I think you underestimate the various causes for willful ignorance. It is very easy for a tiny human to assume the planet is huge and little the human can do will be significant. Ask a human to imagine 100,000 people and they are already outside our capacity. To ask them to realistically imagine millions or billions over decades and, well, the behavior is undefined. I certainly think there are a LOT of people choosing to take the easiest (short-term) belief, but I also think there are plenty of people who just can't imagine people-scale impacting world-scale. I had a friend who made the argument that he thinks it is arrogance to assume humans can harm the global environment on the scale of climate change. I see it as arrogance to assume we CAN'T. But I don't think he's being disingenuous - he just handles the overflow error differently.
