I find the idea that there can be an unbiased news source deeply problematic. All reporting of an event has to be from a perspective, and has to make decisions about what to report, what to leave out; what to emphasise, what to play down. An honest news source should be one that is one that is honest about its own biases.
There is the argument that if people were equipped with the skills to identify bias in reporting themselves then these news sources would not be able to operate as effectively and with as much influence as they do today.
For example, in Swedish schools children are actively taught to identify and evaluate biases in news sources as a way to filter false reporting [1].
It we start giving children the toolbox required to live in our (real) world of imperfect reporting then the impact of biased news sources might be neutralized in a generation.
