Definition
In aviation human factors, social influence is the effect that other people — crew members, instructors, passengers, controllers, or company culture — have on a pilot's decisions, behavior, and judgment. It includes pressure to conform to group expectations, deference to authority, and the tendency to go along with what others are doing rather than acting on independent assessment.
Plain English
It's how the people around you change what you decide to do, sometimes without you realizing it. You might fly when you shouldn't because everyone else is, or stay quiet about a problem because you don't want to push back on the captain.
Context Anchor
Seen in pilot decision-making, human factors, and risk management discussions, especially when passengers, instructors, other pilots, or outside expectations affect a flight choice.
Derivation
Social comes from a Latin word meaning companion or ally. Influence comes from a Latin idea of something flowing into something else. Together, the words point to how the people around a pilot can quietly flow into, or affect, the pilot’s decisions.
Why Pilots Care
Unmanaged social influence can cause a pilot to ignore personal limits or safety procedures to please passengers or other crew.
Intuition Check
Social influence does not mean only obvious peer pressure. It can be subtle, such as wanting to please passengers, copy another pilot, avoid embarrassment, or meet someone else’s schedule.
Example Sentence 1
The accident report cited social influence as a factor: the first officer noticed the unstable approach but didn't speak up because the captain seemed comfortable.
Example Sentence 2
Good CRM training teaches pilots to notice social influence and speak up when it conflicts with safe procedures.
