Say what you mean and mean what you say. A lot of arguments these days are about the meaning and usage of words. I’m increasingly dealing with this as a qualitative researcher. For one thing, the term ‘focus group’ gets used incorrectly all the time. But more importantly, understanding what research participants mean is tricky, as words are more emotionally loaded than they used to be. This makes my profession particularly valuable, as humans are very good (maybe better than robots) at parsing and understanding language.
