Somewhere in your feed right now, someone is citing “research” to support something that research does not actually support. The problem isn’t a shortage of information. It’s that most of us were never taught to navigate it at the level where it originates. Academic and scientific papers are where claims about the world are supposed to get tested. Where hypotheses meet methodology, where evidence gets weighed against competing explanations, where researchers have to show their work in a way that other researchers can scrutinize. The system is imperfect, sometimes deeply so, but it’s also the most rigorous process we have for building reliable knowledge.
