Do ec135 pilots wear gloves? - think the real issue is how all this information from the 5 senses is processed with about 100 billions of neurons. If these neurons get conflicting or for them irrational information, they start to have a big battle who is right or wrong. Which part of the brain will dominate in the decision making (if there is any and not only confusion)? What information stored (knowledge, training, experience) will be used? very basic survival instincts could dominate (fight, flight, freeze). In serious stress situations people, also very experienced pilots, can react very differently to what would seem normal or appropriate for an outsider not understanding the whole situation the person and his cognitive system is confronted with.
The cognitive system could be also affected by underlying factors such as a simple infection of a vital part of the cognitive system. That could be a gland for example. Very often these infections are not discovered. Or a tick bite and then Lyme disease. Very often not tested. If the body is fighting such a problem, perhaps already over a long period, the reaction to immediate serious stress might be different as it used to be in normal 'healthy' conditions. Human factor is not always human error. The factors for the 'errors' are not clear but some indications are already pointed out.
