Scientific Foundations
The psychological theories, validated frameworks, and research traditions that inform the assessments on Intelligences Test.
Scientific foundations
The research traditions behind the platform
Intelligences Test is built on established psychological research, but we avoid pretending that every model is equally proven. A serious assessment platform has to distinguish between validated measurement traditions, clinical screeners, educational tools, and popular frameworks that are best used for reflection.
This page is a map of the science that informs the platform. It is not a complete bibliography. For citations organized by domain, continue to Our Sources.
Intelligence and cognitive ability
Cognitive tests are informed by modern intelligence theory and research on attention, memory, speed, and reasoning.
- Cattell-Horn-Carroll theory: a major framework for fluid intelligence, crystallized intelligence, and broad cognitive abilities.
- Multiple intelligences: used as a reflective framework for diverse strengths, with careful distinction from IQ measurement.
- Executive function research: attention, working memory, cognitive flexibility, inhibition, and processing speed.
Personality
Personality content is grounded in trait psychology while clearly labeling type-based tools as more exploratory.
- Big Five / Five-Factor Model: the most consistently validated academic personality framework.
- HEXACO: a six-factor model that adds Honesty-Humility and expands trait interpretation.
- Type frameworks: useful for self-reflection when presented as exploratory rather than definitive.
Emotional intelligence
Emotional skills are framed through emotion perception, self-awareness, self-management, empathy, and relationship management.
- Ability models: emotion perception, understanding, use, and regulation.
- Applied EQ models: workplace and leadership language for self-awareness and social awareness.
- Responsible interpretation: results describe skills and tendencies, not moral worth.
Mental health and neurodiversity
Mental health and neurodiversity pages are written as educational screeners and explainers, not diagnostic tools.
- Validated screeners: PHQ and GAD-style tools are referenced for educational context.
- Autism and ADHD research: dimensional models, trait patterns, and functional context.
- Clear limits: clinical diagnosis requires qualified professional assessment.
Relationships and attachment
Relationship assessments draw from attachment theory, communication research, and self-reflection models.
- Attachment theory: secure, anxious, avoidant, and related adult relationship patterns.
- Communication frameworks: practical models for discussing needs, conflict, and connection.
- Context matters: results should support conversation, not label another person.
Motivation, resilience, and growth
Growth-focused tests reference research on perseverance, mindset, motivation, and self-regulation.
- Grit and perseverance: consistency of interest and effort over time.
- Growth mindset: beliefs about learning, ability, and improvement.
- Self-determination theory: autonomy, competence, and relatedness as motivation foundations.
Evidence status
Popular frameworks are not all equal
Some frameworks on the site, such as Big Five personality or CHC-informed cognitive ability, have strong academic support. Others, such as MBTI-style types or love languages, are popular and useful for reflection but have more mixed empirical support.
When we use a popular framework, we do not present it as a clinical or definitive measurement. We frame it as a structured way to think, discuss, and reflect.
FAQ
Scientific foundation questions
Do you use DSM or ICD criteria for mental health pages?
We may reference DSM-5 or ICD-11 concepts for context, but our tools are educational screeners and explainers. They do not assign diagnoses.
Is the Big Five the same as Myers-Briggs?
No. The Big Five is a trait model with stronger academic validation. Myers-Briggs-style typing is more exploratory and should be interpreted with caution.
Where can I find full citations?
The Our Sources page organizes citations and reference traditions by assessment domain.
Why include popular models with mixed evidence?
Some popular frameworks are useful as conversation and reflection tools. We include them only when they are clearly framed and not overstated.
Science should clarify, not overpromise
