Since people are discussing conspiracies, I present to you the Batman argument to inoculate your near and dear ones.

1) All conspiracy theories require the evil organization to achieve several super human/ super organizational feats such as: * Perfect coordination - across timezones, personalities, objectives * Great wealth * excellent control of public figures * Advanced technology * Great secrecy Etc.

These are all impossible asks, which any normal person knows if they have worked in any team of people.

Many conspiracies die because of how hard it is to keep everyone aligned, and if people were that efficient in secrecy, imagine how efficient they would be without that burden.

Therefore,

Implication 1) If you believe in the conspiracy, we must also live in a world where such levels of efficiency are possible.

which means that

2) It is also possible for an organization or individuals to exist, who take advantage of these efficiencies and advantages to do "good".

Now if it was possible to stay in the dark, while having advanced tech and great wealth - well you've just described Batman.

So the question you can train all your loved ones to ask, anytime they encounter a great claim, is whether this claim means that we live in a world where batman can exist.

------------------------

While this is a childish way to encode a defense, its meant to be easy to consume, and to protect people who regularly wont have time to spend the effort to verify information or toxic content when they encounter it.

So while it is outlandish, that is partly the point - to diminish the earnestness and terror that conspiracy theories exude, without your active intervention being required.

edit: This can apply to any superhero/or superfriends. I just chose Batman.
