What’s the Amount of Google Bias in Search? DuckDuckGo Finds Out

Last week DuckDuckGo published a study examining the amount of Google bias in products like Google Search. CEO Gabriel Weinberg then told Business Insider:
What [our study] does reveal, or at least suggests, is that Google’s collection and use of personal data, including location, which is then used to filter specific search results, is having an effect akin to the effects of a political bias. That is an important nuance often missed in these discussions.
First, there’s a big difference between what a study suggests, and what it reveals. Language is important. Second, like other studies, the first one is interesting, but more studies need to be done in the form of peer review. I’d be interested to see one from an independent party that doesn’t have Google as a competitor.
