Personality Tests

Personality tests have become increasingly popular over the past few decades, with many individuals seeking better to understand their personality traits and those of others.

From the well-known Myers-Briggs Type Indicator to the more modern Enneagram, personality tests have become a widely accepted tool for gaining insight into one's personality.

However, despite their popularity, much debate exists about their validity and effectiveness. In this blog post, we will explore the history of personality tests, their creators, cultural biases, and why they may not work as effectively as many believe.

The History of Personality Tests

The origins of personality tests trace back to the late 19th century when psychologists began exploring the concept of personality. One of the first psychologists to develop a personality test was the American psychologist James McKeen Cattell. In the early 1900s, Cattell developed the "mental tests," designed to measure cognitive abilities such as memory and reaction time. While these tests were not designed specifically to measure personality traits, they laid the foundation for later personality tests.

In the 1920s, the American psychologist Carl Jung developed a theory of personality based on four dichotomies: introversion vs. extraversion, intuition vs. sensing, thinking vs. feeling, and judging vs. perceiving.

This theory became the basis for the Myers-Briggs Type Indicator (MBTI), developed in the 1940s by Isabel Briggs Myers and her mother, Katharine Briggs. Myers was a writer, and Briggs was a teacher with a particular interest in the work of Carl Jung.

Together, they created the MBTI based on Jung's theory of personality. The MBTI is one of the most widely used personality tests today, with millions of people taking it each year.

Many other personality tests have been developed in the decades following the MBTI's creation. These tests measure different aspects of personality using different approaches. It is difficult to provide an exact number of different types of personality tests, as the field of personality assessment is constantly evolving, and new tests are being developed. 

Here are ten of the most popular personality tests:

1. Myers-Briggs Type Indicator (MBTI)
2. Big Five Personality Test
3. Minnesota Multiphasic Personality Inventory (MMPI)
4. Enneagram Personality Test
5. DISC Personality Test
6. Rorschach Inkblot Test
7. Thematic Apperception Test (TAT)
8. Projective Drawing Tests
9. Hogan Personality Inventory (HPI)
10. 16 Personality Factor (16PF) Questionnaire

Each of these tests has a unique approach to measuring personality and may focus on different aspects of personality, such as traits, preferences, behaviors, or values. Additionally, many lesser-known personality tests may be used in specific contexts or for particular purposes.

The Myers-Briggs Test

​One of the most well-known personality tests is the Myers-Briggs test, also known as the Myers-Briggs Type Indicator (MBTI). 

Myers and Briggs were interested in understanding people's personalities and how they interacted with one another. They believed that by categorizing people into different personality types, they could better understand how people thought, felt, and behaved.

The Myers-Briggs test focuses on four dichotomies: extraversion vs. introversion, sensing vs. intuition, thinking vs. feeling, and judging vs. perceiving. By answering a series of questions, individuals are put into one of 16 personality types, such as ISTJ (Introverted-Sensing-Thinking-Judging) or ENFP (Extraverted-Intuitive-Feeling-Perceiving).

While the Myers-Briggs test is popular and widely used, it has also been criticized for lacking scientific validity. Some argue that the test needs to be more complex and that people's personalities cannot be neatly categorized into 16 types.

The Big Five

The Big Five Personality Test, also known as the Five-Factor Model, is a widely used personality assessment that measures an individual's personality across five broad dimensions or factors. The five elements are:
​

1. Openness to Experience: Refers to an individual's curiosity, creativity, and openness to new ideas and experiences. People who score high in this factor tend to be imaginative, artistic, and unconventional, while those who score low are more traditional, practical, and conventional.
2. Conscientiousness: Refers to an individual's level of organization, responsibility, and dependability. People who score high in this factor tend to be reliable, hardworking, and disciplined, while those who score low may be more impulsive and disorganized.
3. Extraversion: Refers to an individual's level of sociability, assertiveness, and energy. People who score high in this factor tend to be outgoing, talkative, and confident, while those who score low may be more introverted and reserved.
4. Agreeableness: Refers to an individual's level of empathy, cooperation, and compassion. People who score high in this factor tend to be kind, supportive, and compassionate, while those who score low may be more competitive and critical.
5. Neuroticism: Refers to an individual's level of emotional stability and reactivity. People who score high in this factor tend to be anxious, moody, and sensitive, while those who score low are more emotionally stable and resilient.

​The Big Five Personality Test is based on decades of research and is reliable and valid across cultures and contexts. It is often used in employment settings, as well as in research and clinical settings, to understand the role of personality in mental health and behavior. However, like all personality tests, it has its limitations and should be combined with other assessment tools and contextual information.

The Enneagram

Another personality test that has gained popularity in recent years is the Enneagram. The Enneagram is a personality system that dates back to ancient times but was popularized in the United States in the 1970s and 1980s by authors such as Helen Palmer and Don Richard Riso.

The Enneagram categorizes individuals into nine personality types, each with strengths, weaknesses, and motivations. 

The Enneagram is a personality framework that proposes nine distinct types, each with its own characteristics, motivations, and behavior patterns. The nine Enneagram types are:

1. The Perfectionist - Strives for perfection, is responsible, organized, and self-disciplined, but may also be critical, judgmental, and overly strict with themselves and others.
2. The Helper - Warm and caring, focused on helping and nurturing others, but may also be overly involved, needy, and prone to sacrificing their own needs for others.
3. The Achiever - Ambitious and driven, focused on success and achievement, but may also be overly competitive, image-conscious, and prone to sacrificing their own values and relationships for success.
4. The Individualist - Creative and expressive, focused on authenticity and emotional depth, but may also be overly self-absorbed, moody, and prone to feeling misunderstood or disconnected from others.
5. The Investigator - Analytical and curious, focused on gathering knowledge and understanding, but may also be emotionally detached, secretive, and prone to isolating themselves from others.
6. The Loyalist - Dependable and loyal, focused on security and stability, but may also be anxious, indecisive, and prone to seeking reassurance and support from others.
7. The Enthusiast - Energetic and optimistic, focused on new experiences and possibilities, but may also be distractible, impulsive, and prone to avoiding difficult emotions and commitments.
8. The Challenger - Assertive and confident, focused on control and protection, but may also be confrontational, domineering, and prone to disregarding the needs and feelings of others.
9. The Peacemaker - Easygoing and conciliatory, focused on harmony and unity, but may also be passive, indecisive, and prone to avoiding conflict and their own needs.

​Like the Myers-Briggs test, the Enneagram has its critics, some argue that the system is too vague and that people can identify with aspects of multiple types.

What About Cultural Biases in Personality Tests?

​Personality tests can have cultural implications and may be biased toward the culture of the individuals who created them. This is because personality tests are created within a particular cultural and historical context, and the concepts and constructs used to measure personality may reflect that culture's values, beliefs, and norms.

For example, some personality tests may prioritize individualism, achievement, and self-expression, typical values in Western cultures, while overlooking collectivism, harmony, and conformity, which are more emphasized in Eastern cultures. This can lead to a potential bias in the assessment of individuals from different cultural backgrounds, and the results may not accurately reflect their unique personality traits and characteristics.

Furthermore, the interpretation and use of personality test results can also be influenced by cultural factors. For instance, some cultures may view certain traits, such as assertiveness or emotional expressiveness, as positive and desirable, while others may view them as negative or inappropriate. This can affect how individuals and organizations interpret and use personality test results, potentially leading to misunderstandings and misapplications of the information.

Therefore, it's important to consider the cultural context and potential biases of personality tests when interpreting and using the results. This can be done by ensuring the test has been validated across different cultures and languages and using culturally sensitive interpretation methods. 

Should You Rely on Personality Tests?

​Despite the criticisms of personality tests, many people still rely on them to better understand themselves and others. For example, personality tests give individuals insights into their strengths and weaknesses and help them identify potential career paths and relationships that may be a good fit.

Personality tests can also be a source of validation for individuals. By identifying with a specific personality type, people may feel they are part of a community of like-minded individuals with similar struggles and strengths.

While personality tests can be helpful, they also have their limitations. One of the main criticisms of personality tests is that they are based on self-reporting. In other words, individuals answer questions about themselves, which may only sometimes be accurate.

Another issue with personality tests is that they assume that people's personalities are stable and unchanging. However, research has shown that people's personalities can change over time due to life experiences and personal growth.

Finally, personality tests may reinforce stereotypes and limit people's potential. By categorizing individuals into specific personality types, personality tests may overlook the complexity and nuance of human behavior.

​In conclusion, personality tests have been popularized over the years and continue to be used by many individuals to gain insight into themselves and others. From the Myers-Briggs test to the Enneagram, these tests have their strengths and weaknesses. While they can provide people with validation, potential career paths, and insights into their strengths and weaknesses, they should also be approached with a critical eye, as they are based on self-reporting and assume that personalities are stable and unchanging. Ultimately, it's up to each individual to decide whether or not they find value in personality tests. Still, it's important to remember that they are not the be-all and end-all when it comes to understanding ourselves and those around us.
