Check out this hilarious Buzzfeed article, “28 Shocking Pictures That Prove That The Illuminati Is All Around Us.”
While it may seem comical at best, it is the only time I have seen such a sustained visual depiction of confirmation bias, satirical or not. The popularity of the article demonstrates that everyone can and does understand what confirmation bias is. Unfortunately, people tend to think they are less biased than everyone else (which is itself a bias), so that they simultaneously enjoy this Buzzfeed article and make fun of conspiracy theorists and superstitious worshipers, yet often believe in equally ridiculous things.
Namely, if you change the title to “28 Shocking Pictures That Prove That God Does Good Things All Around Us,” I have a feeling it would be much less satirical, and if it was, people would call to burn the writer at the stake. Of course, the punchline of the Illuminati images is that the criterion for being the Illuminati, i.e., being a triangle, is so vague that it can literally appear anywhere. Sound familiar?
(To be fair, at least there is definitive evidence that the Illuminati existed.)
