Researchers say Google AI Mode changes recommendations based on your emails — and it risks creating a giant confirmation-bias machine
Researchers have found that Google's AI Mode may be influencing search results based on users' Gmail activity. This personalization could lead to a confirmation-bias effect, where users are shown more familiar brands rather than discovering new options. The findings suggest that while AI can enhance search efficiency, it may also limit exploration and serendipity in online searches.
- ▪Brands linked to Gmail activity appeared more frequently in Google AI Mode results.
- ▪The effect was particularly strong for shopping searches, with certain brands showing up almost three times as often.
- ▪Researchers warn that this could create a confirmation-bias machine, reinforcing existing habits instead of promoting discovery.
