"The difference between the above and most pseudoscientific cyclical theories is that politics, economics, and sociology are by their nature subjective, unlike physics. Observations derived from these disciplines are rooted in opinion, not in empirical reality; hence, it is possible to construct just about any cyclical theory one wants from them."
This reads like an extremely poor interpretation of the social sciences. Many ideas in the social sciences are rooted in empiricism, and it's quite ridiculous to just act like they're immediately invalid or pseudoscientific. --Otend (talk) 03:24, 5 December 2015 (UTC)
