It’s not “digital media” it’s algorithmic based content curation. The old internet had far more conflicting information to the point you were skeptical about everything, but now social media controls what you see and feeds you an abundance of same-message content which leads you to draw a false conclusion between that information being popularly accepted as fact.

If 9/10 people told you something you were already KINDA suspicious about, like “JFK was killed by the CIA,” or something, you’re WAY more likely to think that is FACT than if 1/10 people told you that. The result is many people who are entirely convinced their beliefs are a clear, logical majority, no matter how outlandish it may be.
