In 2012, Max Bazerman and four coauthors published a paper claiming that signing a promise to tell the truth before filling out a form produced greater honesty than signing it afterward.
Notes on verification
Confirmed by the original 2012 PNAS paper, retraction notice, 2020 replication study, and independent investigative and journalistic sources. Note the original finding was later retracted due to fraud in one study, though the claim only concerns what was originally published/claimed.
