Treatment arm 2 will watch a documentary and then read the paper before answering questions. The last two arms will only read the paper or only watch the documentary. We added a pure control group when the sample reached approximately 600 respondents, and continued to randomly assign participants thereafter to 5 different groups to include this pure control.
