For books and journal articles, there are a lot more checks and balances in the publication process. For example, an academic book deal is not given to just anyone-only an expert in the field.

Look at the words of the author to see if they are objective and impartial or emotionally charged.

Take a look at these examples of how language changes depending on a personal view of an issue. Do you see the bias?
