By adopting statistical techniques to previous five merger cases, they discuss that these media mergers, such as the merger of "The New York Times" and "The Boston Globe", did not show any statistical correlation with reduction of viewpoint diversity on the media. Responding to their point, Baker argues back that they mistakenly pay attention to the impacts of mergers on viewpoint diversity. Baker argues that source diversity should be focused instead.
