I write every day. Most days I need to lookup information so that I am providing support for my writing. To assure the reader that I’m not just making stuff up, I like to provide references for my comments. I am, after all, an academic and, as such, it is incumbent on me to provide accurate, valid information. References provide evidence of validity.
Way back in the day doing a digital search required some fairly advanced skills in building a search query that would give you the results you needed. Today, thanks to advanced search engines like Google, even a sloppy, half defined search prompt will give you the results you’re looking for. The challenge, though, is determining whether the results are truly valid. That is, the search engine delivers links to websites and other resources that answer the question, but it is often not clear whether those resources are trustworthy. They could be bullshit. I don’t know if you’ve noticed but there’s a lot of that online.
