"The GAR2022 blames these disasters on a broken perception of risk based on “optimism, underestimation and invincibility,” which leads to policy, finance and development decisions that exacerbate existing vulnerabilities and put people in danger."

Optimism? I'd say it's apathy. Doomsday reports, also very correct and alarming ones, have lost their effect. People have become numb, pessimistic and just assume or even accept that everything is going to shit. They feel powerless to do anything about it, or are too occupied with their own economic relevance.
