Psychology may not be "technical enough" because an adequate mathematical science or process theory is not developed for it, yet, but it's ultimately very important, perhaps critically important: see the last paragraph of https://www.lesswrong.com/posts/AKBkDNeFLZxaMqjQG/gaia-network-a-practical-incremental-pathway-to-open-agency. Davidad apparently thinks that it can be captured with an Infra-Bayesian model of a person/human.

Also on psychology: what is the boundary of personality, where just a "role" (spouse, worker, etc) turns into multiple-personality disorder?

Related, consciousness frame: where is the boundary of it? Is our brain conscious, or the whole nervous system, or the whole human, or the whole human + the entire microbiome populating them, or human + robotic prosthetic limbs, or human + web search + chat AI + personal note taking app, or the whole human group (collective consciousness), etc.

Some computational theories of consciousness attempt to give a specific, mathematically formalised answer to this question.
