If the pilot corrects the wrong problem, or if response is not appropriate, it means that the effective aircraft is NOT OBSERVABLE to him : not enough or not the good sensors and data to analyse the situation, or wrong connection in HMI (human machine interface partS, first of all SOPs, CRM, training, selection, health, etc.).
I say it never enough : To work a dynamic system has FIRST to be
observable and controllable. Stability, sensitivenes, robustess, optimisation, price, etc. come long after.
