In the labyrinthine corridors of academic research in the humanities and social sciences, navigating the vast array of methodologies, theories and scientific debates can be a daunting task for doctoral students and researchers alike. "Guide Pratique pour la Réussite en Sciences Humaines et Sociales" (Practical Guide to Success in the Humanities and Social Sciences) has emerged as a reference, offering a structured approach to dissecting and implementing research methodologies adapted to these fields. In this book dedicated to research methods in the humanities and social sciences, we explore the essential foundations for carrying out rigorous and fruitful studies. By presenting the different methodological approaches used in these fields, we highlight the crucial importance of methodology in guaranteeing the validity of the results obtained.
