Books and journal articles have more checks and balances in the publication process than web sites. For example, an academic book deal is not given to just anyone--only an expert in the field. But even this gatekeeping process does not eliminate all biased materials. Take a look at this example from testimony given before Congress to see how language changes depending on a personal view of an issue. Do you see the bias?

"False or biased information may be presented as a factual statement. But there may be signs that the facts may be flawed or misinterpreted. Read closely to see if the author is objective and impartial or emotionally charged."
