Checkboard I'm not necessarily sure that's the case.
Imagine using ailerons in a stall situation (a BIG no no!) you merely deepen the stall on the wing with the downward moving aileron by increasing the AoA, this being one of the reasons that you may get a wing drop. I would suggest that using flaps in the case of a wing stall you would deepen the stall on both wings.
The standard stall recovery is to reduce the angle of attack of the wing, to unstall it. To use flaps or ailerons has the opposite and completely unwanted effect.
As I understand it a tailplane stall causes stick force reversal and leads to the elevator being forced into the nose down position, or vice versa, and the reason a hefty pull is required is to overcome this force (which can be huge).
