When we don't want to believe something we ask ourselves, "Must I believe it?", and the answer is almost always, "No".
These are things that are difficult to verify but that we take by faith from reliable institutions (the more inquisitive and those with the privilege to be able to do so would have independently verified a couple of these claims and taken the rest on faith). And there are also many seemingly reliable institutions that mix up falsehoods and unsubstantiated claims among the more readily verifiable.
I don't know the exact percentage but it is certainly non-zero. Given that many elections in recent memory are won by margins of <10%, it doesn't matter if the majority has a BS detector since that majority isn't the target of "mechanized persuasion" aka A/B testing based advertising.
Sometimes they're not just underdeveloped, but completely and voluntarily turned off. Those who believe in bullshit conspiracies and as a result find themselves surrounded by other people believing the same absurdities are the hardest to convince. They might have been depressed loners before, and no matter how absurd their beliefs are, they introduced them into some form of society, and more importantly gave them a purpose in life.
Case in point, a friend of mine who believes every conspiracy his facebook friends throw at him. One day we were arguing about chemtrails, and after heavy reasoning and proof showing that it's all a lie from my part, he had nothing more to reply, so he went with "well, ok, then I want to believe in chemtrails, is that clear?". It might be that they need a bullshit story to feel them unite, then stronger, which would be like gold for conspiracies creators. QAnon very likely feeds on that.
I'm not at all surprised Christians fall for Trump's lies and Qanon.
Such arrogance. Faith (of any kind) increases humanity.
[EDIT]: meant to say "they wouldn't be into religion"
it turned out later that it was a 30 year old man who had just murderer someone and had a gun in his hand
There is a need to discuss restoring confidence in institutions.
certainly its roots a and strength is/was 4chan based.
The fact that people who's social and even fiscal success is based in the circles of the evangelicals, are finding themselves very comfortable in the QAnon world just seems like a natural fit.
But it stretches much further than that. I know people that are Deep QAnon consumers that are non religious, living in very secular countries and have logic based (read IT), white collar type jobs.
Don't let yourself forget that gullible and willfully misled comes from all shapes and sizes and from all sectors in society.
This is a spurious claim to make. Do you have any evidence of this? 4chan and 8kun have different owners who both hate each other.
Spreading gossip about problems as big as this does nothing good.
