Who gets to decide what information is "disinformation" and what is the right information?
Any view that you do not approve of is not disinformation.
Also, you are smart enough to recognize disinformation.. but you think everyone else around you is too gullible and would fall prey to "disinformation"
But disinformation isn't just incorrect information. Disinformation is false information seeded with an intent to mislead the population. The person who "gets to decide" what is disinformation is effectively the person who is planting the disinformation.
Once the disinformation starts to propagate then the downstream propagandists may believe they are spreading legitimate truths, but ultimately by definition the disinformation can be traced to a source that intended to deliberately disinform.
Also, not everyone around us needs to be gullible for disinformation to work. In the US for example we live in a country where national elections are routinely decided on razor thin margins, where just a couple of percent or less can flip the results. We also live in a nation where 32% of people believe in ghosts [0]. So there are enough gullible people for the type of disinformation that wouldn't persuade a reasonable person to still yield powerful results.
If the concept of ghosts are disinformation, who's the person that intentionally planted this seed? Even if that's the case, you'd have to go back thousands of years at least.
You seem to be convinced that ghosts don't exist. Why is that? Note that absence of evidence is not evidence of absence. Among the millions of potentially fraudulent claims from people reporting to have seen ghosts, just one legit claim would suffice to contradict your premise. I don't know how good those odds are, but I'm guessing they're probably not as bad as you seem to believe.
On the contrary, the claim that "ghosts don't exist" seems to be a prime candidate for being disinformation. Pretty useful thing for secular institutions to have the population believe (regardless of its truth value) if only to wrestle power away from religious and spiritual institutions.
Any view that you do not approve of is not disinformation.
