There’s the cowardice answer. After years of being told they were liberal biased they’ve internalized this to an extreme. They’ll bend over backward to avoid being called biased no matter what. With one side making this claim no matter what, there is no end. Until they actually are completely biased to the side complaining they will never meet the standard, even then.
No matter that they can see the rain falling, they must report the weather is inconclusive least the side that will call them biased calls them biased.
There’s the cynical answer. To drive clicks. Anything that drives clicks is good. Crazy bad governance and chaos drives clicks. Bad news drives clicks. Boring stable governance doesn’t drive any clicks. Nobody watches the news to hear that things are just fine and boring, working as they are supposed to. While world in turmoil, disaster looming, chaos everywhere, are exactly what people turn to the media to hear what is going on.
No matter that they can see the rain falling, they must report that maybe it’s hail or a tornado, perhaps there are really pigs falling from the sky. Tune in to find out what crazy thing is happening. Never mind that it is just a normal drizzle.
There’s the extra cynical answer. Either the media owner or the direct person makes enough money to be in the 0.1% and just doesn’t want to pay more taxes. No matter any other impact. So they steer everything in that direction.
No matter that they can see they’re peeing on your leg, they’ll keep reporting that it is just raining.
