On the usage of multidisciplinary mental models

• facts are not enough, you need models which is the structure facts hang off.
• you need many models, otherwise you'll see everything through the narrow lense of a single pattern
• models are effective ways to understand aspects of complex systems
  • therefore models should come from a variety of disciplines, to capture more aspects of the whole interconnected complexity
• a minority of models will carry the majority of weight. 80/20 rule.

learn the fundamental ideas in each major discipline, always prefer the explanation that uses more fundamental ideas –> use the checklist style for these fundamental ideas

use a big bag of multidisciplinary tricks, mastered to fluency, applied to all complex problems in life
