Episode notes
Structure And Expertise Are Complementary
- Structural complexity and semantic expertise are complementary, not competing.
- Domain expertise boosts semantic richness while hierarchical complexity measures abstraction and integration.
Lectical Scoring Automates Complexity
- The Lectical Scale (Dawson) automates hierarchical complexity scoring from language.
- Lectica enables large-scale, comparable measurement of developmental complexity in texts and interviews.
Ego Development Tracks Complexity Levels
- Keegan's subject-object model maps ego development into five orders of consciousness.
- Dempsey quantitatively links Keegan's stages to hierarchical complexity via lectical scoring.
