The Washington Post, by default or design, has created a textbook example of what we call bias by placement, or displaying your news preferences by putting stories you like on Page A-1 and putting stories you’re not as eager to promote somewhere else. In the case of stories on our growing economy, which even the Post has come around to see as strong, a look at reporter Nell Henderson’s work reporting economic indicators shows a strong Post pattern of putting bad news on the front page and good news on D-1, the front page of the Business section.
