replicating the study using less common names on the resumes would not increase the external validity as it does not address the issue of the non-random sample and lack of diversity in the original sample. Instead, it only addresses the issue of bias against mothers based on their names. Conducting a field experiment or qualitative interviews, or replicating the study on a more diverse sample would be more effective ways to increase external validity.
