What is their source that the non-fiction book market is collapsing? Their entire premise seems to come down to the fact that non-fiction in 2025 took a smaller share of the top 25 best-selling, hardcover books compared to 2015. It's baffling enough to draw any conclusions from the top 25 of anything, but then to narrow down to hardcover disregards any confounding effects of preferences in format. On top of that they seem to be strangely unaware of this whole phenomenon called ebooks that has been taking the market over by storm.

Besides, non-fiction isn't analogous to fiction, it's not a useful category even. The subset of people who may read biographies may be very different from those who may read popular science or those who read self-help. There is no common denominator encompassing all of these other than the fact that it is a written medium. Fiction is different this way that it is a creative expression often read for the sake of reading and the point is not so much to reach the end. What would be more useful to see is the trend of specific categories of non-fiction over time and which ones are growing and which ones are not.

Perhaps in some ironic way, this article demonstrates why interest in non-fiction may be declining. When you take a singular, weak data point and stretch it over 5 pages saying the same thing, to create a complete non-issue over something that concludes nothing of significance by the end, you have to wonder if one would want to read more of such spiel.
