Can Personality Be Analyzed From IQ Test Scores?

IQ Test Scores

Intelligence Quotient (IQ) is a measure of intelligence that’s often employed in educational and clinical settings. Unfortunately, it may not be the only indicator and may not accurately reflect everyone’s capabilities.

IQ tests measure specific skills across cognitive domains, such as verbal comprehension, spatial reasoning and fluid reasoning. These abilities are closely associated with one another.


Psychometrics is a branch of science that measures psychological constructs. It relies on methods rooted in statistics, data theory and econometrics for accurate measurements.

Many employers utilize psychometric tests to evaluate job candidates before making hiring decisions. These assessments help pinpoint candidates’ strengths and weaknesses, social traits, motivations, and attitudes.

The IQ test industry is a multibillion-dollar business, and both test providers and corporate users rely on this testing to assess candidate qualifications. These IQ test can measure academic achievement, resilience in stressful situations, as well as personality traits.

However, it can be challenging to gauge someone’s personality from their IQ test scores alone. This is because people can often be swayed by an interviewer’s prejudice and references.

The Big Five model

The Big Five model is a widely-used personality assessment and an effective tool for understanding people’s behavior. It centers on the idea that there are five major personality traits: extraversion, agreeableness, conscientiousness, openness to experience and neuroticism.

The Big Five model has been extensively validated and used to help researchers better comprehend and analyze personality. It is even employed by psychologists and marketers when assessing client personalities.

There are various assessments used to measure these traits, such as the NEO PI-R and NEO-FFI. Both tests are commercially controlled and have undergone multiple revisions over time.

Studies have demonstrated that the Big Five traits are highly predictive of IQ test scores, particularly among younger individuals. Furthermore, these traits have been connected to various health issues like depression and psychiatric disorders.

Thematic Apperception Test

There are various personality tests that can be employed to assess someone’s disposition. One popular choice is Thematic Apperception Test (TAT).

Morgan and Murray developed this projective psychological test in 1935 as a means of assessing personality, values, and attitudes.

The TAT is based on the idea that people reveal aspects of themselves when responding to uncertain stimuli. This could be because these stimuli elicit hidden emotions, thoughts or beliefs.

These tests are a unique type of personality assessment and often employed for psychological assessments. Furthermore, they may be combined with other personality assessments to give an insightful portrait of someone’s character traits and potential.

Myers-Briggs Type Indicator

The Myers-Briggs Type Indicator (MBTI) is a popular personality test widely used by college counseling offices and business departments to determine an individual’s preferred communication styles, task approach and career interests.

The MBTI test was created based on Carl Jung’s theories. Research team Katharine Briggs and Isabel Briggs Meyers believed that by understanding personality types, individuals could make better career choices.

However, some scientists have expressed dissatisfaction with the Myers-Briggs test. They contend that personality traits cannot be neatly classified into 16 boxes.

Contrary to popular belief, personality traits do not follow a Gaussian distribution. Most individuals fall somewhere in the middle of each trait. While there may be some outliers, these are not representative of all individuals.
