Among the nearly 5,000 adults who participated in an online survey every two weeks from March to June, around 29% said they trusted CNN more than Fox; about half (52%) expressed no preference, and one in five (20%) said they trusted Fox more than CNN.

Devotees of Fox News consistently practiced more risky behaviors — such as going out to a bar or club, attending gatherings of more than 10 people or visiting others in their homes — than CNN viewers, the study found.

In addition, the study found Fox News enthusiasts consistently practiced fewer preventative measures — such as wearing a mask, sanitizing hands, avoiding restaurants and canceling social plans — than CNN fans.
