Mitigated Speech and Its Detrimental Impact on Aviation Safety

Key Insight

Mitigated speech refers to any attempt to downplay or soften the meaning of what is being said, often used for politeness, shame, embarrassment, or deference to authority. While appropriate in many social contexts, it becomes a critical hazard in high-stakes environments like an airplane cockpit during an emergency. Linguists Ute Fischer and Judith Orasanu identified six levels of mitigation, ranging from a direct 'Command' ('Turn thirty degrees right') to a subtle 'Hint' ('That return at twenty-five miles looks mean'), with intermediate levels like 'Crew Obligation Statement,' 'Crew Suggestion,' 'Query,' and 'Preference.'

Their study revealed that captains, speaking to subordinates, overwhelmingly opted for direct commands, whereas first officers, addressing their superiors, predominantly chose the most mitigated forms, often hinting. This mitigation is problematic because hints are the most difficult requests to decode and the easiest to disregard. A stark example is the 1982 Air Florida crash, where the first officer repeatedly hinted about dangerous ice on the wings using phrases like 'Look how the ice is just hanging on his, ah, back, back there, see that?' and 'Boy, this is a, this is a losing battle here.' He only escalated to a 'crew suggestion' just before takeoff, and the captain's delayed agreement came only as the plane plummeted.

Mitigation helps explain the anomaly that crashes were historically more likely when the captain was flying, despite their greater experience. This is because the second pilot, in a subordinate role, is less likely to speak up assertively. Combating mitigation has become a central focus of 'Crew Resource Management' (CRM) training in commercial aviation, teaching junior crew members standardized, assertive communication procedures to challenge captains when safety is at risk, such as 'Captain, I'm concerned about...' followed by escalating statements. This 'war on mitigation' is credited with significantly reducing airline accidents in recent years.
