I don't know if your assessment of the study is valid (it seems a little simplistic to think that they wouldn't account for this to be honest), but what you describe is classic Survivorship Bias. Here's an entertaining video from Derren Brown that shows how to use this technique to convince people you have psychic powers: [this video] Edit: also see the comment about the Miracle Man scam in this thread.

For a good example of confirmation bias watch Derren Brown's "The System" [1] where he makes a woman believe an unknown benefactor has a foolproof system for betting on horses. "Mail Order Prophet" [2] by Alfred Hitchock has a similar idea. [1] [this video] ] [2] [LINK]

On the other hand objective randomness is a black box. You can describe how it behaves at the surface level (so functionally it is usable), but by definition you can't have a finite model of it, so what is inside? No answer by definition - something infinite. So why X happens instead of Y? 1. Let's propose an unexplainable, unmodellable infinite entropy source under everything vs. 2. X happens and so do Y, and one is observed at a certain probability due to anthropic principle - like this: [this video] The first is somehow psychologically less satisfying answer for me, although - of course - I accept that calculation works either way. The second at least not an unimaginable infinite, and in the e
