    Ce document résume les différents chapitres d’une thèse de doctorat sur le comportement de réponse des consommateurs soumis à un questionnement dans le cadre de recherches ou d’études marketing. Le biais du répondant se définit comme l’erreur de mesure résultant de l’adoption d’un comportement de réponse spécifique par le consommateur interrogé, s’il croit avoir discerné, même partiellement, l’objectif du questionnement. La littérature en psychologie expérimentale et en comportement du consommateur ainsi qu’une étude exploratoire qualitative permettent d’expliquer le comportement de réponse sous la forme d’un modèle de traitement de l’information qui permet d’identifier le biais du répondant. Cette approche séquentielle a permis de développer avec rigueur (ACP, AFC, MTMM) des outils de mesures regroupés au sein d’un questionnaire de détection du comportement de réponse. Enfin, trois études empiriques conduisent à évaluer l’ampleur du biais du répondant dans la collecte de données et son incidence directe sur l’analyse statistique de ces données. Les effets de variables de la situation de questionnement et les liens entre comportement de réponse et variables caractérisant l’individu (anxiété d’être évalué et traits de personnalité) sont aussi explorés. This paper presents a summary of a doctoral thesis that deals with the issue of human behavior during a marketing quantitative study. Demand bias is defined as the error resulting from the adoption of a specific response behavior by the person questioned, if he or she believes to have identified the purpose of the inquiring, even partially. Psychological and consumer behavior literature and a first empirical study show that response behavior can be explain through an information processing model that allows for identification of biases. Measuring tools (evaluation scales and questions) were rigorously developed (PCA, Confirmatory Analysis, MTMM) and gathered in a questionnaire designed to classify biases. Three empirical studies highlight the means and effects of the demand bias and examine the exogenous and endogenous factors that influence the mediation of the demand bias
