The appropriate response is to design your systems so they don't give contradictory indications.

Given that there will be problems with sensors from time to time, the systems should hand over control to the pilot with "I don't know sir, what do you think?" (or "Alors, je ne sais pas. Merde!" depending on manufacturer). Not hysterical "WE'RE STALLING, WE'RE GOING TOO SLOW" warnings when the nose is pointing at the ground and airspeed increasing. Not warnings that are directly contrary to what is actually happening.
Finally another person who gets this.
When the automation looses situational awareness it MUST silence all alarms. except the one that says "You now have manual control envelope protections are disabled"
This matter is common from AF447 to these two MAX accidents
