It’s not an opinion, and that’s not what they were testing, they were testing to see if people, initially unaware of how endangered chimps really are, became more aware and more willing to donate to their protection depending on the media they watched. The survey they used purposefully disguised the reason why they watched the videos. People who watched Hollywood chimps consistently thought they were less endangered and were suitable as pets than they actually are, especially when compared to the people who watched the conservation video.
