41q
Generalities
41q is a free online personality test that the publisher says was devised from Jung’s personality theory and the four types of the Myers-Briggs.
The publisher further asserts that the calculation of the relationship compatibility match is inspired by the theory of Socionics and Antoni Kepinski’s theory of information metabolism. A Swedish company publishes the survey.
Assessment
The assessment is a forced-choice questionnaire. Participants are asked to check 41 propositions that are more or less true to them. It takes around 5 minutes to complete.
The results are a report and an eight-digit code that participants can enter into the application to find their unique formula, compatibility, or match with another person’s code.
Usage
The publisher proposes the test free for self-awareness, improved relationships, career guidance, personal growth, and team building.
Comments
The limitations are the same as for the MBTI on which the assessment is based.
An API for 41q is available from GitHub. The API access is a paid service based on the number of monthly queries.
