Analysis / Bias
The Tarrance Group conducts political polling and strategic research primarily for Republican candidates, campaigns, and party organizations. The firm does not publish political news reporting; its website primarily releases polling summaries and firm-related updates.
Polling bias is assessed using Silver Bulletin’s mean-reverted bias metric. For The Tarrance Group, the mean-reverted polling bias is +0.87, indicating a 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%.
Because the firm works almost exclusively for Republican candidates and organizations, editorial bias is assessed at +5.
Applying MBFC’s weighted formula:
(+2 × 0.70) + (+5 × 0.30) = 1.4 + 1.5 = +2.9
Based on MBFC’s bias classification scale, a final score of +2.9 places The Tarrance Group in the Right-Center category.
Factual reporting is rated High based on a Silver Bulletin grade of A-, indicating strong predictive accuracy and reliable methodological performance.
