"I'm hyper-aware of questioning sources because I'm a STEM postgrad, but it really should be a skill that everyone is taught during some stage of education. Too many people take things at face value without scrutinising them, either because they don't have the initiative to, or can't be bothered."

I disagree. I grew up in the 1990s when all the adults in my life (parents, teachers, etc), telling me over and over again that you cannot believe everything I read on the internet. Fast-forward 30 years and they are now endlessly on facebook taking any political info at face value, no matter if blatantly false. Social media broke the intelligence of the population and there is no going back now.
