Not all bubbles are harmful. I’m in a regional bubble when I search for “restaurant”. I’m in a programming language bubble when I search for coding issues.

Tune it to be less bubbly with controversial topics, perhaps.

"Everyone should get the same search results." is really just rightspeak for "Everyone should be in my bubble."

part of the issue with 'bubbles', as I see it, is that you don't know you're in a bubble. a big huge honking option of "keep me in the bubble" and "show results outside my bubble" would make it a lot more obvious (and manageable) to many people who are oblivious to the notion that they live in an information bubble. won't stop people who only use one source of news, but in a search aspect, it would be useful.
