The researchers collected their first data in October 2023 and March 2024. Initially, they were struck by how inconsistently Google showed its warnings. A deep learning model they built to analyze the queries suggested that the warnings should have appeared between 29 and 58 times as often as they did in practice. For motivated conspiracy peddlers, they were easy to evade: just adding quotation marks or a single letter to a query was typically enough to make the banner disappear.

The researchers were beginning to collect additional data last September when they discovered something unexpected: Google had stopped showing low-quality banners entirely, weeks before early voting began, without disclosing it.

NEW: Google used to warn you when you were seeing low-quality search results. Then, in the weeks leading up to the 2024 election, the company quietly turned that warning off www.platformer.news/google-data-...
