Pippa Wright, publishing director at Penguin Life, has a word of caution: non-fiction “has always been boom and bust. At the point it goes up, everyone says, ‘No one is interested in fiction, they want answers.’ And then romantasy goes up and everyone wants escapism.” According to NielsenIQ BookData for the UK, although sales have declined from their 2022 peak, they remain significantly higher than in 2015. Wright thinks one kind of self-help has “probably gone”: the “prescriptive book with five bullet points, with information that is summarised very easily... If it can be summarised in a paragraph, then why buy the book?”
