The Same Promotion, Two Different Stories
When you get promoted, you can point to the work you remember doing: the late fixes, the hard decisions, the skills you built. A coworker’s promotion is harder to explain from the outside. You see the outcome, but not the full trail of effort or setbacks that led to it. That gap makes it easy to credit your own success to ability and effort while chalking someone else’s up to timing, favoritism, or luck.
Why Our Own Effort Feels More Visible
Psychologists often describe this pattern as a self-serving bias: people tend to explain their successes in ways that protect or enhance their sense of competence, while explaining failures in ways that shift blame outward. It is not necessarily a conscious choice. Your own intentions and behind-the-scenes work are available to you; another person’s are mostly hidden. So the explanations that feel obvious are built from unequal evidence.
There is a related habit called the fundamental attribution error: when judging other people, we often overemphasize personal traits and underweight the situation. A coworker may look “lucky” because you cannot see the extra assignment that put them in front of a decision-maker—or the years of preparation behind a moment that appeared sudden.
A Bias That Can Feed Itself
These stories can shape what happens next. If you assume your promotion came from merit alone, you may overlook the help, timing, or opportunities that also mattered. If you assume a colleague succeeded by luck, you may discount their strengths and miss what you could learn from them. In a workplace, that can quietly turn recognition into resentment.
A useful check is to ask what evidence you have about each person’s contribution—and what remains invisible. The promotion may still reflect real skill. The point is that we usually have a fuller account of our own effort than anyone else’s.
