I agree on bias. Social media and algorithms amplify that. Adaptive tools (fbook, youtube, google search) feed you what you liked previously and amplify it further. I try to read moderate-left sources to avoid being biased by more natural right ones. It is usually transparent when they are biased [say, blaming bad decisions by Obama admin, but avoiding naming them. Just match the dates yourself]. If I feel I start believing what they are saying, then I take a detox.
And I think, Jewish learning should help everyone learn basics of questioning sources, literary analysis – what is missing, who is saying, what if there is a mis-attribution, etc
