The first thing I tell all my undergraduate students in in my influence class, is that we're constantly influencing each other, whether we like it or not. With every word that you say, there are unintended consequences that you could not have anticipated on somebody else. Every time somebody comes to class, they hear things and they're influenced one way or another, either because I intend to by showing them evidence or talking about studies or psychology, or by accident, and every time they tell a story to somebody else, they're either intentionally or unintentionally influencing people all the time. So I think the influence process is part of being human. But what we want to do is, is do that in an ethical way and I think that's the key issue. People think stuff all the time and people don't know what other people are thinking, if I reveal to you what other people are thinking, and that influences your behavior, or you change your behavior, that has nothing to do with the information that I gave you! I just told you objectively what other people are doing. And I think that's an interesting distinction to draw. Now, the kind of explicit behavior change stuff like Do we want people to change? I think it's a moral question of what what as a society we decide is normative. We don't want people to steal stuff. And we do change people's behavior when they steal stuff. And we all think that's okay. If we decide we want to do the same for climate change, and maybe that's an ethical thing to do.
