From lab to life: Decoding the predictive power of present bias on adolescent self-control behaviors

Abstract

This research examines the external validity of laboratory-measured preferences, specifically present bias, in predicting real-life adolescent behaviors. Rooted in the broader debate in experimental economics, we investigate the transferability of lab results, especially in relation to self-control manifestations. Engaging approximately 200 adolescents aged 14 to 19, we assessed present bias through standard intertemporal monetary decisions in a lab setting. Our findings indicate a divergence in the predictive power of laboratory observations. In health-related behaviors, significant correlations were observed between laboratory measurements and BMI, but not with exercise frequency. Meanwhile, academic behaviors such as attendance in self-study courses and late homework submissions were strongly associated. This study sheds light on the nuanced applicability of laboratory-derived preferences in real-world contexts, emphasizing the need for domain-specific considerations.
