Is traditionalism bullshit?

[Anomalocaris]

The main argument for traditionalism, and it is not an argument that can be trivially dismissed, is in essence this: a working society is a supreme good. A traditional society clearly works, otherwise it wouldn't have lived long enough for its views to become customary and its institutions to become traditions. Since societies and human behaviors are highly complex and often difficult to thoroughly analyze and predict, breaking with what works could never be guaranteed to result in things that would work as well as before, nor could the unforeseen cost of the change be guaranteed to be less than the alleged benefit of the change.
