You would think.
Funny story. As a grad student in Israel, I worked as an English language typist (cause I needed cash) in the science teaching office of the university at which I was studying. (The office was responsible for preparing a lot of the science teaching materials used in Israeli high schools.) There was one particular professor, Israeli-born, who wrote a lot of articles about educational theory (and a lot about Piaget) for publication in English language journals. His use of the English language was horrendous, and I ended up editing (without changing the meaning) a lot of what he gave me to type up so that it was in proper English. I'm not sure if he ever noticed. He never said anything, just accepted back whatever I had typed up for him.
