I think you are thinking of a complete belief in magical thinking, whereas this is talking about the "magical" type of thought that "this car does not like you to use full throttle until its warmed up", or feeling anger at a beer bottle with a top thet "doesn't want to come off". If you stop and reflect of course you know its nonsense, but I bet you sometimes have those thoughts anyway.
Maybe, but at that point you're not really talking about beliefs, you're talking about the quirks of language, which is something very different. For example, in the case of the bottle cap "not wanting" to come off, you're not anthropomorphising the bottle at all. You don't believe that the bottle has a life or a mind of its own. More often than not, you're commenting on your own inability to achieve the desired result. Maybe it evolved linguistically from magical belief, but I doubt it.
And before anyone gets too excited about all this, I found a research paper which finds that most findings in research papers are false.
