Impostor Syndrome: What Psychology Research Describes About Causes and Responses
Impostor syndrome, also called impostor phenomenon, has received substantial research and popular attention. This summary pulls from psychology research, mental health resources, and published studies to describe what the evidence shows about impostor syndrome, what causes contribute to it, and what approaches evidence supports.
This article does not claim personal experience with impostor syndrome. The information below reflects what published psychology research and resources describe.
What Impostor Syndrome Is
The APA’s work stress resources describe impostor syndrome as a pattern of thinking in which individuals doubt their accomplishments and have a persistent internalized fear of being exposed as a fraud. Reviews consistently note that impostor syndrome involves:
- Attribution of success to external factors (luck, timing, deceiving others)
- Discounting of one’s own abilities
- Fear of being exposed as incompetent
- Often accompanied by overwork to compensate
The concept was first described by psychologists Pauline Clance and Suzanne Imes in 1978, and has been studied extensively since.
What the Research Shows
Published research on impostor syndrome includes:
Prevalence: Reviews consistently note that impostor feelings are reported across many populations, with studies finding substantial minority to majority of various professional groups experiencing these feelings.
Demographic patterns: Reviews note that impostor syndrome has been studied particularly in high-achieving populations including medical students, graduate students, and professionals in various fields.
Outcomes: Reviews consistently note that impostor syndrome is associated with increased anxiety, burnout, reduced job satisfaction, and lower self-esteem in some studies.
Functional variation: Reviews note that impostor feelings exist on a spectrum, with mild occasional feelings being common and persistent severe feelings being more rare but more impactful.
What the Evidence Identifies as Causes
The published research consistently identifies several contributing factors:
Family environment: Reviews consistently note that family dynamics, particularly high-achieving families or families with conditional approval, are associated with impostor syndrome development.
Personality factors: Reviews note that perfectionism, neuroticism, and low self-esteem are associated with impostor feelings.
Achievement contexts: Reviews consistently note that competitive environments and high-achieving peer groups are associated with impostor feelings.
Gender and cultural factors: Reviews note that impostor syndrome has been studied particularly in women and in some minority populations, with associated cultural and social factors.
Imposter cycle: Reviews consistently note that impostor syndrome can perpetuate itself through attribution patterns (success attributed to luck, failures attributed to inability).
What the Evidence Supports
Published research supports several approaches for addressing impostor syndrome:
Cognitive restructuring: Reviews consistently note that identifying and challenging impostor thoughts is a core component of CBT approaches.
Behavioral experiments: Reviews note that testing predictions about likely failure or exposure as a fraud is associated with reduced impostor feelings.
Self-compassion practices: Reviews consistently note that self-compassion approaches address the self-criticism underlying impostor feelings.
Achievement tracking: Reviews note that keeping records of accomplishments provides concrete evidence against impostor beliefs.
Normalizing: Reviews consistently note that understanding impostor syndrome as common (rather than unique personal failure) reduces shame.
Mentorship: Reviews note that mentorship from others in similar positions is associated with reduced impostor feelings.
What the Evidence Does Not Support
There are claims about impostor syndrome that outrun the evidence:
- That any specific intervention universally resolves impostor feelings. Reviews consistently note that responses vary substantially.
- That impostor syndrome indicates actual incompetence. Reviews note that impostor feelings often coexist with actual competence.
- That impostor syndrome is purely an individual issue. Reviews note that environmental and cultural factors contribute.
Common Manifestations
The published research consistently identifies several common ways impostor syndrome manifests:
Overwork: Reviews consistently note that overwork to compensate for perceived inadequacy is a common manifestation.
Avoidance: Reviews note that avoiding challenges (for fear of being exposed) is a common pattern.
Discounting: Reviews consistently note that discounting one’s own accomplishments is a core feature.
Comparison: Reviews note that chronic comparison to others (often upward comparison) is associated with impostor feelings.
Anxiety and stress: Reviews consistently note that impostor feelings are associated with elevated anxiety and stress symptoms.
Considerations for Specific Populations
The published research consistently identifies population-specific considerations:
Women: Reviews note that impostor syndrome has been particularly studied in women, with higher reported rates in some studies, though prevalence patterns are debated.
Racial and ethnic minorities: Reviews consistently note that impostor feelings may have particular dynamics for individuals from underrepresented groups.
High-achieving populations: Reviews note that impostor syndrome is particularly studied in graduate students, medical students, and early-career professionals.
Career transitions: Reviews consistently note that career transitions (promotions, new roles) often trigger or exacerbate impostor feelings.
Imposter syndrome and burnout: Reviews note that impostor feelings and burnout often co-occur and may share some contributing factors.
Common Difficulties
The published research consistently identifies several common difficulties:
Self-perception: Reviews consistently note that impostor feelings distort self-perception, making it difficult to recognize actual competence.
Cumulative effects: Reviews note that chronic impostor feelings can affect career trajectory, relationship satisfaction, and overall wellbeing.
Difficulty seeking support: Reviews consistently note that impostor feelings can make it difficult to seek support or disclose struggles.
Perfectionism reinforcement: Reviews note that perfectionism and impostor feelings often reinforce each other.
Combining Approaches
The published research consistently identifies that impostor syndrome interventions work best when combined with other approaches:
Cognitive + behavioral: Reviews consistently note that combining thought challenging with behavioral experiments addresses both beliefs and behaviors.
Individual + mentorship: Reviews note that combining individual approaches with mentorship from others in similar positions produces better outcomes.
Self-compassion + achievement tracking: Reviews consistently note that combining self-compassion with concrete achievement records addresses both emotional and cognitive components.
When Professional Help Is Needed
Mental health resources consistently recommend professional evaluation when:
- Impostor feelings significantly impair work or life functioning
- Self-help approaches have not been sufficient
- Impostor feelings are accompanied by other mental health concerns (depression, anxiety)
- Impostor feelings are persistent and severe
- Career or life decisions are being substantially affected
Reviews consistently note that therapy, particularly CBT and approaches addressing self-criticism, has documented effectiveness for impostor-related concerns.
Limitations
Some limitations in the published research on impostor syndrome:
- Many studies are correlational; causal claims are limited.
- Most research is in specific populations (high-achieving professionals, students).
- Cultural variations in impostor experiences are not always well represented.
- Individual variation in effective interventions is substantial.
