A keyword stood out to me: “A type 1 error is often considered to be more serious, and therefore more important to avoid, than a type2 error.” Actually, I held the same view before when learned the concept of error types in AP Psychology. But now I realize type 2 error can lead to a serious outcome as well, not because the error it self, but its concept which will give people a delusion that anything could be false. “So while the pattern of weather events was clearly changing, many scientists insisted that these events could not yet be attributed with certainty to anthropogenic climate change.” And thus it caused human being missed the most important opportunity to save the earth.
My view on that governments “were at first unwilling and then unable” to intervene effectively: Yes, of course, because protecting the environment will more or less affect the economy, which means it will undermine the profit of some interest group. And most of the time, those interest groups support the government.
