Figures

Figure 1 The P index across the two phases. Time course of the P index (tracking the preference for decks with high payoff) for the four groups during the experiment. Left: values of P during the five blocks of the first phase, grouped by Condition in the first and in the second phase. Right: A comparison of P at the end of the first phase and during the second phase, where no feedback was allowed. Points represent mean values ± SEM.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
