Modern macroeconomists ignored a long history of economic panics, in part, because they thought modern finance theory had learned these lessons and rendered history irrelevant. My own view is that the economic historians have a much better grip on the nature of panics and bring much more convincing evidence to the debate than macroeconomists relying on mathematical models with flawed assumptions do.
Footnote: Thomas Kuhn's, Structure of Scientific Revolutions (which is best known for the notion of a paradigm shift), with a similar methodology to economic historians (he wrote as a historian of science) is also in vogue.
In both cases, one of the key underlying premises is that history is one of the better suited disciplines to noticing and understanding "Black Swan's," i.e. dramatic and infrequent phenomena that change everything.
