They pick the unscientific to speak because they will choose terms that are more accessible to everyone else. To use a precise word, your audience would be limited. They are not as adept at translating things into human terms as some of us that were sent to "research". The way you speak about these terms contains the process that many can use to come to a more complete understanding. Those with the science that watch can then come forward to clarify the language, once an understanding is reached. In school you would not benefit as much if you memorized a text as if you understood the concepts; in Earth School we may not even have the language yet for what we are now uncovering.
