how to change the behavior of a complex system

Global methods (like adding a global term to your hamiltonian)
- Try and enact global constraints
  - E.g. quotas
- Designing systems:
  - E.g. highways, court and governing system
Influencing individuals (like applying an external field)
- E.g. cambridge analytica type thing, where you try and design what people see, and therefore what they believe and how they act
  - This can be seen as sort of a personalize broadcasting system
- Via influencers
  - This can be seen as targeting influential nodes in a network.
  - This is the less underhanded version
    - Whereas targeted advertising delivers content to people based on some black box algorithm, influencers deliver content to people who choose to view that content
Changing the local interactions/behavior itself (like changing the strengths of the local terms in your hamiltonian)
- e.g. if there was a drug to make people “better suited for a large, interconnected society” would you take it?
