Not trying to disagree with anyone or stir the pot, I would like to learn more. I would still like to see proof on the torsional moment theory.
If I understand your question on the proof you seek, I think you may be able to prove this theory to yourself very easy by taking an uncovered open bay wing panel with a relatively small D section and performing a torsional twist test, you will find that it will twist very easily. Now cover both sides that same wing panel and try and torsionally twist it, you will see and feel the difference like night and day.
