The effects of base rate neglect on sequential belief updating and real-world beliefs

Fig 7

Prior noise relates to belief oddity outside the laboratory.

(a) Summary of group-level differences for noisy-sampling model-based and model-agnostic measures between the low (n = 57) and high (n = 34) PDI groups. Bar plots are effect size (Cliff’s delta, δ) and 95% confidence intervals. (b) Scatterplot showing a positive correlation between ranked mean PDI scores and (n = 116). Values are adjusted by parameter values and the model fit (RMSE) for specificity as in the partial Spearman correlation analysis. Boxplots show medians (blue lines) and 25th and 75th percentiles (bottom and top edges, respectively). The solid black line reflects the least-squares linear fit to the data points. Mean PDI is the average of the global PDI scores across the pre-screening and the experimental sessions for each participant.
