Update: Here is the latest version of the Nudge Database pdf.
This is a list of empirical ‘nudges’ and their sources with a particular emphasis on those sourced from academic papers. It will be updated regularly. I created it because while there are many interesting papers and websites documenting nudges, there is a lamentable absence of any searchable, central database. If you know of some nudges that I have not included, please let me know by email or Twitter. The nudges listed here are intended as a quick reference: if you are looking for sample sizes and p-values you need to check the original paper. Where possible I have provided links to freely accessible versions of the papers.
