It is anybody’s guess that a book based on fictional genre will sell higher than non-fiction books. But the researchers have managed to get to the nitty-gritty of this situation and have managed to find a secret formula of some kind. The researches heavily analyzed the New York Best Seller List and the data provided by it for the years of and between 2008-2016. This has led them to believe that even though people prefer to buy fiction books out of the whole thought of escaping reality, surprisingly, it is the non-fiction books that manage to retain their titles for a longer period of time like Unbroken by Laura Hillenbrand which made it to 203 weeks of remaining on the bestseller list, higher than any other book in the data.
Fiction genres like mysteries and thrillers make high sales initially, especially when released around festive season. So authors make a smart decision to release their books around Christmas to get a jumpstart of sales.
Another general observation was that general fiction and biographies are more likely to make to the bestseller list over other genres.
Albert-Laszlo Barabasi, a professor at Northeastern University found a universal pattern to book sales. Apparently, all hardcover bestsellers follow the same course of sales pertaining to the same factors. With this analysis, it allowed them to predict sales of a book in its early days of release.
Books have no gender, yet there is a gender disparity that follows amongst non-fiction bestseller authors. Men wrote most non-fiction bestsellers. Women wrote most books under the romantic category, but they found no gender disparity in best-selling fiction authors.
