When I've pointed out a Q proof to a doubter--usually when Q says something and then on the delta, anniversary of the post, Trump says the same thing, they will say "it is just a coincidence."
If you show them multiple Q proofs, they will say it is "confirmation bias"--the tendency to interpret new evidence as confirmation of one's existing beliefs or theories.
They will insist that you are finding these coincidences because you are actively looking for them, and in time, they will show up. Think of if you just buy a new red Ford Focus. Suddenly you start noticing all of the other red Ford Focuses on the road.
Here is why this theory falls flat. If the Q proofs and the incredible coincidences were simply a case of "confirmation bias," we would be finding them everywhere than just Q proofs.
Anons would be finding these coincidences in Twitter posts by Ted Cruz, Hannity, Kari Lake, or any other conservative personality. The fact is that nobody ever never finds these concidences anywhere other than Trump (80%), Scavino (10%), Military (8%), Trump Family and others close to the President's mission (2%).
Of course, these people are the intellectually lazy types that will allow the TV to do the thinking for them, so good luck getting most of them to look into it further themselves.
Edit: Note: I'm referring to social media and public comments only made by public figures. World events that match up to Q posts would be in a category of its own.
I also edited the percents after someone mentioned Scavino often posts Q proofs, which I completely forgot about.
There's hundreds of these "coincidences" at this point. Each one, taken individually, can be written off as coincidental. Take a handful of them and it's mathematically improbable. Take them all, and I'll bet my left and right nut that something is going on in the background, out of public view.
Add up every one and it becomes impossible to say Q isn’t real.
