My research project, that is funded with a NWO Research Talent Grant, focuses on short-term and long-term effects of justification on self-regulation in both health and consumer behavior. This research challenges the long-held assumption that rational, reflective decision making produces behaviors that are in line with long term goals, whereas emotional and impulsive decisions go hand in hand with self-regulation failure. That is, people may deliberately set aside their long-term goals, especially when they have a justification to do so. This research expands on previous research on self-licensing as it specifically examines the long-term effects of justification on indulgent behaviors like (over)eating and excessive buying. In my studies, I use different methods, including vignettes, lab experiments, and experience sampling.
