The Immunological Imagination
Salk's analogical method for understanding cognitive development — the distinction between active and passive immunity applied to the question of what AI does to the minds that use it.
The immunological imagination is the analytical framework Salk's life in virology produced for thinking about any form of amplification. Its core distinction is between active immunity (earned through encounter and struggle, encoded in the organism's own architecture, durable) and passive immunity (borrowed from external sources, temporary, requiring continuous replenishment). Salk's polio vaccine produced active immunity by providing the immune system with molecular information — the dead virus — that triggered the organism's own learning processes without requiring actual infection. The vaccine worked with the immune system, not instead of it. Applied to cognitive development, the framework yields a diagnostic question about AI: does the tool produce active cognitive immunity (amplifying the user's own developing capacities) or passive cognitive immunity (providing borrowed competence that disappears when the tool is withdrawn)?

The distinction between active and passive immunity is precise biology. A newborn receives antibodies through the placenta and breast milk — passive immunity that provides immediate protection
