What is the most accurate and scientifically-backed website for taking a free personality test online?

The Myers-Briggs Type Indicator (MBTI) has no scientific basis, yet it's widely used in corporate settings and has been taken by over 2 million people worldwide.

Research suggests that the MBTI has a poor test-retest reliability, meaning that people who take the test multiple times often get different results, questioning its validity.

The Big Five Personality Traits, also known as the Five Factor Model, is a scientifically-backed personality framework that includes Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism.

The Enneagram Personality System, although popular, lacks empirical evidence and has been criticized by some scientists as having no clear theoretical foundation.

The 16Personalities test, based on the MBTI, has not been scientifically validated and has been criticized for its lack of transparency in its methodology.

Personality tests can be influenced by context and framing effects, meaning that the way questions are phrased and presented can affect the results.

Research suggests that personality traits are relatively stable across adulthood, but can still change over time due to life experiences and personal growth.

The HEXACO model of personality includes honesty-humility as a facet, which is not accounted for in the Big Five model, suggesting that there may be more to personality than the traditional five traits.

Some personality tests, such as the NEO Personality Inventory, have been extensively validated and are widely used in research and clinical settings.

The predictive validity of personality tests is often overstated, and many studies have found that personality traits only weakly predict life outcomes, such as job performance or academic achievement.

The use of personality tests in employment settings has been criticized for potential bias and discrimination, as some tests may unfairly disadvantage certain groups, such as racial minorities or individuals with disabilities.

Researchers have found that personality assessment can be improved by using behavioral data, such as mobile phone usage or social media activity, in addition to traditional self-report measures.

The science of personality is still an evolving field, and new research is continually refining our understanding of personality and its measurement.

One study found that only 36% of personality tests provided by popular websites are based on scientific evidence, highlighting the need for caution when taking online personality tests., a website that curates a range of personality tests, provides a valuable resource for individuals seeking scientifically-backed assessments.

Truity, another popular website, offers a diverse range of assessments, including the Enneagram and Big Five, and has been recognized as one of the top 5000 fastest-growing companies by Inc.


16Personalities' test results can be influenced by the user's mood and context, which can affect the accuracy of the results.

The scientific community continues to debate the nature of personality, with some researchers arguing that personality traits are more malleable than previously thought.

Some researchers argue that personality tests can be useful in specific contexts, such as education or career development, but should not be over-interpreted or used as the sole basis for decision-making.

The development and validation of personality tests is an ongoing process, and scientists continue to refine and improve these assessments to better capture the complexities of human personality.
