Our Methodology

How we build, score, and validate the personality assessments on Test My Persona.

The Frameworks We Use

Every assessment on this site is built on an established psychological or organizational framework. We do not create proprietary type systems or invent new categories. The frameworks include:

  • Myers-Briggs Type Indicator (MBTI): Based on Carl Jung's theory of psychological types and developed by Isabel Briggs Myers and Katharine Cook Briggs. Produces one of 16 types based on four cognitive preference dimensions.
  • Big Five (OCEAN): The gold standard in academic personality psychology. Measures Openness, Conscientiousness, Extraversion, Agreeableness, and Neuroticism on continuous scales. The most scientifically validated personality model available.
  • Enneagram: A motivation-based framework describing nine types organized around core fears and desires. Developed through a combination of spiritual and psychological traditions, widely used in coaching and therapy.
  • DISC: A behavioral assessment framework developed from William Marston's work. Describes four behavioral dimensions — Dominance, Influence, Steadiness, and Conscientiousness — with particular relevance in organizational contexts.
  • Love Languages: Based on Gary Chapman's five love languages framework: Words of Affirmation, Quality Time, Physical Touch, Acts of Service, and Receiving Gifts.
  • Attachment Style: Grounded in John Bowlby and Mary Ainsworth's attachment theory, extended for adult relationships. Describes four patterns: Secure, Anxious, Avoidant, and Disorganized.
  • Holland Code (RIASEC): Developed by John Holland, this framework classifies work interests and environments into six types: Realistic, Investigative, Artistic, Social, Enterprising, and Conventional.
  • CliftonStrengths: Developed by Don Clifton at Gallup. Identifies natural talent themes across 34 dimensions, organized into four domains: Executing, Influencing, Relationship Building, and Strategic Thinking.

How Our Questions Are Designed

Questions are drawn from or adapted from validated item banks associated with each framework. For each assessment, we follow these principles:

  • Questions use clear, everyday language without jargon or leading phrasing.
  • Most assessments use a 5-point Likert scale (Strongly Disagree to Strongly Agree) for granularity without cognitive overload.
  • Reversed-scored items are included to reduce acquiescence bias — the tendency to agree with statements regardless of content.
  • Question sets are balanced across the dimensions they measure, ensuring no single trait is systematically over- or under-represented.
  • Item counts are set to the minimum needed for reliable scoring — sufficient for meaningful results without unnecessary length.

Scoring Algorithms

Each assessment uses a scoring algorithm specific to its framework:

  • Trait scores are calculated by summing responses on relevant items, with reversed items inverted before summing.
  • Raw scores are normalized to a 0-100 scale for assessments that display percentage-based results (Big Five, DISC, Love Languages).
  • For type-based assessments (MBTI, Enneagram), scores on each dimension are compared to determine the dominant preference or type.
  • All scoring is performed entirely in the user's browser. No answers are transmitted to any server.
  • Scoring algorithms are unit-tested with edge cases including all-agree, all-disagree, and reversed-item patterns.

Privacy and Data Handling

We take a privacy-first approach to test data:

  • All test processing happens in your browser. Your answers are never sent to our servers.
  • We do not store individual responses, build user profiles, or share any data with third parties.
  • If you use the share feature, your answers are encoded as a URL parameter using lossless compression. The encoded string lives only in that URL — we do not store it.
  • No registration or email address is required for any assessment.
  • Analytics data (page views, test starts, test completions) is collected in aggregate via Google Analytics. This data does not include individual test answers.

Limitations and Appropriate Use

Personality assessments are tools for self-understanding, not diagnostic instruments. Important limitations to keep in mind:

  • No online personality test is a substitute for clinical assessment or psychological evaluation.
  • Self-report measures depend on honest, reflective responses. Results reflect how you see yourself, which may differ from how others see you.
  • Type-based frameworks (MBTI, Enneagram) force people into categories. Most traits are distributed on spectrums, and many people score near the middle of dimensions.
  • Personality preferences describe tendencies, not capabilities. No type is more or less intelligent, capable, or valuable than any other.
  • Results should not be used as the sole basis for hiring, admissions, clinical, or other high-stakes decisions.

Used appropriately, personality frameworks are among the most accessible and practically useful tools for self-understanding available. The goal of every assessment on this site is to provide accurate, honest, actionable insight that helps you understand how you think, communicate, and relate to others.
