested rather than passed along. Bubble size is local articles per day: publishing volume, not audience reach. Dashed outlines mark the known-lean control and the out-of-market reference. The moose marks our own newsroom. Hover or tap any bubble to spotlight it and see its exact numbers.

How this is measured#
Three models from three vendors score each article against a published rubric, with outlet names and bylines removed first. An outlet's number is the mean of its per-article panel medians. Lean measures direction only, never quality. The full method, its validation checks and every outlet's numbers are on the Inland Empire Media Bias Scorecard.
