1/ The BEST thing about GOOD mental models and frameworks is their generalizability.
Are they USEFUL to advance understanding issues and find solutions?
2/ Readinf @slatestarcodex excellent piece on whether psychiatric conditions are clearly distinct CATEGORIES (in the way rabbits are rabbits + humans are humans) or DIMENSIONS (where people fall on spectrum with no clear demarcation line)...
3/ Found it useful in thinking about how we think about RACE, clear categories or spectra: light white to dark black, eye colors, hair textures, origin stories, group identity, family lineage, geography, rights, status, income, victim, pepetrator, justice, injustice...
