Descriptive optimism is contingent: it’s an assessment about the world (or a part of it), and so it’s only warranted when it’s true. There are many aspects of the world that I am descriptively pessimistic about.
But prescriptive optimism is an attitude, a choice. It says that we’re going to work hard to solve problems and make the world and our lives better, no matter what, whether the prospects seem rosy or bleak. And I think we need more prescriptive optimism.
We need understanding, yes. As to whether we need optimism, that depends what kind of optimism you’re talking about. I’ve distinguished between descriptive and prescriptive optimism: https://rootsofprogress.org/descriptive-vs-prescriptive-optimism
