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. Guest results stay on your device. If you sign in, only the scores and result you save are stored with your account — we still never sell them.
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
Chunyang Liu
Independent maker
TraitTally is an independent project by Chunyang Liu, not a research lab, a clinic, or a staff of psychologists. Chunyang Liu is not a licensed clinician. The questionnaires and the guides are written in-house from the published structure of each framework, and when a reader points out an error at contact@traittally.com, it gets read and the page gets fixed. The tests stay free through the full result because the usual deal in this category is a short quiz and then a paywall in front of your own answers. Scoring runs in the browser, so there is no account to upsell and no result held back.
Not clinical advice, and not a hiring tool
Nothing on TraitTally diagnoses a mental health condition, a personality disorder, or any other clinical status. A type code is a description of answers on a short questionnaire. Do not use these results to screen job candidates, to make a medical decision, or to label someone else. If you are in distress, talk to a qualified professional.
