Cultural Intelligence
Human knowledge compounds because a group evaluates it, normalizes it and passes it on. The mechanism is social, and it sits outside any individual head.
Culture starts as signals people notice and argue over. Taste points shared attention at what might matter. Trust compresses a history of validation so nobody has to check everything alone. Valence is the charge a signal carries: pull, fit, novelty, belonging, refusal. What a community keeps is whatever survives all three.
Consensus coordinates a group. It does not make the group right. Every act of normalization keeps some distinctions and erases others, and the shape of the network decides which ones: who observes whom, whose judgment travels, where dissent stays legible.
We treat cultural intelligence as cumulative social learning: a shared ability to judge experience, keep its context, and build on judgments already made. The hard part is making that legible without flattening it into a single number.
