"If it’s a too high AoA signal causing the unreliable airspeed, we can assume the stall warning will be on for the affected pilot from liftoff. This will cause the artificial Yoke feel system to increase the Yoke force. The flying pilot will feel he needs an increased back force on the Yoke to hold the aircraft level."

737MAX elevator feel system pressure is a function of stabilizer position, impact pressure, and AOA. The AOA dependency provides increased feel stiffness when AOA is near stall AOA. This has been added to provide one of the characteristics associated with stall identification "nose down pitch that cannot be readily arrested".
