Psychometric Social Sorting / 心理测量式社会分层

Psychometric social sorting / 心理测量式社会分层 is the episode’s core mechanism: using psychological tests or measured traits to allocate people into social categories with different rights, expectations, opportunities, or stigma. 37.智商测试：请问你是智力婆罗门吗？ follows that mechanism from [[FrancisGalton|Galton]]’s anthropometry to [[IntelligenceTesting|intelligence testing]] in schools, immigration stations, military selection, institutional diagnosis, and courts.

The problem is not only whether a test is accurate. The source asks who uses the number, what background differences the number hides, and what happens after the number is assigned. Once a score becomes destiny, [[GoodhartsLaw|Goodhart’s Law]] and [[CulturalBiasInTesting|cultural bias in testing]] both matter: people optimize for the measured signal, while institutions mistake the signal for the whole person.

Key Claims

• A test can become a social sorting device when its result controls access to education, migration, work, reproduction, or status.
• Context-blind measurement can make class, language, cultural familiarity, and fatigue look like innate deficit.
• Sorting becomes more dangerous when the label follows a person across institutions.
• The episode treats “智力婆罗门” as a contemporary cultural echo: a cognitive-score hierarchy can become an identity and contempt system even outside formal policy.
