The clearest, the most powerful phenomenon that can be observed about human societies is this: Humans have two sets of instincts, the set that turns on during times of self-perceived fortune and plenty, and the set that turns on during times of despair.
The instincts of misfortune and desperation are characterized flagrantly by a conscious embrace of violence, by sexual conservatism, by nationalism and rallying behind leadership, by scapegoating, and other things. Human nature during times of plenty are characterized by sexual liberalism, idealism/altruism/moralism, democracy, and other things.
The most dramatic example of the “misfortune” instinct taking hold was Germany after world war I. Germany was among the mightiest and richest countries, and within a few short decades was impoverished. A people that go through such a fall naturally had their minds click a certain way. More modern examples abound. Middle easterners, who are taught the might of the old caliphates, are also struck by their present condition. Even the divide between red states and blue can be traced back to their stagnant non-urban economies. Their support for the President, for conservative social values, and for war, abound.
The most dramatic examples of the “fortune” instincts were the carefree children of the winners of WWII. The hippies. But the benefactors of the recent urban prosperity also wear the same stripes, worrying so much about the environment and gay rights. It’s no surprise that the richest countries from the ancient world, such as the Greek city-states, were also big on gay sex, democracy, and spoke much of doing the right thing.
Some of the interactions in these instincts is surprising. Rich old businessmen might be supposed to be under the spell of the instincts of fortune. Yet obviously they’re not. The reason is that business is a bitch. You spend your time dreaming about the money you might make, and remorsing about the money you didn’t. To say nothing of economic cycles. It’s much more stressful than a steady paycheck. Another non-obvious interaction is the fate of blacks following the civil-rights movement. It might seem natural that they would turn hippie-like, yet violence among them soared. This is because the fortune of real gains was offset by the constant talk of how poorly-off their lot was. The misfortune instinct couldn’t help but kick in. Also, the difference between Iraq and Afghanistan after their respective wars can also be explained. Afghanistan had reasonable peace and a wholesale enthusiasm for democracy because their country went from decade-long unending war to mere ordinary poverty. Feelings of fortune were high. Iraq, meanwhile, was quite prosperous during the 80s, it was conservative and somewhat liberal. A decade of devastating economic sanctions (thanks, Clinton) however turned that whole boat around. Going from high to low triggered a feeling of misfortune. A complete fuck-up of the reconstruction (thanks, Bush) cemented the point and caused chaos.
The presence of the transcendent, baffling, timeless dichotomy between “conservatives” and “liberals” can be traced to a fundamental, essentially instinctual, mechanism. That is why there is a very recognizable linear continuum, instead of a mishmash of permutations of beliefs. (Seriously, how many pro-sex, pro-war demographic groups have you seen?)
Many of the changes are rather obvious, from an evolutionary perspective. When times get tough, go to war. But it’s not all self-evident. The tie-in with sexuality is surprising (though one can speculate), and the way the emphasis on virtue/morality/democracy changes also gives pause.
Anyway, this is the first thing that sociologists should have understood and recognized. Have they yet? Actually, I don’t know. It doesn’t seem so. People keep talking about these issues of liberals vs conservatives since time immemorial, and I’ve never seen anyone explain it in a great context. For all I know, sociology has missed on grabbing the absolutely lowest-hanging fruit. The fruit that would have given some basic fucking answers. Even Galbraith, who wrote a book how economic growth leads to good things, didn’t grok the whole picture. It’s not exactly about money.
