I think it’s because humans can easily confuse the pull caused by gravity with a pull caused by acceleration. We could tell the difference using the visual cues when we run or jump… but if you are sitting in the plane, the plane moves together with you, so all objects inside the plane are constantly giving you the wrong cues.
In other words, the plane is “far from natural”. Not being from West doesn’t help a lot here. Perhaps coming from an alien civilization where kids spend most of their time in flying saucers would make a difference.

It’s not just humans—the basic idea of general relativity is that (short of looking out or detecting tidal effects) it’s impossible in principle to tell them apart.

Running a lot is something quite natural for humans but not done much by Westerners. That means that the default mode of feeling pull is not well developed. Because it’s unclear what you are actually feeling it’s more difficult to adept to the changing meaning of the feeling.

I didn’t see much running in Japan nor China either. :)
Saying that for every elements in X A is true doesn’t that for all elements that aren’t in X A isn’t true. Logic doesn’t work that way.
My sentence doesn’t make statements about the amount of running being done in Japan or China.
