Does you know of a good resource to learn this kind of research/fact checking. I don't have an academic background but recently got interested in improving my ability to identify "fake news" and assess the validity of some paper. Where does one even start? Even finding the original paper seems a challenge, news articles mention one and then just to another news article. If I search the web for the title and author it feels like most websites are just rehosting the content, like with manuals/datasheets. Not sure how to get started here but your comment makes me think you might know some resources.
