Impostor syndrome (also known as impostor phenomenon, impostorism, fraud syndrome or the impostor experience) is a psychological pattern in which an individual doubts their skills, talents, or accomplishments and has a persistent internalized fear of being exposed as a "fraud". Despite external evidence of their competence, those experiencing this phenomenon remain convinced that they are frauds and do not deserve all they have achieved. Individuals with impostorism incorrectly attribute their success to luck, or interpret it as a result of deceiving others into thinking they are more intelligent than they perceive themselves to be. Impostor syndrome also occurs in normal human-to-human relationships. Based on this syndrome, continuing doubts about people and individual defense mechanisms are considered difficult to achieve healthy relationships. While early research focused on the prevalence among high-achieving women, impostor syndrome has been recognized to affect both men and women equally.
Impostor syndrome also occurs in the context of mental illness and its treatment. Certain individuals may see themselves as less ill (less depressed, less anxious) than their peers or other mentally ill people, citing their lack of severe symptoms as the indication of no or a minor underlying issue. People with this form often do not seek help for their issues, because they see their problems as not worthy of psychiatric attention.
The term impostor phenomenon was introduced in an article published in 1978, entitled "The Impostor Phenomenon in High Achieving Women: Dynamics and Therapeutic Intervention" by Dr. Pauline R. Clance and Dr. Suzanne A. Imes. Clance and Imes defined impostor phenomenon as an individual experience of self-perceived intellectual phoniness. Impostor experience may be accompanied by anxiety, stress, rumination, or depression.
The researchers investigated the prevalence of this internal experience by interviewing a sample of 150 high-achieving women in the United States. All of the participants had been formally recognized for their professional excellence by colleagues, and had displayed academic achievement through degrees earned and standardized testing scores. Despite the consistent evidence of external validation, these women lacked the internal acknowledgement of their accomplishments. The participants explained how their success was a result of luck, and others simply overestimating their intelligence and abilities. Clance and Imes believed that this mental framework for impostor phenomenon developed from factors such as: gender stereotypes, early family dynamics, culture, and attribution style. The researchers determined that the women who experienced impostor phenomenon showcased symptoms related to depression, generalized anxiety, and low self-confidence.
Measuring impostor phenomenonEdit
The examples and perspective in this section may not represent a worldwide view of the subject. (October 2021)
Impostor phenomenon is studied as a reaction to particular stimuli and events. It is a phenomenon (an experience) that occurs in an individual, not a mental disorder. Impostor phenomenon is not recognized in the DSM or ICD, although both of these classification systems recognize low self-esteem and sense of failure as associated symptoms of depression.
The first scale designated to measure characteristics of impostor phenomenon was designed by Clance in 1985, called the Clance impostor phenomenon scale (CIP). The scale can be used to determine if characteristics of fear are present, and to what extent. The aspects of fear include: fear of evaluation, fear of not continuing success and fear of not being as capable as others.
In her 1985 paper, Clance explained that impostor phenomenon can be distinguished by the following six dimensions:
- The impostor cycle
- The need to be special or the best
- Characteristics of superman/superwoman
- Fear of failure
- Denial of ability and discounting praise
- Feeling fear and guilt about success
Clance noted that the characteristics of these six dimensions may vary. By this model, for an individual to be considered to experience impostorism, at least two of these aspects have to be present. Clance theorised that the most important aspect to understand the manifestation of this experience can be seen through the impostor cycle she created.
Clance and Imes stated in their 1978 article that, based on their clinical experience, impostor phenomenon was less prevalent in men. However, more recent research has mostly found that impostor phenomenon is spread equally among men and women. Research has shown that women commonly face impostor phenomenon in regard to performance. The perception of ability and power is evidenced in out-performing others. For men, impostor phenomenon is often driven by the fear of being unsuccessful, or not good enough. 
It has been estimated that nearly 70% of individuals will experience signs and symptoms of impostor phenomenon at least once in their life. This can be a result of a new academic or professional setting. Research shows that impostor phenomenon is not uncommon for students who enter a new academic environment. Feelings of insecurity can come as a result of an unknown, new environment. This can lead to lower self-confidence and belief in their own abilities.
Impostor phenomenon can occur in other various settings. Some examples include a new environment, academic settings, in the workplace, social interactions, and relationships (platonic or romantic).
In relationships, people with impostorism often feel they do not live up to the expectations of their friends or loved ones. It is common for the individual with impostorism to think that they must have somehow tricked others into liking them and wanting to spend time with them. They experience feelings of being unworthy, or of not deserving the beneficial relationships they possess.
There is empirical evidence that demonstrates the harmful effects of impostor phenomenon in students. Studies have shown that when a student's academic self-concept increases, the symptoms of impostor phenomenon decrease, and vice versa. The worry and emotions the students held, had a direct impact of their performance in the program. Common facets of impostor phenomenon experienced by students include not feeling prepared academically (especially when comparing themselves to classmates), questioning the grounds on which they were accepted into the program,  and perceiving that positive recognition, awards, and good grades stemmed from external factors rather than personal ability or intelligence.
Cokley et al. investigated the impact impostor phenomenon has on students, specifically ethnic minority students. They found that the feelings the students had of being fraudulent resulted in psychological distress. Ethnic minority students often questioned the grounds on which they were accepted into the program. They held the false assumption that they only received their acceptance due to affirmative action—rather than an extraordinary application and qualities they had to offer.
Research has shown that there is a relationship between impostor phenomenon and the following factors:
- Family expectations
- Overprotective parent(s) or legal guardian(s)
- Graduate-level coursework
- Racial identities
- Attribution style
- Low trait self-esteem
- Excessive self-monitoring, with an emphasis on self-worth
The aspects listed are not mutually exclusive. These components are often found to correlate among individuals with impostor phenomenon. It is incorrect to infer that the correlational relationship between these aspects cause the impostor experience.
In individuals with impostor phenomenon, feelings of guilt often result in a fear of success. The following are examples of common notions that lead to feelings of guilt and reinforce the phenomenon.
- The good education they were able to receive
- Being acknowledged by others for success
- Belief that it is not right or fair to be in a better situation than a friend or loved one
- Being referred to as:
- "The smart one"
- "The talented one"
- "The responsible one"
- "The sensitive one"
- "The good one"
- "Our favorite"
In their 1978 paper, Clance and Imes proposed a therapeutic approach they used for their participants or clients with impostor phenomenon. This technique includes a group setting where various individuals meet others who are also living with this experience. The researchers explained that group meetings made a significant impact on their participants. They proposed that it was the realization that they were not the only ones who experienced these feelings. The participants were required to complete various homework assignments as well. In one assignment, participants recalled all of the people they believed they had fooled or tricked in the past. In another take-home task, individuals wrote down the positive feedback they had received. Later, they would have to recall why they received this feedback and what about it made them perceive it in a negative light. In the group sessions, the researchers also had the participants re-frame common thoughts and ideas about performance. An example would be to change: "I might fail this exam" to "I will do well on this exam".
The researchers concluded that simply extracting the self-doubt before an event occurs helps eliminate feelings of impostorism. It was recommended that the individuals struggling with this experience seek support from friends and family. Although impostor phenomenon is not a pathological condition, it is a distorted system of belief about oneself that can have a powerful negative impact on an individual's valuation of their own worth.
Other research on therapeutic approaches for impostorism emphasizes the importance of self-worth. Individuals who live with impostor phenomenon commonly relate self-esteem and self-worth to others. A major aspect of other therapeutic approaches for impostor phenomenon focus on separating the two into completely separate entities.
In a study in 2013, researcher Queena Hoang proposed that intrinsic motivation can decrease the feelings of being a fraud that are common in impostor phenomenon. Hoang also suggested that implementing a mentor program for new or entering students will minimize students' feelings of self-doubt. Having a mentor who has been in the program will help the new students feel supported. This allows for a much smoother and less overwhelming transition.

Studies of college students (Harvey, 1981; Bussotti, 1990; Langford, 1990), college professors (Topping, 1983), and successful professionals (Dingman, 1987) have all failed, however, to reveal any sex differences in impostor feelings, suggesting that males in these populations are just as likely as females to have low expectations of success and to make attributions to non-ability related factors.

Group treatment programs have reported positive results in lowering FOF [fear of failure] (Rajendran & Kaliappan, 1990). The value of groups in countering the so-called impostor phenomenon, in which an individual feels that he or she has succeeded inappropriately and will soon be "found out" to be a fraud, has also been reported (Clance & O'Toole, 1987; J. A. Steinberg, 1986).
