Plus reading is competing with all the other ways to spend time. Podcasts are great for nonfiction. Substack and blogs are a much better format for many ideas. Then there's YouTube, and many ways to spend time that aren't ingesting non-fiction.
Besides, a lot of non-fiction just isn't that great. Many books should have been a blog post. These books are rarely a rewarding experience for me, unless it's from a rare combo of historian and good writer.
> the sensibility of nonfiction market is far more catered to men
The book industry is three quarter female. In my experience, book stores visibly cater to a female demographic (featured books, general selection).
