This reflects a real change in how people think. It is a sign of damage. Damage wrought on people's souls – especially among elites – by formal schooling and related pervasive dominance relations in employment. Continue reading

Fluid intelligence is pretty much anything you can use a spatial metaphor to think about, and is measured pretty directly by Raven's Progressive Matrices. It's used for puzzle-solving.

Crystallized intelligence, on the other hand, relies on your conceptual vocabulary. You can do analogical reasoning with it – so it lends itself to a fortiori style arguments.

I don't think it's just a coincidence that I know of two main ways people have discovered disjunctive, structural reasoning – once in geometry, and once in the courts. Continue reading
