Illustrative plots of the linear relationships between each controversial theme and one of the cognitive traits: tolerance of ambiguity. Hexes show binned 2D density plots (with density scaled such that the peak density in each subpanel has a value of 1). Linear fits are shown in red (mean predictions with 99.9% CI ribbons). The correlation coefficient (Pearson’s r ) corresponding to each fit is annotated in the top left of each panel, along with a t -value (for a full table of numeric results, see Supplementary Table 4 ). The OSF repository ( https://osf.io/zyec9/ ) contains additional analyses, including non-parametric (Spearman’s r ) models of the above, illustrating how these associations do not depend on an assumption of linearity. The OSF repository also contains similar plots for the other controversial themes, along with density plots for the binary variables such as research areas and methods.
