Why the Most Valuable Things You Know Are Things You Cannot Say

- Expert judgement is learnable through calibration (experience) but not transmissible through instruction, because it relies on high-dimensional pattern-matching models.
- Language is a low-bandwidth, serial channel that cannot capture the complex, nonlinear interactions between many variables that experts unconsciously integrate.
- "Book smarts" involve low-dimensional knowledge transmissible via language, while "street smarts" involve high-dimensional experiential judgement that appears inarticulate.
- Institutions often prioritize legible, book-smart credentials over illegible experiential judgement, leading to failures in domains requiring nuanced expertise.
- Expert models are implemented in neural networks that learn through repeated feedback, without explicit symbolic representation, and require perceptual calibration to recognize relevant features.
- Knowledge exists on a hierarchy of transmissibility, from explicit facts to perceptual calibration, with the latter being learnable only through direct, prolonged experience.
- Organizations that codify expert judgement into rules and frameworks often discard the non-transmissible components, making systems fragile in non-routine cases.
- The most valuable expertise resists formalization, requiring personal calibration through feedback-rich repetition, which cannot be scaled or accelerated significantly.
