Introvert/extrovert/oral/anal/hysteric aren't meaningless in any sense of the word. They describe specific and intelligible concepts that are now irreversibly ingrained in cultural discourse. Whether you like it or not, they do and will continue to mean something for a very long time. I suspect you meant to make claims about plausibility or truth within scientific discourse rather than about the meanings of words.
