Four Claim Types
Each type of claim should be judged by a different standard.
- Framework definition: what the Myers-Briggs system says a preference or type code means.
- Research evidence: what independent psychology sources say about validity, reliability, and appropriate use.
- Editorial synthesis: patterns distilled from books, public discussions, and practical observation.
- Site heuristic: a deliberately simple tool or rule meant to be tested, not treated as scientific fact.
Primary Reference Set
These sources anchor the site's definitions and limitations.
Official definitions of the four preference pairs and the 16 type combinations.
Official guidance that type is one part of a person and results reflect self-report responses.
An independent psychology reference describing the instrument and its limited standing among research psychologists.
A discussion of validity, fairness, job relevance, and responsible test use.
Review Standard
Pages should answer one clear question, distinguish description from prescription, state meaningful limits, link to related pages, and record the date of material review. Corrections should be made in the source content rather than hidden in presentation code.
Independence and Trademarks
INTJ.org is an independent editorial resource. It is not affiliated with, endorsed by, or sponsored by The Myers-Briggs Company or Myers & Briggs Foundation, Inc. Myers-Briggs Type Indicator, Myers-Briggs, and MBTI are trademarks or registered trademarks of Myers & Briggs Foundation, Inc. in the United States and other countries.
INTJ.org is also not affiliated with, endorsed by, or sponsored by NERIS Analytics Limited, the publisher of the 16Personalities test. The Assertive and Turbulent identity dimension, the -A and -T suffixes, and the “Architect” label are that publisher's terminology. Where this site discusses them, as on the INTJ-A vs INTJ-T guide, it does so to explain third-party terms that readers encounter; it does not adopt them as part of its own framework, and it does not reproduce that publisher's descriptions.
Likewise, “Mastermind” is a role name from David Keirsey's temperament model, and the cognitive-function stack is a practitioner model descended from Jung's typology rather than part of the official four-preference framework. This site labels both as such wherever they appear.
