Analysis / Bias

The Stockton Polling Institute conducts independent public opinion polling on elections, policy, and political trends in New Jersey. It does not publish political commentary or general news reporting; instead, it releases survey findings and data summaries.

Polling bias is assessed using Silver Bulletin’s mean-reverted bias metric. For the Stockton Polling Institute, the mean-reverted polling bias is −0.84, indicating a Democratic 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 Institute does not publish ideological commentary or partisan analysis, editorial bias is assessed at 0.

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 the Stockton Polling Institute in the Least Biased category, reflecting modest Democratic-leaning polling bias without editorial influence.
