Correction to: Humanities and Social Sciences Communications https://doi.org/10.1057/s41599-023-01624-y, published online 10 April 2023.

In Figure 3 in the original publication, the semi-transparent ribbons representing the 95% confidence intervals on the linear models were not visible, due to a technical problem with the file uploaded by the authors. This has now been corrected.

In addition, the supplementary appendix file was uploaded in a .tex format. This has now been replaced with a PDF version to ensure all readers are able to access the file.
