That's what makes this experiment so interesting!
Because initially, the researchers had the same hypothesis. Yet their survey data collected from a highly educated, left-leaning audience gave the opposite result.
Major kudos to the NYU team here. First, for such an interesting outcome that's so contrary to their/our/everyone's assumptions. Second, for trying to help bridge the nasty partisan divide in American politics. It may be a futile task, but hey, somebody's got to try something...
