Temporal Processing Architecture and IQ Test Validity: Construct Misspecification in Neurodivergent Populations

This paper presents a construct validity analysis of Intelligence Quotient testing as used in university admissions and standardised selection mechanisms. Drawing on the Equilibrium Ledger framework, it argues that IQ tests primarily measure compatibility with chronological and procedural temporal architectures rather than general cognitive capacity. Synthesising psychometric literature on neurodivergent split profiles, timed versus untimed performance divergence, and real world achievement mismatch, the paper demonstrates systematic architectural bias against interpretive and relational cognitive processing. Implications for assessment validity, admissions reform, and cognitive diversity in higher education are discussed.
