I'm not saying that the conclusions in the article are false. As a programmer, I prefer composition to inheritance, too. I'm saying that the justifications are presented using a scientific term of art (cognitive load), but the scientific evidence regarding cognitive load isn't sufficient to justify these claims.
I don't think the readers really care about the scientific term in this context. It's a shared experience that we care about and implicitly understand. It's probably worth "researching" (in the scientific sense).
