I agree that it might not be as bad outside the US, as in the US they have more data to analyze and I'm in the EU, being more interested in news related to the EU.

But if we exclude location as a factor, it's not much of an argument because I have the benefit of constantly using both Google and DuckDuckGo, where DDG is now the primary search engine and Google is the fallback.

If Google personalizes the results in a way as to bias the information based on my political views or whatever, that's not something I have noticed. And believe me, I'd like more ammo when I criticize Google, but this ain't it in my experience.

True, but I've often switched back and forth between Personal Results and Global Results and rarely see a difference.

Nice Kafka trap!
