Analysis / Bias
Impact Research conducts political research and polling on a wide range of topics, including elections. The website publishes news related to its polling but openly disclaims its progressive bias. Further, the majority of clients are Democrats.
Polling bias is assessed using Silver Bulletin’s mean-reverted bias metric. For Impact Research, the mean-reverted polling bias is −1.32, indicating a moderate Democratic lean. Under MBFC’s calibrated polling bias scale, a mean bias between -1.0 and -1.5 corresponds to a polling bias score of -3. Polling bias accounts for 70% of the final bias score, while editorial bias accounts for 30%.
Applying MBFC’s weighted formula:
(−3 × 0.70) + (−3 × 0.30) = −3.3
Based on MBFC’s bias classification scale, a final score of -3.3 places Impact Research in the Left-Center category.
