Resumen
The article presents information on trust and etiquette in high-criticality automated systems. This article focuses on computers that occupy more traditional roles as complex and largely unpersonified machines involved in high-criticality working relationships with humans- where the consequences of failure can be catastrophic in terms of lives, money, or both. Politeness and social niceties are important in many human-human social interaction, but critical, highly technical work, there is the common misperception that we can "dispense with protocol" and get down to business, even with those who are not particularly courteous. In fact, excessive adherence to polite norms can seem stilted and sometimes frustrating in such settings. Here, the author argues the etiquette exhibited by non-personified machines (that is, ones largely without human methods of expressiveness such as facial expressions, speech, voice tones and gestures) and computer-based automation can profoundly affect users' perception and correct, optimal usage of them in work domains such as aviation, manufacturing and power plant operation, among others.
