That’s the unconventional conclusion from a thoughtful piece by Danny Finkelstein:

When I worked for the last Conservative Prime Minister and then for the party leader in opposition, we were obsessed with the idea of media bias. I spent hours on memos, assembling evidence.

I vaguely realised even then that it was a waste of time. Now I think it was actively counter-productive.

Why? Read the full piece to see (though I think actually his piece is more about how to avoid complaints that are counter-productive rather than saying that trying to tackle media bias is itself misguided).
