Psychology has a repeatability problem. Turns out Zimbardo wasn’t completely honest about how hands-off the researchers were. The Stanford Prison Experiment is the latest famous experiment in psychology that is proving difficult to reproduce.
I remember learning about this in school and the point being driven home: humans are selfish, and the only thing holding society together is a fragile veneer of civility, ready to burst free the moment no one is looking.
What does a selfish human species imply about society? It means that any vision of a community-oriented society, any revolution or reformation that purports to progress beyond a free capitalist market system in order to end capitalist exploitation, is naïve — nay, illogical.
Science has long been regarded as a pure discipline, abstracted from any particular society because of its faithful empiricism. Leftists ought to keep in mind that science, as with all knowledge, has a social character which cannot be separated from its time and place, and not therefore from politics. Science is a tool which may be wielded for technological progress within an egalitarian society, but by the same token may be used to lend authority to a ruling class who almost exclusively possess the means by which that science is carried out.
”[T]he human essence is no abstraction inherent in each single individual. In its reality it is the ensemble of the social relations.” —Karl Marx, Theses on Feuerbach
There was a study that claimed that if you aren't WEIRD (Western Educated Industrialized Rich Democratic) psychology is basically pseudoscience. It even goes further to say that if you're a mainline liberal psychology has better outcomes for you.
