Do you know of any text media (e.g. newspapers, but also blogs that aspire to journalism) that "show their work"? More precisely, ones that describe not only what they figured out, but also how they did that and, ideally, also the failed avenues. An example of a publication that goes in that direction (but not as far as I'd ideally want to see someone go) is Bellingcat.
Maybe you know journalists who publish (with a delay and redactions, for obvious reasons) log of all the research they're doing?
