As a cognitive bias: That sounds like the "normalcy" (or normality) bias, "the refusal to plan for, or react to, a disaster which has never happened before" [0]

As a cognitive bias: That sounds like the "normalcy" (or normality) bias, "the refusal to plan for, or react to, a disaster which has never happened before" [0], [1]. As a logical fallacy: Based on skimming the list at [2], the "appeal to tradition" [3, 4, 5] fallacy seems close: "claim in which a thesis is deemed correct on the basis of correlation with past or present tradition". (Aka: appeal to tradition, argumentum ad traditionem, argumentum ad antiquitatem, back in those good times, conservative bias, good old days); or, maybe: argument from inertia, stay the course.
