Modeling psychological shifts as phase transitions / "cusp catastrophes" — the transitions between developmental stages (e.g., #Piaget, etc.) or collective learning/behavior akin to #cascades in ecological composition.

"If we exchange info all the time, then why are we not all the same? There are lots of different answers and they all work. One answer is sparse #networks [in which] it's quite easy to get #polarization."

"Due to interactions, people also increase their involvement...conservatives move to the activist position...a new way to explain #polarization due to this foldability or #hysteresis."
- Han van der Maas, on dynamics of entrenchment & extremism:

"We need a phase transition model of the individual...then we put it into a social network model, and we get a multi-level computational model of collective #learning."

Applying multi-level network models to #addiction, in which ecological phase transitions (e.g., outbreaks of organisms like the spruce budworm) look "cuspy" just like someone developing #alcoholism.
