See: The Internet Is Worse Than a Brainwashing Machine
“… misinformation is powerful, not because it changes minds, but because it allows people to maintain their beliefs in light of growing evidence to the contrary. The internet may function not so much as a brainwashing engine but as a justification machine.”
“This dynamic plays into a natural tendency that humans have to be evidence foragers, to seek information that supports one’s beliefs or undermines the arguments against them. Finding such information (or large groups of people who eagerly propagate it) has not always been so easy. Evidence foraging might historically have meant digging into a subject, testing arguments, or relying on genuine expertise. That was the foundation on which most of our politics, culture, and arguing was built.”
“The current internet—a mature ecosystem with widespread access and ease of self-publishing—undoes that.”
