The famous answer is a wasted answer
Ask a room to name a volcano and the first three replies will be the same. That is not ignorance, it is how memory works: the best-known members of a category are the ones that come back fastest, for everybody. So the useful skill is not recall but continuation. The first volcano costs you nothing to produce and earns almost nothing. The fourth one, dredged up after the obvious three have been discarded, is where the depth actually comes from.
