Of course, because that made them so open to new ideas and 'nimble' right?
"The conservatism of the Spartans was often a strength but also a weakness. The state or society did not change and adapt to new social, political, and military realities. Sparta was unable to change- this meant that it was inflexible, and many even saw it as a petrifying society.
The Spartans did not change their military tactics and still used the traditional tactics even when other states in Greece, such as Thebes, were updating the phalanx formation. Then the Spartans could not change even when the citizen body went into a precipitous decline. There was no meaningful effort to reform the agoge system. The society seemed incapable of dealing with many of the problems that it faced in the wake of its victory in the Peloponnesian War."
