About TraitTally
Free personality tests that are honest about what they can and cannot tell you
What this site is
TraitTally is a free site for taking four of the most widely used personality tests: a 16-type test in the MBTI tradition, the Big Five, the Enneagram, and DISC. Every test here is free from the first question to the full result. That matters because the standard business model in this space is a free quiz followed by a paywall in front of your own answers, and we think that model has earned the distrust it gets. Each test also comes with a guide covering where the framework came from, what published research says about it, and how far to trust your result. The guides are blunt where the evidence is weak: the Big Five page explains why researchers prefer it, and the Enneagram page tells you its peer-reviewed support is thin before you spend twelve minutes on it.
How we work
Claims you can check
Where a page leans on research, it names the source: Pittenger on MBTI retest reliability, Barrick and Mount on conscientiousness at work. No anonymous "studies show".
Plain language
A guide should read like a knowledgeable friend explaining something, not a textbook or an ad. Jargon gets defined in the sentence that uses it.
Private by design
Tests are scored inside your browser and results are saved on your device only. We never receive your answers, so there is nothing for us to leak, sell, or subpoena.
Honest limits
Every test page states what the framework cannot do. A free 20-question DISC can rank your work styles; it cannot screen job candidates, and our page says so.
The four tests
Each test has a different job. In the order most people should probably take them:
- Big Five - 50 questions, five continuous scores. The model personality researchers actually use; start here if you want the picture with the most evidence behind it.
- 16 Types (MBTI) - 70 questions, a four-letter type. The shared-vocabulary test: best for putting words on how you differ from the people you live and work with.
- Enneagram - 36 questions, nine types. Sorts by core fear and motivation rather than behavior; the most reflective and least validated of the four.
- DISC - 20 questions, four styles. The workplace test: quick to take, easy to spot in any meeting.
Who makes this
TraitTally is a small independent project, not a research lab or a clinic, and we are not licensed psychologists. What we do is homework: the questionnaires and guides are written in-house against the primary literature for each framework, and when a reader points out an error at contact@traittally.com, someone reads it and fixes the page. Nothing on this site is clinical advice or a hiring tool. If you want to see exactly how each test is constructed and scored, including the parts where a free test falls short of a professionally normed one, the methodology page lays it out.
