- Three systems through complexity science
- Can also be reframed as Non-linear causality
- Complex system can't be predicted
- One of the symptom of Complex problem assumed ordered is to make an attempt to predict a Complex system. Unfortunately, given that a complex system has a Non-linear causality, it's inherently unpredictable.
- Retrospective coherence should not be used for a complex domain
- Due to the Non-linear causality in a Complex system, it's dangerous to assume that we can use Retrospective coherence.
- Team size and communication lines has non-linear causality
- Adding a new team member will increase cost of communication. You might think that this will have a linear input (team size) and output (communication cost), but it actually has a Non-linear causality.
- Zoozve's orbit can't be predicted
- This is an interesting example of Non-linear causality, where just by adding one more planet, suddenly astrophysicist can't predict the orbit.
