What does SL-TDI measure?

Highly individualized results, thousands of different Type Portraits

By eliminating either/or forced-choice and instead treating each of the eight Type Modes (introverted and extraverted Sensing, introverted and extraverted Intuiting, introverted and extraverted Thinking, introverted and extraverted Feeling) as if they were independent of each other and measuring the usage of each with a 5-point Likert-like scale, the SL-TDI can easily generate thousands of distinct Type Profiles. Consequently, instead of putting all of humanity into either four or sixteen "boxes" (personality categories), the SL-TDI shatters the limits of those previous approaches and provides far more individualized results.
