My ex, for whom English was a 2nd or 3rd language, often misused words, so I'd miss what she said next while I translated. The distinctions were probably just not clear to her. I later learned that one of her crazy variations had been learned as a local idiom. It took more years than we were married for me to finish translating some of what she said. I also had an ESL roommate who thought that a "e" at the end of a word was always silent. Decades later, I finally figured that out, and understood many puzzling exchanges.
Common sense is called that because it can arise without formal education, but it does not always do so. What gets called logic is most often rationalization. Most people can't tell the difference, being slaves to their emotions, and hobbled by Dunning-Kruger syndrome. Even expert logicians will disagree, because there is no consensus on the purpose of life, so all must be based on one's chosen assumptions.
For most of my life, I didn't realize that my IQ is double or triple my EQ. I expected people to grasp technical concepts quickly, and they still expect me to understand social situations without help.
