a, Pearson’s correlation. b, Pairwise order consistency. Histograms across 52 category–feature pairs for linear correlations (left) and pairwise order consistency (; right) between semantic projection ratings and human judgements ( participants per category–feature pair), before (black) and after (blue) adjustment for inter-rater reliability in ratings. Points show category–feature pairs, vertical lines show medians and semi-transparent rectangles show 95% confidence intervals. Curves show approximated data distributions, with density (in arbitrary units) on the y axis.
