Have you never tilted your head when you hear (or even just think about) a piece of interesting / surprising / confusing information?
Now, I don't know why _humans_ tilt our heads, but it has always been clear to me with my dogs that they are doing the exact same thing. They're pausing to think a little harder in response to something new.
I'm surprised they didn't come across such an explanation from their supposed online search. It just seems too obvious a thing no to come up at least once.
I tilt my head when I'm trying to make sense of a word I heard, other people do it, anime characters do it.
It's good to study things rather than make the assumption but it's weird sometimes how they come at these animal behavior studies and at least make it sound like "huh! how strange, why on earth would animals do that?" when the same behavior happens in humans in roughly the same situations.
