Posts like these are really helpful, thanks! Especially since, in my opinion, at least, a lot of the new English nonfiction books that come out nowadays are 90% fluff and 10% actual material. Many of them seem to be filled with anecdotes that often ramble on and on, making them a chore to read. Basically, 30 pages worth of material turned into a 300 page book. And worse, ALL of them are "best-sellers" with raving reviews from supposedly big media outlets adorning their back pages...

Even worse, a lot of them cannot be trusted... Atleast in Japan, I've seen many books on the bookshelves of big bookstores with clickbaity titles like "The Real Effects of the COVID-19 vaccine! Will you be safe after 2 years!?" written by "reputed doctors" who have a dubious history of peddling weird things.

I have, in principle, stopped buying and reading these nonfiction books unless and until they were written atleast 30 years ago, either written by people on the level of Richard Feynmann in their field, or have a reputable track record and enough (preferably decades) experience about the topic they're writing. This filters out 99.99% of the books flooding the market today. I still run into weird things though.
