Psychometric assessments are increasingly used by employers to understand candidates beyond their resumes and interview performance. They can measure personality traits, behavioral preferences, cognitive abilities, motivation, and other job-related characteristics. But an important question remains: can candidates fake a psychometric test?

The short answer is yes, candidates can intentionally distort some responses, particularly when they believe the assessment will influence whether they receive a job offer. However, research also shows that this does not mean psychometric assessments are automatically unreliable or unsuitable for recruitment. The design, validity, administration, and interpretation of the assessment all matter.

Why Would Candidates Fake a Psychometric Test?

Candidates generally want to present themselves positively during a hiring process. When completing a personality assessment for a job, an applicant may believe that certain answers will make them appear more dependable, motivated, confident, cooperative, or productive.

For example, if a question asks whether someone always meets deadlines, a candidate who wants to appear highly conscientious may be tempted to select the most favorable response.

Research in personnel selection recognizes this phenomenon as faking, meaning intentional distortion of responses to create a more favorable impression. The American Psychological Association's principles for personnel selection procedures specifically identify applicant faking as a potential issue with self-report measures of personality and other noncognitive characteristics.

Can Candidates Really Manipulate Personality Assessments?

Yes, but the extent to which they can influence results depends heavily on how the assessment is designed.

Some traditional personality questions may make the desired answer relatively obvious. If candidates can easily identify which response appears most attractive to an employer, they may attempt to select that answer.

Research discussed by the American Psychological Association has found that applicants can fake noncognitive assessments when they understand which responses are viewed favorably. Researchers have also explored assessment designs intended to make the desirable response less obvious.

This is why well-designed assessments should not simply ask candidates to select obviously positive statements.

Does Faking Make Psychometric Tests Useless?

No.

The fact that candidates can sometimes distort responses does not mean that every assessment result is invalid. Fred Oswald, an industrial-organizational psychologist, explains that people can lie on personality tests, but the existence of some faking does not mean personality assessments should simply be discarded.

Instead, employers should consider psychometric assessments as one component of a broader selection process.

A candidate's assessment results can be considered alongside:

  • Relevant work experience
  • Technical skills
  • Work samples
  • Structured interviews
  • Cognitive ability
  • Situational judgment
  • References, where appropriate
  • Other job-relevant evidence

This provides a broader picture than relying on one assessment score.

How Modern Assessments Can Reduce Faking

Assessment developers use different approaches to reduce the impact of socially desirable responding.

1. Forced-Choice Questions

Instead of asking candidates to rate themselves against a single statement, some assessments ask them to choose between statements that are both desirable but represent different characteristics.

This can make it more difficult for candidates to identify a single obviously “correct” answer. The APA has highlighted research into forced-choice and other assessment formats as part of the broader study of susceptibility to faking.

2. Less Obvious Assessment Design

Candidates are more likely to manipulate answers when they can easily determine what the test is measuring.

Well-designed assessments can use carefully constructed questions and scoring methods that make the intended trait less transparent.

Research discussed by the APA has also examined computer-based and gamified approaches that may make it harder for candidates to identify exactly which characteristics are being assessed.

3. Consistency Checks

Assessment systems can analyze response patterns for unusual or inconsistent behavior.

These checks should not automatically label someone as dishonest. Instead, unusual patterns can indicate that results should be interpreted carefully.

4. Combining Multiple Assessment Methods

Using psychometric assessments alongside other selection methods can reduce dependence on any single source of information.

For example, an employer could combine a personality assessment with a skills test, structured interview, and realistic work sample.

What Employers Should Look for in a Psychometric Test

When choosing an assessment, employers should look beyond whether it has an attractive interface or produces a simple candidate score.

A useful assessment should have evidence supporting its:

Reliability: Does it measure the intended characteristics consistently?

Validity: Does the assessment actually provide useful information about the job-related characteristic it claims to measure?

Fairness: Is the assessment appropriate for the population being assessed and used in a fair manner?

The APA describes reliability, validity, and fairness as important principles in workplace assessment.

Employers should also ensure that the characteristics being measured are genuinely relevant to the position.

Should Employers Tell Candidates About the Assessment?

Clear instructions can improve the candidate experience and encourage applicants to approach assessments seriously.

Candidates should understand why an assessment is being used, what the process involves, and how their information will be handled.

Employers should avoid creating an assessment process that feels like a hidden psychological evaluation. Transparency can help establish trust while still allowing organizations to gather useful job-related information.

Psychometric Assessments and Predictive Hiring

Psychometric assessments become particularly useful when they are connected to a clearly defined job profile.

Instead of asking whether a candidate has a generally “good” personality, recruiters can identify the characteristics that are relevant to success in a particular role.

For example, a customer-facing position may place greater importance on communication and interpersonal characteristics, while a role involving detailed analytical work may require different behavioral and cognitive characteristics.

Research supports the broader principle that selection assessments should be connected to the characteristics and requirements that matter for job performance.

How SmoothHiring Can Support Candidate Assessment

SmoothHiring combines candidate evaluation with predictive hiring and behavioral assessment to help organizations look beyond resumes and interviews.

A structured assessment approach can help recruiters compare candidates against defined job requirements and identify areas that deserve further evaluation.

For high-volume recruitment, this can also help organizations apply consistent assessment criteria across a large candidate pool.

The goal should not be to predict a candidate's entire future from one test. Instead, assessment results can provide another useful source of evidence for a broader hiring decision.

Best Practices to Reduce the Impact of Faking

Employers can improve the quality of psychometric testing by following several practices:

  • Choose validated assessments designed for employment use.
  • Select tests that measure job-relevant characteristics.
  • Use consistent assessment procedures.
  • Avoid relying on one test score as the sole hiring criterion.
  • Combine psychometric results with skills and structured interviews.
  • Monitor unusual response patterns without automatically assuming dishonesty.
  • Review assessment effectiveness against actual employee outcomes.
  • Protect candidate data and communicate the purpose of testing clearly.

Conclusion

So, can candidates fake a psychometric test? Yes. Candidates may intentionally present themselves in a more favorable way, particularly when they know an assessment affects a hiring decision. Research recognizes faking as a legitimate consideration when using self-report assessments in personnel selection.

However, faking does not make psychometric assessments useless. Carefully designed assessments, appropriate scoring methods, and multiple sources of candidate evidence can help employers obtain more meaningful information.

The most effective approach is to treat psychometric testing as one part of a structured recruitment process, rather than as a standalone decision-maker. When assessments are reliable, valid, job-relevant, and combined with other evidence, they can help recruiters make more informed and consistent hiring decisions.
