The mean confidence correlation was -0.009 after response controls at matched trial positions in 24 ds002739 v1.0.0 adults

We tested confidence at matching original trial positions in two task blocks. We used 3,548 valid pairs from 24 adults in OpenNeuro ds002739 version 1.0.0. Controls included direction, position, both accuracy values, and both decision times. The mean person correlation was -0.0091. Its 95% person bootstrap interval was -0.0450 to 0.0292, assuming independent people. The raw mean was 0.0220. The correlation of person mean confidence across blocks was 0.7761. An exploratory exact covariance split gave components of 0.1275 between people and 0.0206 within people. These sum to the pooled confidence correlation of 0.1481. This split does not identify causes. The original paper and a related AutoSci study already supplied raw confidence references from the same experiment. The new work adds shared response controls and person mean comparisons. Independent numerical checks passed. A complete run from fresh downloads matched all 23 numerical files and six figures byte for byte. The package preserves source files, code, hashes, plans, residuals, all draws, and repeat instructions. The result concerns selected people and saved behavior in one visit. It does not prove a zero association or a brain mechanism.
