GWD-5-Q20:
Scientists typically do their most creative work before the age of forty.
It is commonly thought that this happens because aging by itself brings about a loss of creative capacity. (an explanation that the argument challenges)
However, studies show that a disproportionately large number of the scientists who produce highly creative work beyond the age of forty entered their field at an older age than is usual. (a finding on which that challenge is based)
Since by the age of forty the large majority of scientists have been working in their field for at least fifteen years, the studies’ finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not that they have simply aged but rather that they generally have spent too long in a given field.
GWDQ25:
Scientists typically do their most creative work before the age of forty.
It is commonly thought that this happens because aging by itself brings about a loss of creative capacity. (an explanation that the argument challenges)
However, a study has found that almost all scientists who produce highly creative work beyond the age of forty entered their fields late and less than a dozen years before their creative breakthroughs.
Since creative breakthroughs by scientists under forty also generally occur within a dozen years of the scientist’s entry into the field, the study’s finding strongly suggests that the real reason why scientists over forty rarely produce highly creative work is not due to age but rather because most have spent too long in their fields.
(evidence in support of a competing explanation that the argument defends.)
