To find out, I speak with Maurice Nieuwland, PR manager at Bol.com and Kees Visser, owner of Managementboek.nl . Nieuwland confirms that positive reviews influence the sales of books. He also indicates that a single negative review in a list of positive reviews does not have much influence on the sales of that book. He also tells me that a book with many negative reviews clearly sells less. The findings of Bol.com therefore confirm those of the Yale research.
