I just looked up “presidential race 2024” on Google, DuckDuckGo, Bing, Yandex, Luxxle, and Tusk.
All the results looked about the same. The biases weren’t especially strong, but Google definitely returned more NYT and CNN stories than the others.
The problem is that they all censor anyone who doesn't adhere to the narratives. That's easy to hide in the algorithms, just make sure all highest weighting is directed towards establishment sources. Some of that is simply a circle jerk (they link to each other). But there are an infinite number of more devious ways to do that e.g. using opaque woke AI.
