Rules of good writing (2007)

>Readers comprehend “the boy hit the ball” quicker than “the ball was hit by the boy.” Both sentences mean the same, but it’s easier to imagine the object (the boy) before the action (the hitting). All brains work that way.

I agree with this, but I doubt that all brains work this way. It's probably true of almost all English speakers.

I think the processing effort is likely a side effect of English mainly using sentence constructions that go subject->verb->object. Not all languages do that, so I suspect that your brain has an easier time processing whatever's most common in the language.

Over 80% of the world's languages are classified as SVO or SOV, actually, and probably over 90% of all first language speakers today speak one of these two. Their overwhelming dominance compared to the other four possibilities have led researchers to conclude there may actually be a cognitive benefit to putting the subject first.
