Here's a short history of personality tests before we get to the list...
The history of personality testing...
In around the year 460BC, the Hippocrates suggested that humans had a 'persona' - a personality that was comprised of four distinct temperaments. He suggested that whichever fluid was more dominant in a person determined their 'humour', and thus their different personality.
In 1879, Withelm Wundt became, not only the 'Father of Psychology', but became the first person to draw a clear distinction between the human body and a human personality theory.
The rise of the psychodynamic approach in the late 1800's lead to a drastic change in the way that we viewed and understood personality in social situations with a group of people.
The founder of the Psychodynamic approach, Sigmund Freud, suggested that our personality was a lot more complexed than originally suggested and that our behavior, and personality, is driven by our innate drives and needs.
Carl Jung, proposed that there are only four human personality preferences: sensing, intuition, thinking and feeling, and that these influence our personality. The 1900's lead to an increased interest in personality testing, assessments, and typing, especially in the workplace.
Woolworth personal data sheet was the first modern personality test to be invented; it was used by the united states American army to detect which recruits would be susceptible to shell shock.
Since the 1900's personality testing, personality assessments, and theories of human personality has skyrocketed. People are now very familiar with personality quizzes such as the Myers-Briggs test, 16 personalities, big five and various iq tests.
Now without further ado...
The Best Personality Tests In Ranking Order

Myers-Briggs Type Indicator
The Myers-Briggs Type Indicator (MBTI) was introduced by Katharine Cook Briggs and her daughter, Isabel Briggs Myers, in the 1940s.
The test is based upon an earlier theory that was introduced by Carl Jung - a theory that humans experience the world using four psychological functions: sensation, intuition, feeling and thinking.
The MBTI measures whether an individual is extroverted or introverted, whether they have a sensing preference or an intuitive preference when it comes to processing information, whether they prefer to make decisions by thinking or feeling and whether they have a judging or perceiving preference about how they do things.
The results from the questionnaire then place the person onto one of 16 personalities, each has their own strengths and weaknesses, such as the ENJF personality type.
The MBTI can be used for individual development, employee development, team development, team productivity and to increase team effectiveness.
The questionnaire consists of 93 forced-choice questions, where the participant matches a word with a statement.
The pricing of this tool will vary depending on what type of Myer-briggs type indicator you buy and where you purchase it from.
Eysenck Personality Inventory
The Eysenck Personality Inventory measures personality on two independent dimensions: extroversion versus introversion and neuroticism versus stability.
The questionnaire generates three scores, the 'E' score which indicates how extroverted you are, an 'N' score which measures how neurotic you are, and a 'lie' score, which measures how much you have lied on the questionnaire to be socially desirable.
The full questionnaire consists of 100 yes/no questions and takes 20-35 minutes to complete.
There is also a shorted questionnaire that consists of 57 yes/no questions, that takes only 10-25 minutes to complete.

However, it can also be used in occupational settings to screen candidate - especially to measure the psychological stability of those in high-risk professions, such as the police force, pilots or the army.
The MMPI has been changed and revised over the years, but the most recent version, the MMPI-2, contains 567 true-false questions and takes between a 60 to 90 minutes to complete.
There is a shorter version, the MMPI-2-RF, which contains 338 questions and takes around 30-50 minutes to complete. -More detailed information can be found here.

Keirsey Temperament Sorter
David Keirsey expanded on the temperament theory that was originally introduced by Hippocrates (outlined in the introduction to this blog).
The questionnaire measures personality across four temperaments: artisan, guardian, idealist and rational.
Keirsey then divided these four temperaments intro two categories (roles), each with two types (role variants) - these 16 personality types correlate with the 16 personality types that are outlined in the Myers-Briggs Personality Type inventory.
The test is very popular in the US and have even been used by the Bank of America and the US air force.
There is little information on the nature, length or pricing of the questionnaire online.
Introduced by Don Lowry in 1978, the True Colours test was designed to measure four basic learning styles: independent thinkers, pragmatic planners, action-oriented, people-oriented.
Each of the learning styles represents a colour (hence the name), and each person can be a unique blend of all of four colours.
The results from this assessment can be used to help mitigate potential conflict between individuals by understanding each others characteristics.
Little information is available online but a quick test can be taken for free to get a rough idea of what your true colours may be.
The Caliper profile is an employee and applicant assessment instrument that measures an individuals job performance potential and can find out which person is best suited for the job based on their intrinsic motivation.
The results from these profiles are often used for hiring, employee development, team improvement, talent alignment, succession planing, employee engagement and to increase productivity.
The Caliper Profile consists of 180 multiple choice questions and can sometimes take as long as 2 hours to complete.
Rorschach Inkblot Test
Invented by Hermann Rorschach in the 1960s, the inkblot test is perhaps one of the most unique and 'quirky' personality tests out there.
Typically done in person, the inkblot test is an assessment where an examiner presents the participant with an inkblot, and the participant tells the examiner what they see.
The participant perception of the inkblot is then analysed and interpreted by a psychologist using complex algorithms - this is then says things about the participants personality.
The test is designed to deter the psychological state of an individual and can be used on children from the age of 5, all the way to adults.
Traditionally the test is done in person with an examiner, but you can do a free shortened test online.
Developed by Leopold Szondi in 1935, the Szondi test is based on the systematic drive theory and the dimensional model of personality.
During the test, participants are shown a series of facial photographs which represent people who have been classified as homosexual, sadist, epileptic, hysteric, catatonic, paranoid, depressive and a maniac.
The participants then pick the most appealing and most repulsive pictures, and it is believe that the one deemed most 'repulsive' displays something about our personality as we have formed an aversion, or become repressed to that psychological state.
This traditional test is not really used that much anymore, but you can still complete some free versions online such as this one.
Frequently asked questions:
Can I use these tests in the workplace?
In recent years there has been an increase in the use of personality testing in the workplace and there is a growing amount of research to support its use.
Studies have found that employees who fit well in an organization are more satisfied and more likely to stay within the organization - and whats the most effective way to ensure an employee fits into an organization?
You got it, personality testing!
Richard Branson also once quoted that 'company knowledge and job-specific skills can be learned, but you can't train a personality', so in order to get the most effective employees for your team you could incorporate personality testing at some point.
For personality tools, specifically designed to measure personality in the workplace, check out this post I wrote a few months ago.
However, there are dangers of using personality testing in the workplace, especially for hiring. For more insight into the potential problems of using personality testing in the workplace, give this article a read.
These seem old, are there modern day alternatives?
Granted, some of these tests are fairly old and perhaps slightly outdated, such as the inkblot testing.
However, the tests such as the Myers Briggs Type Indicator, DiSC and the assessments introduced by Hogan and Hogan are pretty modern and have been shown to have good reliability and validity in recent years.
However, if you really do want to take a step into the modern day and explore new alternatives, there has been an increase in online tools that combine many personality tests in a fun and insightful way.
Many of these tests are aimed at organizations, but some could be used for personal use.
Can I use these on my children to predict their success at school?
There are studies to suggest that a child's personality will predict school success.
For example, studies have suggested that children who are highly conscientious will be more successful in school due to their ability to be organized, meet deadlines, comply with rules and work hard.
There is also research to suggest that the personality traits we display can influence our career choice and success.
However, as with almost all things in psychology, there is a huge debate as to whether anything humans do is due to nature or nurture - even our personality, is it influenced by our environment or our genetics?
So, it is possible, that when wondering about your child's school and future life success, their personality will not be the only influencing factor, their success can be greatly influenced by how you, their parent, raise them.
Will knowing the results of my personality tests benefit me in life?
Yes, in many ways knowing and understanding your personality can benefit you in life.
Firstly, understanding your personality will help you at work as it can help you decide what career path to chose, how to develop this career and what sort jobs to apply for based on your personality (and how to behave in these interviews).
Understanding your own, unique, personality will also aid you in personal development - you can understand how you best interact with others, how you need to relax, what motivates you and how you handle stress or pressure.
You are the only person in the world with your personality; you should really invest in learning to understand it.
However, it is important to remember that personality testing does force people into categories or scales; so, although understanding your personality in psychological terminology is great, do be mindful that it may not always be completely accurate.
What do I do if I don't get the result I wanted?
Then you are not who you want to be, and there's nothing wrong with that either.
Learn to understand your own strengths and weakness and learn how you can use these to your advantage.
Say, if you so desperately wanted to be an extrovert so you could be 'popular' or accepted by others, but it turns out that you're actually massively introverted, then you must learn to understand what your needs and wants actually are to be satisfied.
You will most likely not want to be surrounded by people, you will prefer solo work and you will prefer to unwind by being alone - and there's nothing wrong with that either, both extroverts and introverts can be popular, successful and satisfied.
That wraps up 2019 edition of the ranked list of best personality tests.
I hope you find the test you were looking for ;)
