We often think of possible responses to fear as fight, flight, or freeze. It is easy to transfer this thinking on our teaching about topics like sustainability and climate change: in response to realising the extent of the problems we are facing, students can step up and take action, they can just not engage with the material and ignore the threat as much as possible (if I don't think about it, it can't be real, can it?), or they can get paralysed by the enormity of the problem. According to this study, though, this is very unlikely to happen if you do "feat appeals" right.
