I guess this more caught my eye, and yet again, I think this is stating the obvious? By nature we anthropomorphise everything. From insect to Gods. As such, surely it is to be expected that looking for deeper meaning to events is naturally going to follow? I guess it is in a way vanity, but I think it also shows curiosity.
I agree on anthropomorphization (whew! mouthful) however there are degrees of such I'm sure and I think those with a more critical mind can recognize it even when they happen to be doing it. That's the difference I think. I do it myself more often than I would like though as you say, we all do it so it's kind of like trying not to inhale smoke inside a burning building.
