Remember, answering a poll is a way of asserting identity. Beliefs tend to be reverse engineered, as it were: People tend to construct an identity around what they (and their tribe) do. That suggests that they will only construct a different identity when they start doing different things.
So imagine the same guy who rejected human-caused climate change in the poll. Imagine that bike riding were made convenient and useful enough that he started doing it. Imagine that his neighbors started getting solar panels, to the point that he felt pressured to do it, and he became a power producer. Imagine he’s in the military and his platoon started insulating their tents and carrying solar water purifiers.
Fascinating short article on what polls really measure and how people’s actions with regard to the environment can change.
