"The opposite of truth is not just a lie. The opposite of truth is chaos." --spoken by Nikki Alexander, forensic pathologist in the BBC television series Silent Witness.
Almost no one argues about who won the Super Bowl. The team that loses doesn't refuse to leave the field. The integrity of the game rests on a social contract--that people will accept the outcome of a competition, even they they weren't present at the game, even if they did not watch the game on television.
Why, then, do people refuse to accept factual information as true and choose to believe something false instead? The psychological and social dynamics of disinformation, media manipulation, and conspiracy theories are complex. Weaning people who are deeply committed to conspiracy theories (QAnon, AntiVaxxers, and the like) off their dependence on these false conspiracy theories may require approaches similar to those used to help people with treating addiction and cult issues.

For insight into one aspect of how media disinformation is spread, see this report on "source hacking" that lays out the specifics on how media manipulators work: Source Hacking: Media Manipulation in Practice [4 September 2019].
Misinformation Reinforces Existing but False Beliefs
"...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. A rationale is always just a scroll or a click away, and the incentives of the modern attention economy—people are rewarded with engagement and greater influence the more their audience responds to what they’re saying—means that there will always be a rush to provide one."
