That’s an interesting thing you point out. I’m a computational social scientist and I’ve really only seen this with colleagues whose native language doesn’t have pluralization morphology to begin with (East Asians usually). Since code is an irregular pluralization in English, it trips them up. Perhaps it’s a combination of: Learning to program informally (as most scientists do) Being a non-native English speaker My native English speaking colleagues or those from Europe, India, Africa, South America, pluralize code as code. I didn’t like, do a study on it or anything this is just a pattern I’ve noticed, so your mileage may vary.
