Open Jungian Type Scales 2.1 results

This page will review your scores, provide a sketch of the personality type they indicate, and then provide information about the accuracy and reliability of the OJTS.

Scale scores

The OJTS measures four pairs of scales, each scale ranging from 0 to 36. In the theory of Myers and Briggs the pairs are considered to be dichotomous preferences, much like the way people have a preference for handedness. And test scores only indicate preferece, not strength (i.e. if someone were to score equally for both that would just mean the test failed to detect their preference, not that they don't have one). The best match preference for each dichotomy based on your scores are highlighted in red.


The natures of these four dichotomies are usually descibed in very metaphorical language. The four pairs are summarized by Myers and Briggs in their book Gifts Differing: Understanding Personality Type along these lines:

This is not that clear though, I would reccomend looking at the OJTS documentation for what questions used to measure each dichotomy for the best understanding.

Psychological type

The four preferences are combined into a four letter code, refered to as psychological type. If our scores are accurate, your type is INTP. The description of this type from Wikipedia is in the box below.

INTPs are quiet, thoughtful, analytical individuals who tend to spend long periods of time on their own, working through problems and forming solutions. They are curious about systems and how things work. Consequently, they are frequently found in careers such as science, philosophy, law, and architecture. INTPs tend to be less at ease in social situations or in the "caring professions", although they enjoy the company of those who share their interests. They prize autonomy in themselves and others. They generally balk at attempts by others to convince them to change. They also tend to be impatient with the bureaucracy, rigid hierarchies, and the politics prevalent in many professions. INTPs have little regard for titles and badges, which they often consider to be unjustified. INTPs usually come to distrust authority as hindering the uptake of novel ideas and the search for knowledge. INTPs accept ideas based on merit, rather than tradition or authority. They have little patience for social customs that seem illogical or that serve as obstacles for pursuing ideas and knowledge. This may place them at odds with people who have an SJ preference, since SJs tend to defer to authority, tradition, and what the rest of the group is doing. INTPs prefer to work informally with others as equals.

INTPs organize their understanding of any topic by articulating principles, and they are especially drawn to theoretical constructs. Having articulated these principles for themselves, they can demonstrate remarkable skill in explaining complex ideas to others in simple terms, especially in writing. On the other hand, their ability to grasp complexity may also lead them to provide overly detailed explanations of simple ideas, and listeners may judge that the INTP makes things more difficult than they need to be. To the INTPs' mind, they are presenting all the relevant information or trying to crystallize the concept as clearly as possible.

Given their independent nature, INTPs may prefer working alone to leading or following in a group. During interactions with others, if INTPs are focused on gathering information, they may seem oblivious, aloof, or even rebellious—when in fact they are concentrating on listening and understanding. However, INTPs' extraverted intuition often gives them a quick wit, especially with language. They may defuse tension through comical observations and references. They can be charming, even in their quiet reserve, and are sometimes surprised by the high esteem in which their friends and colleagues hold them.

INTPs are driven to fully understand a discussion from all relevant angles. Their impatience with seemingly indefensible ideas can make them particularly devastating at debate. When INTPs feel insulted, they may respond with sudden, cutting criticism. After such an incident, INTPs are likely to be as bewildered as the recipient. They have broken the rules of debate and exposed their raw emotions. To INTPs, this is the crux of the problem: improperly handled emotions, INTPs believe, can only harm. While INTPs experience emotions as an important part of their internal lives, and sometimes share their emotions with others, INTPs nevertheless believe that emotions must not play a role in logical discussions, or be expressed in a way that would put themselves at disadvantage.

According to Keirsey, based on behavioral characteristics, notable Architects might include Albert Einstein, Charles Darwin, and Thomas Jefferson.

Accuracy of the OJTS

The OJTS was designed to predict psychological type in individuals who already claimed to already know their type. Over 2,900 different questions were tested and the ones that differentiated between self reported types the most were retained for the OJTS. This effort was started in 2014 and finished in 2020, see the documentation for all the details. This contrasts with how almost all other tests were developed: by one psychological type "expert" sitting down and coming up with what questions they thought were good.
