O.C.
The Red Herrings become a shoal. Direct v Indirect input now. Instruments, AirTren, instruments are the key. They are not fooled by panic, tension, stress or any of the other factors which so much mess up human perception. They can be relied on to give an accurate reading of a situation provided you remember your training and cockpit drills. No need to look at the yoke or whatever, look at your instruments. One can be sure that BEA know who was making the inputs - a yoke is not needed for that. As for the flight crew they also knew so where does the yoke help? A yoke is a piece of equipment to transmit inputs to the aircraft it is not a magical cure all to save lives. It performs its function like sidesticks do and some pilots prefer it. This is human nature not everyone likes the same thing. But it is not superior in any way to a sidestick.
Only partially correct I think. Up until the stall, the instruments did tell the story of what the inputs were.

After the stall, the aircraft began to act perversely in roll and pitch, and at that point, the control inputs were masked by the aircraft's gyrations.

This must have been immensely confusing to both the PF and PNF.
