Here are a few options for a formal rewrite, depending on the specific focus of your content:
Option 1 (Direct and academic):
The Interplay Between Overconfidence and the Dissemination of Misinformation
Option 2 (Comprehensive):
An Analysis of Overconfidence as a Driver of Misinformation
Option 3 (Concise and professional):
Investigating the Relationship Between Overconfidence and Misinformation
Recommendation: If this is for an academic or research-based publication, Option 1 is the most professional and standard choice.
