I happen to know about biased reporting from personal experience. We had an accidental pesticide spraying of some farm workers in my area about 14 years ago. Plane sprayed the wrong field. The grower had a plan in place, had a doctor all ready picked out and a plan--they go home or whereever, wash, change clothes and go straight to the doc. Doc was out, but I was there, his colleague. We saw about 35 people very efficiently, nurses asking a list of questions, drawing blood test, and doc (me) going from room to room doing exams.
One of the things we checked was whether the women were pregnant, and test came back that one was, so she got special attention and followup from me, but she never had any symptoms or blood test abnormalities.
CBS reported the story about the poor farm worker who was sprayed with pesticide and was pregnant and hadn't even seen a doctor. I, an M.D., had seen her three times before this story came out. I was the one who had told her she was pregnant, which was news to her.
