Researcher publishes paper on interaction effects of digital nudges in optimal stopping games
Get up to speed
Batisse Manhardt and Ja-Nae Duane published a paper based on a 2^3 between-subjects factorial experiment (N=181) of the secretary problem, examining the individual and combined effects of three types of digital nudges—anchoring, salience, and social proof—on stopping behavior and outcome quality in sequential decision-making tasks. The study found that anchoring nudges significantly increased exploration (b=1.207, p=.017), while salience nudges had the smallest effect. The combination of anchoring and social proof nudges yielded the worst outcome quality ($181.83 vs. $192.21 for anchoring alone), and outcome quality decreased monotonically as the number of nudges increased.
