I’m really not sure, if you look at things before the 20th century it’s difficult to see a pendulum swing pattern. That works relatively well between the 20th and 21st centuries, but I don’t think we can see it as a general rule. It’s also pretty dependent on the region you look at, and movements you decide to take in consideration or filter out. There is just so much room for biases, it’s easy finding a pattern because that’s what our brains are good at doing, but it doesn’t mean it is predictive of anything

That being said, this video from Three Arrows (aka Dan Arrows) “America coming Weimar moment” has interesting things to say on that specific comparison: https://youtu.be/CFDDf48nj9g

> Just reminds me of how much societies resemble a pendulum; swinging from one extreme to the other. And of course you have the problem that some people want to freeze it mid-swing, or worse tear the damn thing down completely.

Or keep pushing it to further and further extremes with each swing until it inevitably breaks under the strain. :(

I discovered the pendulum of social movements after reading Bertrand Russell's "The Ancestry of Fascism" at a relative young age (~16 years old), it only really made sense after my 30s though.

It required me watching, experiencing how things I had considered settled and humanity was over them started to turn back: the rise of fascistic tendencies in different societies, anti-intellectualism, etc. things that as a teenager/young adult I never considered could become societal issues again.
