Mentally, I understood that this was true, but this sentence just really made me have a new appreciation for this. We're always doing problems which are similar to real world solutions, but they aren't real. Like how correlation doesn't equal causation. I still had a bias that A is affected by B so C. In the real world though, that's just not true. Like the old meme, I added below. People just think differently, and neither is exactly wrong.
