Accept that there is no source of info you can just believe at face value. You need to collect information from across your infosphere and intensively de-bias and cross-check it. It'll take a lot of effort. If that's not worth it to you, go agnostic on things you don't have time to figure out, or join a tribe and shout the slogans with your tribe-friends. Your life choices will depend on your values.
