The Myers-Briggs Type Indicator (MBTI) is one of the most popular and frequently administered psychological tests. Despite strong criticism from academic circles regarding its validity, the MBTI has many advocates in practitioner communities.

The MBTI is copyrighted and has not been placed in the public domain. You will have to pay for taking the official version of the MBTI unless you are a student or employee of an organization that has underwritten the costs. If not, you can visit the Meyer & Briggs Foundation at the link below and make the appropriate financial arrangements.

The Big Five personality measure, in contrast, has a much stronger reputation in the scientific community, and you may take a public domain version for free.

Clones of the MBTI are available all over the Internet and may be taken without charge. Hidden costs, however, include receiving personal feedback lacking any scientific basis and losing anonymity to companies who will solicit your business. Most MBTI clones are worthless except for their entertainment value; you should never make a decision on the basis of their results.

For educational purposes, we have placed a link below to a simulation of the MBTI experience; it is offered by a commercial organization in partnership with the Association for Psychological Type International. Although many people complete this simulation as a substitute for the MBTI, we urge you to be cautious. There are no assurances that your results will correspond to what you would receive after taking the official MBTI. Moreover, typing in a functional email address will likely cause unsolicited advertisements. On the other hand, you will obtain a working knowledge of the MBTI system and discover how your own personality might be described in MBTI terms.
