Critics of evolutionary psychology object that it is not rigorous science c
ompared to other evolutionary science. Advocates reply that it is rigorous
science, and that the critics are uninformed. Still, informed people having
opposing preconceptions of what counts as rigor may reach opposing evaluat
ive conclusions. I shall clarify the very idea of rigorous evolutionary his
tories in relation to the basic objection that "evolution without history"
is not rigorous.
