If You Are Using the MBTI and the Platform, the Cost, or the Participant Experience Is Getting in the Way of Your Work, Here Is What Changes

How Type Discovery delivers the same 16 Jungian psychological types with a more accurate instrument, a better participant experience, and a platform built for practitioner-led development work.

You built your practice around psychological type because it works. The four-letter code gives people a neutral, non-judgmental language for differences that would otherwise feel personal. It supports self-awareness, improves communication, and creates a shared vocabulary that teams can use long after the workshop ends.

The question is not whether to use psychological type. The question is whether your current instrument and platform are supporting that work as well as they could.

Switching from the MBTI

The MBTI is the most recognized name in psychological type, and practitioners who use it have good reasons for doing so. The research base is substantial, the organizational credibility is established, and many practitioners have invested significantly in MBTI training and certification.

Over the past several years, however, many MBTI practitioners have found the platform getting in the way of the work. The Myers-Briggs Company moved all pricing to the Elevate subscription system, removing public pricing transparency and requiring an annual subscription of approximately $195 just to access practitioner resources, before any assessment credits are purchased. Reports and workbooks are additional costs on top of that. For practitioners running smaller practices or working with budget-conscious clients, those costs accumulate before a single participant has seen their results.

The forced-choice format also creates friction in delivery. When participants are required to choose between two options and neither fits clearly, the result is measurement noise rather than an accurate preference indication. That produces type results that participants do not recognize, which requires additional facilitation work to resolve and undermines confidence in the assessment. The best-fit conversation that follows is necessary because the instrument did not do its job cleanly the first time.

Type Discovery measures the same 16 Jungian psychological types using a non-forced-choice format that allows neutral responses when no clear preference can be identified. Differential Intensity Weighting captures both the direction and strength of each preference. The Type Precision Module adds targeted follow-up items only where clarity is needed, resolving ambiguity before results are delivered rather than after. The result is a type that participants are more likely to recognize as their own from the start.

Credits never expire. There are no subscription fees and no setup costs. The practitioner platform is included with a free Pro Account. And the cost per administration is lower than the MBTI.

Your existing MBTI training and knowledge transfers directly. Type Discovery measures the same 16 types using the same four dichotomies. The frameworks, resources, and interpretations you have developed over your career remain fully applicable.

Switching from 16Personalities or Truity

16Personalities and Truity have introduced psychological type to millions of people, and that reach has genuine value. Many practitioners find that clients arrive with some familiarity with the four-letter code, which shortens the introduction and creates an existing point of connection.

The challenge is that familiarity is not the same as accuracy. Both platforms use algorithms that assign type codes without the psychometric rigor of a validated instrument. Results are treated as definitive rather than as a starting point for a best-fit conversation. There is no Type Precision Module to resolve unclear preferences, no Differential Intensity Weighting to capture preference strength, and no practitioner platform to manage delivery, reinforcement, or documentation.

Participants who have taken 16Personalities or Truity have often internalized a type result that may or may not be accurate, and they have done so without a practitioner present to guide the process. When they bring that result into a coaching or team development context, the practitioner has to work with a consumer-grade result rather than a professionally administered one.

Type Discovery gives practitioners a professional instrument designed for practitioner-led delivery. The best-fit process treats results as a starting point for conversation, not a verdict assigned by an algorithm. The participant experience is built for development, not for conversion to paid reports. And the practitioner has full control over when results are released and how the session is structured.

Switching from the Majors PTI (Now Type Discovery)

If you used the Majors PTI through ACER’s online platform in Australia and are looking for a new home, Type Discovery is the same instrument. Mark Majors developed both the Majors PTI and Type Discovery, and the same non-forced-choice format, Differential Intensity Weighting, and Type Precision Module that made the Majors PTI accurate are the foundation of Type Discovery. Your existing knowledge of the instrument transfers completely. You are not starting over.

What Switching to Core Factors Actually Means

Getting Type Discovery to participants is project-based. You create a project, add participants, and send a consignment link or individual invitations. You control when results are released. Batch processing handles large groups. There are no subscription fees, no setup costs, and credits never expire.

After delivery, participants do not receive only a PDF. They access results through the Participant Hub, where full descriptions of all 16 types at approximately 2,400 words each are available for exploration. The Compare and Connect tool lets participants compare their type to colleagues and work through guided questions for bridging differences. My Journal supports structured reflection between sessions. Evidentra®, where you enable it, provides personalized AI coaching between your touchpoints.

The participant experience continues after the session ends, which means your work has a longer shelf life than a single debrief. Participants return to the material when a relevant situation arises rather than relying on memory of what was covered in the workshop.

Participant feedback and NPS reporting are built into every project at no additional charge.

You stop being the practitioner who delivers a type result and hopes it sticks. You become the one who opens a process your clients carry forward on their own.

What Practitioners Who Have Made the Switch Are Saying

“As someone whose work is rooted in the Myers-Briggs Type Indicator® and Jung’s theory of Psychological Type, I’m very protective of how Type is used. I care about ethics, depth, and helping people grow without reducing them to a four-letter code. That’s why I’m excited about Core Factors Type assessments and the Evidentra platform. It’s updated and modern, with an online experience that genuinely engages participants. It doesn’t force an either-or mindset, and it doesn’t push people into rigid categories. Instead, it supports learning and development. The way the platform shows results across both poles of a dichotomy is especially powerful, because participants can immediately see they have access to the full spectrum. The practitioner hub is comprehensive and well thought out, and the AI component is not a gimmick. I explored Evidentra using my participant account and asked a range of real client questions. The answers were strong and surprisingly useful. The more I used it, the more I thought, ‘My clients need this.’ I recently demoed the platform to a colleague who is also an MBTI Master Practitioner. She’s switching. That says a lot.”
– Cindy Paris, MBTI® Master Practitioner, Facilitator, Certified Professional Coach

“I have used, obviously, the MBTI system – a disaster the past couple years; Matrix Insights also with too many bugs for too long, and then Type Coach, which worked really well but I wanted more. What I love about your site is that it brings together Roger’s work including EQ, and all the other aspects of Type. It’s uncluttered, chunkable (so important in learning) and visually appealing! I’m excited to use it.”
