It is easy to find articles and guides designed for laypeople. If you know the right keyword, it is just as easy to find professional/expert level papers and articles. I have noticed that this is the case across fields. Is that what other folks experience? Where do you go for information when laypeople articles are too basic, but every expert level article is beyond you?
Books from the local library. Most non-fiction is written to be digestible by the general public, whereas published papers will assume a lot of preexisting knowledge in the audience.
Many books are not written too differently from the articles for laypersons, but a book has your attention for 5-10 hours as opposed to 5-10 minutes with an article. All that extra time allows for elaboration on the nuance and context that matters for meaningful discussion about a topic.
Good point. I guess to the same end you could read straight through some subject specific blogs.
