Connections
How the frameworks fit together
The four frameworks measure different things, but they are empirically connected: thinking style’s E/I correlates 0.70–0.74 with extraversion, and S/N correlates 0.70–0.72 with openness. SELVET uses those connections actively — one answer updates estimates in several frameworks at once.
Four lenses on the same person
The four frameworks in SELVET – Big Five, thinking style, motivation and values – are not isolated systems. Research shows systematic correlations between them.
Think of the frameworks as different lenses, each illuminating a different aspect of the same person:
- Big Five: Behavioral tendencies and dispositions
- Thinking style: How you process information
- Motivation: What you strive for and what you fear
- Values: What matters to you
The research shows clear patterns
Big Five ↔ Thinking style
McCrae and Costa (1989) found strong connections:
- E/I correlates with Extraversion (r = 0.70–0.74)
- S/N correlates with Openness (r = 0.70–0.72)
- T/F correlates with Agreeableness (r = 0.40–0.50)
- J/P correlates with Conscientiousness (r = 0.50–0.55)
Big Five ↔ Enneagram
Hook et al. (2021) found:
- Types 7 and 8 correlate positively with Extraversion
- Types 4 and 6 correlate positively with Neuroticism
- Type 1 correlates positively with Conscientiousness
- Types 2 and 9 correlate positively with Agreeableness
Big Five ↔ Schwartz values
Parks-Leduc et al. (2015) found:
- Openness correlates with Self-Direction and Stimulation
- Agreeableness correlates with Benevolence and Universalism
- Conscientiousness correlates with Conformity and Security
One answer updates several frameworks
When you answer a Big Five question, it updates not only the primary dimension, but also correlated dimensions in the other frameworks:
Example: "I have a vivid imagination" → 5 (Strongly agree)
→ Openness: +0.15
→ Thinking style N (Intuition): +0.11
→ Type 4/5/7 probability: +0.06
→ Self-Direction (value): +0.04
The strength of the update is weighted by the strength of the research – stronger correlations give larger updates.
Handling conflicts
Sometimes different parts of the test give contradictory signals. For example:
- Big Five: Very high Extraversion (90%)
- Enneagram: Tends toward Type 5 (typically introverted)
SELVET handles this by:
- Flagging the inconsistency
- Triggering follow-up questions for clarification
- Presenting a nuanced result that acknowledges the complexity
- Allowing that some people genuinely have atypical combinations
Advantages of the hybrid approach
Greater robustness
Using four frameworks reduces the influence of random answering errors, the Barnum effect, and social desirability within any one framework.
A richer picture of a person
One dimension (say, "introvert") gives limited insight. Four perspectives on the same person give a far more nuanced picture.
Better practical advice
With more data points, SELVET can give more precise recommendations for career, relationships and personal development.
SELVET measures your internal consistency
SELVET calculates a consistency indicator showing how well your answers agree across the frameworks:
- 90–100%: Very consistent – high confidence
- 75–89%: Good consistency – a reliable profile
- 60–74%: Moderate – some nuances worth exploring
- <60%: Low – consider whether context affected your answers
Four lenses give a richer picture
The frameworks in SELVET are designed to work together. The correlations are real, cross-mapping increases precision, unique information is preserved, conflicts are handled, and the result is a richer picture of personality than any single test can give on its own.
