Why Success Can Feel Like a Con You Are About to Get Caught For

A promotion arrives, a big project lands successfully, a performance review comes back glowing, and instead of settling into the achievement, a specific and uncomfortable thought surfaces: any day now, someone is going to realize this was luck, or timing, or someone else's work, and the whole thing will unravel. This experience has a name, and it has been studied directly since the late 1970s.

Psychologists Pauline Clance and Suzanne Imes first described what they called the impostor phenomenon in a 1978 paper, based on their clinical work with a group of high achieving women who, despite real and substantial accomplishments, could not internalize their own success as earned. Clance and Imes were deliberate about calling it a phenomenon rather than a syndrome, since they were describing a common pattern of thought, not a diagnosable disorder.

Their original 1978 paper included a specific claim worth examining directly, since later research corrected it in an important way. Clance and Imes initially speculated that men experienced this pattern with much less frequency and intensity than women, reasoning that prevailing social stereotypes led women to attribute success to luck while men attributed success to their own inherent ability. A decade later, in 1988, Clance and a colleague named O'Toole revisited this claim and concluded the earlier speculation had not held up: subsequent research found men reporting the impostor phenomenon at rates roughly comparable to women.

This correction matters because the original, mistaken version of the finding is still what most people half remember, if they have heard of the concept at all: that this is primarily something women experience. A man dealing with a persistent, private sense of being a fraud despite clear evidence otherwise is not experiencing something unusual for his gender. He is experiencing something the original researchers themselves found, once they looked more carefully, to be just as common in men.

Part of what sustains the pattern is that achievements get explained away in real time, almost automatically. A promotion becomes luck, or good timing, or a manager who simply likes him, rather than evidence of competence. A difficult project that succeeded becomes proof that the bar was set low, rather than proof of skill. Each new achievement, instead of accumulating into confidence, gets filed under exception rather than evidence, which means the underlying belief that one is secretly unqualified never actually gets tested against the growing pile of contrary proof.

A related pattern, sometimes called overworking, tends to accompany this: putting in far more hours or effort than a task objectively requires, driven by a private fear that anything less than maximum effort would finally reveal the fraud underneath. The overwork sometimes produces genuinely strong results, which then gets attributed to the overwork rather than to underlying ability, which quietly reinforces the belief that ability alone would never have been enough.

Clance later expanded on this in a 1985 book, describing what she called the impostor cycle: anxiety about an upcoming task leads to either frantic overworking or, just as often, procrastination followed by a frenzied last minute push, and the resulting success, however it was produced, gets attributed to the extraordinary effort or the narrowly avoided disaster rather than to underlying competence, which resets the cycle for the next task rather than closing it.

What tends to interrupt the cycle is not more achievement, since achievement is exactly what the pattern is already resistant to processing as evidence. It is naming the specific mental move happening in real time, catching the moment an achievement gets automatically reattributed to luck or circumstance, and deliberately asking what a neutral outside observer, looking only at the actual outcome, would conclude instead.

None of this makes the discomfort disappear immediately, and it is not a reflection of any real deficiency. It is a well documented pattern that researchers have now been studying directly for nearly fifty years, one that the people who coined the term themselves found does not spare men, however differently that finding has been remembered.
