Here are a few ways to rewrite the title in a formal, academic tone:
- USC Viterbi Study Finds That Disseminators of Misinformation Possess Smaller Followings Than Those Rebutting Them
- USC Viterbi Researchers Observe Smaller Audience Reach for Misinformation Promoters Compared to Fact-Checkers
- Study Indicates That Users Countering Misinformation Maintain Larger Followings Than Those Spreading It
Recommendation: The first option is the most precise and formal, clearly stating the findings of the USC Viterbi study.
