TBH, I just don’t think something better is possible - I suspect that there are no valid shortcuts to trust.
That’s why I like MBFC. I understand it’s impossible for them to be perfect and unbiased. But no one else is doing that work, so I’ll take what I can get.
Even a trusted source can prove unreliable on a particular topic.
I like the rule of thumb that good sources are more likely to be biased when reporting things internal to their own country. I usually look for the BBC, but if it’s about the UK, I’ll find another source. Al Jazeera is similar.
