External Validity Conference

April 3–4, 2023

Toulouse, TSE/IAST Building


Background and objective

As scholars in numerous fields have begun to care more about internal validity, causality, and replication, the topic of external validity–how inferences generalize and transport–has gained some visibility. However, scholarly attention on causality has mostly outpaced that on external validity. While the recent economics Nobel prizes for work on experiments (2019) and natural experiments (2021) are undoubtedly well-deserved and important, there needs to be a similar revolution on external validity to ensure that study findings apply beyond the specific contexts at hand. Otherwise, the extent to which humans can truly learn from science will necessarily remain limited. The present conference aims to respond to this necessity and brings together scholars from various fields to present the latest work on external validity.
