A CV is supposed to summarize a person’s professional experience, but the line between presenting yourself confidently and exaggerating your qualifications can sometimes become blurred. A job title may sound more senior, responsibilities may be described as achievements, or a minor skill may suddenly appear central to someone’s professional profile.
Deliberately providing false information on a resume can have serious professional consequences. Still, psychology suggests that the motivation behind CV deception is not always as simple as dishonesty. Research on self-presentation, impression management, cognitive load, and self-concept maintenance offers several ways to understand why people may exaggerate their professional histories.
Impression
One useful concept is impression management. The American Psychological Association describes self-presentation as behavior intended to communicate a particular image of oneself to other people. The concept is also closely associated with sociologist Erving Goffman’s work on how people manage the impressions they create during social interactions.
A resume provides an especially strong setting for this behavior. Applicants know they are being evaluated, so they naturally select information that presents them favorably. The problem begins when favorable presentation moves beyond accurate description.
Research by Brent Weiss and Robert Feldman examined deception in job applications and interviews, including whether applicants lied on written applications and whether they did so to meet job requirements. Their work also considered characteristics such as extraversion and self-monitoring.
From a psychological perspective, a CV exaggeration can therefore sometimes reflect an attempt to reduce the perceived gap between “who I am” and “who I believe the employer wants.”
Pressure
Competition can make this process more pronounced. When an applicant believes many similarly qualified candidates are competing for a limited number of positions, exaggerating an accomplishment may seem like a way to remain competitive.
Research by Jamie Guillory and Jeffrey Hancock examined deception in resumes and LinkedIn profiles. Their findings indicated that the desire to create a favorable impression could motivate deception when people’s actual characteristics did not match the image they wanted to communicate. Making professional claims public changed the form of some deceptive behavior but did not eliminate it.
Interview anxiety may also play a role. Research by Deborah Powell, Joshua Bourdage, and Silvia Bonaccio found an association between interview anxiety and deceptive impression-management tactics.
This does not mean anxiety causes people to lie. Rather, pressure to appear competent, concerns about rejection, and uncertainty about one’s qualifications can all become part of the situation in which deceptive self-presentation occurs.
Rationalization
Another interesting explanation comes from self-concept maintenance theory, developed by Nina Mazar, On Amir, and Dan Ariely.
Their research examined how people can benefit from dishonest behavior while continuing to view themselves as honest. The theory suggests that individuals may sometimes rationalize questionable actions or distance themselves from the moral implications of what they have done.
This may help explain why a person can exaggerate a CV while still believing they are fundamentally honest.
For example, someone who “assisted with” a project might describe themselves as having “managed” it. If they played an important role, they may gradually convince themselves that the stronger description is justified.
There is an important difference between presenting genuine experience positively and inventing experience. However, psychological rationalization can make that boundary less obvious to the person making the claim.
Cognitive
Deception can also require additional mental effort.
Psychologist Aldert Vrij and colleagues have studied deception through the cognitive load approach. The basic idea is that lying can require people to construct information, maintain consistency, monitor their behavior, and consider whether another person believes them.
This becomes particularly relevant during job interviews. Someone who has invented or significantly exaggerated an accomplishment may need to remember precisely what appeared on the CV, anticipate questions, and provide details that remain consistent with the original claim.
Research on cognitive load and deception does not mean that mental effort can reliably identify a liar. People can become nervous during interviews for many reasons, and cognitive load varies considerably between individuals.
Still, the additional effort involved in maintaining a fabricated story helps explain why a small CV exaggeration can become more complicated when an interviewer asks detailed questions.
Morality
Albert Bandura’s theory of moral disengagement provides another perspective. Bandura described psychological mechanisms through which people can distance themselves from the moral consequences of their actions.
In the context of resume deception, someone might tell themselves that “everyone exaggerates,” that employers demand unrealistic qualifications, or that they deserve the opportunity regardless of the accuracy of their claims.
These explanations do not make deception acceptable or remove its potential consequences. They illustrate how people can reduce the psychological discomfort that arises when their behavior conflicts with their values.
The ability to rationalize an action can make it easier to repeat.
Selfimage
A CV does more than communicate information to an employer. It can also become a statement about how someone wants to see themselves.
A person who feels unsuccessful, underqualified, or overlooked may be especially motivated to present a stronger professional identity. In that situation, exaggeration may serve two purposes: influencing another person’s judgment and protecting the person’s own sense of competence.
This does not mean every person who lies on a CV has low self-esteem or feels inadequate. There is no single psychological explanation for resume deception. People can have different motivations, including competition, financial pressure, ambition, anxiety, perceived opportunity, or a desire for social approval.
Boundaries
The distinction between confident self-presentation and deception is important.
Accurately describing a genuine contribution in strong language is different from claiming responsibility for work someone never performed. Likewise, emphasizing relevant skills is different from inventing qualifications.
Psychology can help explain why someone crosses that boundary, but explanation should not be confused with justification. False claims can affect employers, colleagues, and other applicants, while also creating practical problems for the person who made them.
Ultimately, people who lie on their CVs cannot be placed into one psychological category. The behavior can involve impression management, competition, anxiety, self-protection, rationalization, and the desire to maintain a positive self-image. The more useful question may therefore be not simply why someone lied, but what the exaggeration was helping them communicate, achieve, or believe about themselves. Knowing that distinction provides a more complete picture of resume deception than simply labeling someone dishonest.
