Psychology says people who lie on their CVs or Resumes often have a surprising reason for doing it

A CV is supposed to tell the story of a person's professional life. But sometimes, the story gets polished a little too much. A job title becomes more impressive, responsibilities become achievements, a short internship becomes several months of experience, or a skill that was barely used suddenly appears as a major strength. While deliberate deception on a resume can have serious consequences, psychology suggests that the motivation behind CV lies can be more complicated than simple dishonesty. Research on self-presentation, impression management, cognitive load and self-concept maintenance suggests that some people exaggerate because they are trying to control how others perceive them, protect their self-image or cope with the pressure of competition.

Psychology Says Resume Lies Can Be About Impression Management

One of the most useful concepts for understanding CV exaggeration is impression management. The American Psychological Association defines self-presentation as behavior intended to communicate a particular image of oneself to other people. The idea is strongly associated with sociologist Erving Goffman, whose work compared social interaction to a kind of performance in which people manage the impressions they create.

A resume is almost a perfect environment for this behavior. Applicants know they are being evaluated, so they may emphasize achievements, select flattering descriptions and sometimes cross the line into deception.


Research by Brent Weiss and Robert Feldman specifically examined deception in job applications and interviews. Their study investigated whether applicants lied on written applications, whether they lied to fit job requirements, and whether characteristics such as extraversion and self-monitoring were related to deception.

This means that a CV lie can sometimes function psychologically as an attempt to close the gap between “who I am” and “who I think the employer wants.”

Psychology Says Job Pressure Can Encourage Deceptive Self-Presentation

Competition can make impression management even stronger. If an applicant believes dozens of equally qualified people are competing for one position, exaggerating an achievement may begin to feel like a way of keeping up rather than cheating.

A study by Jamie Guillory and Jeffrey Hancock examined deception in resumes and LinkedIn profiles. Their research found that people's desire to create a favorable impression motivated deception when their actual characteristics did not match the image they wanted to present. Interestingly, making resume claims public changed the type of deception people used but did not eliminate deception altogether.

Interview anxiety can add another layer. Research by Deborah Powell, Joshua Bourdage and Silvia Bonaccio found that interview anxiety was positively associated with deceptive impression-management tactics.

So, for some people, exaggerating a CV may be connected to fear of rejection, perceived inadequacy or intense pressure to appear employable.

Psychology Says Some People Can Convince Themselves Their CV Lie Is Not Really a Lie

This is where the self-concept maintenance theory developed by Nina Mazar, On Amir and Dan Ariely becomes particularly interesting.

Their research suggests that people generally want to benefit from dishonesty while continuing to see themselves as honest. According to the theory, people can sometimes achieve this by mentally redefining questionable behavior or paying less attention to their moral standards. Six experiments supported their theory.

That could explain why someone might think, “I didn't really lie; I just presented my experience in the best possible way.”

There can be a psychological grey area between honest self-promotion and deliberate fabrication. Someone who changes “assisted with a project” into “managed a project” may gradually normalize the exaggeration, particularly if they believe they contributed significantly.

Psychology Says Lying on a CV Creates Cognitive Pressure

Deception also requires mental work. Psychologist Aldert Vrij and colleagues have studied the cognitive load approach to deception, which proposes that lying can require additional cognitive resources because people must construct a story, maintain consistency, monitor their behavior and consider whether the other person believes them. This becomes particularly relevant during interviews.

Someone who has fabricated an accomplishment may have to remember exactly what they claimed, anticipate follow-up questions and construct believable details. Research has found that deceptive responses can involve greater cognitive demands, although cognitive load alone is not a foolproof way of detecting dishonesty.

That is one reason a seemingly simple CV exaggeration can become psychologically complicated once an interviewer starts asking specific questions.

Psychology Says Moral Disengagement Can Make Dishonesty Feel Acceptable

Psychologist Albert Bandura's theory of moral disengagement offers another explanation. Bandura described psychological mechanisms through which people can distance themselves from the moral consequences of their behavior, including minimizing harm, shifting responsibility or reframing questionable actions as acceptable.

Applied cautiously to resumes, a person might tell themselves that “everyone exaggerates,” that the employer is unrealistic about requirements, or that they deserve the opportunity anyway.

That does not make the deception harmless. It simply shows how people can psychologically reduce the discomfort associated with behavior that conflicts with their values.

The Psychology Behind CV Lies Is More Complicated Than “Bad Person”

People who lie on their CVs should not automatically be diagnosed with a particular personality trait or psychological disorder. Resume deception can arise from different combinations of self-presentation motives, competition, anxiety, self-protection, rationalization and perceived opportunity.

The important distinction is between ordinary professional self-promotion and deliberate fabrication. Saying you “contributed to” a successful project when you genuinely did is different from inventing a project that never happened.

Psychology suggests that the most revealing question may not simply be “Why did this person lie?” but “What did the lie allow this person to believe about themselves?”

FAQs

Why do people lie on their resumes?

Psychology suggests several possible motivations, including impression management, competition, interview anxiety, self-protection and the desire to maintain a positive self-image.

Does lying on a CV always mean someone is dishonest?

A deliberate falsehood is dishonest, but the behavior itself does not tell us everything about a person's character. Psychological motives can vary considerably between individuals.
