Social Influence Bias: A Randomized Experiment
Research-assisted source review
- What it supports
- An arbitrary positive rating increased later positive ratings and final scores, producing cumulative herding; negative manipulation was more often corrected by later users.
- Where it may not transfer
- One platform, rating system and period limit transfer. Votes may reflect visibility, interpretation or strategic response, and the experiment does not establish improved choice or user welfare.
