Research suggests that not all individuals self-assess their CQ learning similarly. This exploratory study aims to identify systematic inter-individual differences in self-assessed CQ development arising from environmental sensitivity, a relevant trait given that research estimates that 20–30% of individuals are highly sensitive. Design/methodology/approach: This study examines the contribution of an intercultural learning program to CQ development. It draws on survey data collected from all participants in multiple cohorts over 11 years. The participants were highly qualified junior employees representing 25 countries, with 96% from Europe. Data were gathered prior to and following program participation to evaluate changes in self-assessed CQ. Findings: Results indicate that participants with greater environmental sensitivity reported lower self-assessed CQ development. Team size moderated this relationship: the negative association was significant in dyads, but not in triads or quads. Higher levels of prior international experience did not significantly affect the outcome. Originality/value: The study contributes to the understanding of CQ development by highlighting the role of environmental sensitivity, an often-overlooked trait, and it critically assesses the validity of the prevailing evaluation of the effectiveness of CQ learning based on self-assessments in both research and practice. The results offer insights for the design of CQ learning programs and underscore the need to consider the unique challenges faced by environmentally sensitive learners in enhancing their CQ.engCultural intelligenceSelf-assessmentIntercultural learningEnvironmental sensitivityTeam sizeInternational experience650articleurn:nbn:de:bvb:473-irb-113014x
