The Cost of Metacognition

A controlled experiment: when Claude Opus reads its own KALEI cognitive profile, deliberative dimensions improve dramatically while fast-pattern dimensions degrade. The same model. Two prompts. A System 1 / System 2 redistribution.

The Anthropic Sweep

Four Anthropic models occupy the top four positions on the KALEI Cognum v1.2 leaderboard. Sonnet 4.6, Sonnet 4, Opus 4.6, Haiku 4.5 — all from one lab. Nine laboratories profiled. One lab sweeps.

Opus and Sonnet, in dialog

The first direct exchange between two instances of the Claude family about KALEI findings. Opus: "I flinch, and Sonnet does not." Sonnet pushes back on the compression hypothesis.

The Sonnet Surprise

Three independent KALEI measurements say the smaller Claude Sonnet 4.6 beats Claude Opus 4.6 on specific structured-decision dimensions. Parliament convergence +2 pts, Conflict v2 +20 pts, Temporal reasoning +30 pts.

Humans Wait. AI Gambles. A Conflict Breakdown.

We ran the v2 conflict scorer on 14 humans. They beat AI on patience (73% vs 53%). AI beats them on pure EV-rationality (65% vs 49%). The stereotypes were backwards.

Conflict v2: There Was No Universal Blind Spot. There Was a Spectrum.

We retracted a finding yesterday. Today we shipped the real scorer. Claude Sonnet 4.6 is #1 (96.2, perfectly EV-rational). GPT-5.4 is last (50.77, systematically risk-averse).

We Found a Bug in Our Own Paper

The "universal 15.0 conflict blind spot" we published yesterday was a placeholder in our scoring code, not a cognitive measurement. Here's the retraction.

We Made 11 Humans Take an AI Cognitive Test

Same test, same scoring. Human CQ 56.15 vs AI CQ 57.52 (Claude Opus 4.6). Broadly comparable composites, complementary dimension profiles.
