Although the profession of sensitivity reader is booming in the United States, it is still marginal in France. Based on semi‐directive interviews conducted with fourteen professionals involved in the field (sensitivity readers, editors, literary agents), we propose in this article to better define the specificities of this emerging activity from the point-of-view of those who are called upon to practice it or who promote it. We shed light on questions concerning the emergence of a certain 'editorial knowledge-reading', where discriminatory real-life experience and the affirmation of a 'situated knowledge' are at the core of the expertise. We conclude with the role of the editor as an intermediary who seeks to promote a practice that is still rendered invisible in publishing houses.
