Why choose TraitLab vs the MBTI?

What is the MTBI?

The Myers-Briggs Type Indicator, also known as the MBTI, is a widely-popular personality measure based on a loose interpretation of the theories of Swiss psychiatrist Carl Jung, as described in Psychological Types (1921).

According to the theory behind the MBTI, people differ in their orientation to the external vs. inner world and their preferences for cognitive functions used to receive and process information. The MBTI claims to assess these orientations and preferences, which classify individuals into one of 16 different personality types.

The MBTI is typically used in corporate environments and other professional settings. The MTBI and Myers-Briggs Type Indicator are registered trademarks of the Myers & Briggs Foundation.

How is TraitLab different?

TraitLab provides a comprehensive analysis of personality traits, career interests, interpersonal style, and character strengths based on peer-reviewed, publically accessible research.

The TraitLab system

TraitLab gradually combines information from hundreds of highly specific traits to build a more complete personality profile. Your TraitLab profile contains the same information from popular personality type measures like the MBTI and much, much more.

Anyone can get started with TraitLab right now by creating a free account.

How it works

You are more complex than four letters

Nobody fits into a single type. TraitLab measures over 80 different dimensions to identify your pattern of personality traits, career interests, interpersonal style, and character strengths.

While millions of people have similar results from the Myers-Briggs Type Indicator (MBTI), your TraitLab results are unique to you and you alone.

Prioritize with your strengths in mind

TraitLab estimates your unique ranking of character strengths, clarifying where you naturally feel engaged and enthusiastic, and then suggests ways to use your strengths in everyday life.

Unlike the Myers-Briggs Type Indicator (MBTI), TraitLab goes beyond your general personality. Instead, TraitLab explains how your personality translates into character strengths, which you can leverage in your personal and professional life.

TraitLab includes a detailed analysis of your character strengths, which you can use in several areas of life, while the Myers-Briggs Type Indicator (MBTI) classifies people into broad types without any specific guidance around individual strengths.

Explore new career paths

Myers-Briggs Type Indicator (MBTI) types do not easily map to particular careers or occupational areas, making it difficult to use your personality type to compare and contrast potential career paths.

With TraitLab, you can easily compare your profile across hundreds of occupations, learn about your relative strengths in each of them, and better understand the trade-offs and opportunities behind different career paths.

Identify your interpersonal style

Personality "types" tend to be very broad. As a result, two people with identical types from the Myers-Briggs Type Indicator (MBTI) may still have dramatically different styles of interacting socially.

TraitLab includes a far more detailed analysis of your interpersonal style, which describes your natural tendencies in social interactions, as well as associated opportunities and challenges.

TraitLab describes your interpersonal style and the opportunities and challenges that come along with it, while your type from the Myers-Briggs Type Indicator (MBTI) does not describe interpersonal patterns beyond your given type.

Frequently asked questions

How is TraitLab different from other personality assessments?

Most online assessments are not based on real published research, so you can't connect your results to useful information about habits, career choices, relationships, and other practical aspects of your life.

TraitLab uses assessments and concepts from actual scientific research, then makes it easy to see how your results relate to important life areas.

Who made TraitLab?

TraitLab was created by me, Greg Park, Ph.D. Hi!

Before starting TraitLab, I spent years publishing research findings as a Ph.D. and postdoctoral researcher in the areas of personality and psychological measurement. I've always been fascinated by the field of personality psychology and how it can help us understand ourselves and each other.

I made TraitLab to make it easier for you to find reliable, valid, and scientifically-supported personality assessments.

Is TraitLab right for me?

Are you comfortable with investing about an hour to understand yourself better? Do you care about scientific validity? Do you like to get into details and data?

If you answered yes to these questions, then you'll probably love TraitLab. I made it for people like me — people looking for a very detailed, comprehensive picture of their personality, strengths, and interests, backed by scientific research.

But if you are looking for a quick and fun personality quiz, TraitLab is probably not the best fit for you.

How long is the TraitLab test?

Most people will start seeing their first results after about 10 minutes (about 100 questions).

If you want to see every possible result from TraitLab, the full assessment can take anywhere from 30-60 minutes. However, you can always save your progress and take the assessment across several sittings.

How many questions are there in TraitLab?

There are over 700 potential questions currently in TraitLab, but you'll begin seeing results after the first 100 questions.

New questions are added regularly, but most questions are optional and only needed for advanced analyses.

How much does TraitLab cost?

It's free to create an account on TraitLab and learn quite a bit about your personality.

For more advanced analyses of your traits, strengths, and interests, you can upgrade to TraitLab Plus for $49.

Can I share my results with someone else?

Absolutely! If you want to share and compare your results with anyone, you can simply share your public profile.

For example, here's my own public profile here at TraitLab.
