Definition
A pattern of thinking in which a person attributes their successes to their own skill or judgment, and attributes their failures to outside factors such as bad luck, weather, equipment, or other people. In aviation human factors, self-serving biases are recognized as a hazard to pilot decision-making because they prevent honest self-assessment and block learning from mistakes.
Plain English
The tendency to take credit when things go well and to blame something else when things go wrong.
Context Anchor
Encountered in pilot decision-making, instructor debriefs, accident discussions, and personal review after a flight.
Derivation
From 'self-serving,' meaning acting in a way that benefits oneself, and 'bias,' a leaning or slant in thinking. Together: a slant in judgment that protects one's own self-image.
Why Pilots Care
This bias can block honest self-assessment, reduce learning from mistakes, and increase the chance of repeating unsafe actions.
Analogy
It is like a student who says a good grade proves they are smart, but a bad grade only proves the test was unfair. The pattern protects pride, but it blocks learning.
Intuition Check
Self-serving does not mean intentionally selfish here. It means the mind is favoring an explanation that makes the pilot feel less at fault.
Example Sentence 1
During the post-flight debrief, the instructor pointed out that blaming the rough landing entirely on the crosswind was a textbook example of self-serving biases.
Example Sentence 2
When the approach became unstable the pilot blamed the controller instead of recognizing their own late descent planning.
