AI-based recommendations can improve individuals’ decision-making, but little is known whether they impact some individuals more than others. This study investigates whether AI recommendations influence choice disparities between individuals who are well and poorly equipped to make decisions. In an online experiment, 1001 individuals made financial choices while they were shown: good, bad, or no AI recommendations. We found that good recommendations reduced choice disparities between individuals with low and high financial ignorance, whereas the bad ones did not exacerbate them. The implications of this study can help foster an environment where AI aids contribute to overall consumer well-being.
