Analysis / Bias

In review, Gallup presents news based on analysis from polling data. Besides polling data, Gallup publishes news that is low biased and does not use loaded terms such as this: U.S. Church Membership Down Sharply in Past Two Decades. This is sourced back to a Gallup poll that provides a methodology. 

Polling bias is assessed using Silver Bulletin’s mean-reverted bias metric. For Gallup, the mean-reverted polling bias is +0.57, indicating a slight Republican lean. Under MBFC’s calibrated polling bias scale, a mean bias between -0.6 and -1.0 corresponds to a polling bias score of +2. Polling bias accounts for 70% of the final bias score, while editorial bias accounts for 30%.

Applying MBFC’s weighted formula:
(+2 × 0.70) + (−0 × 0.30) = +1.4

Based on MBFC’s bias classification scale, a final score of +1.4 places Gallup in the Least Biased category.

Factual reporting is rated Mostly Factual based on a Silver Bulletin grade of B+, indicating solid predictive accuracy and good methodological performance.
