This was a field experiment because the variables were manipulated by Judy in a natural setting, which was the bus stop. She did not randomly assign participants to conditions, but this is a common limitation of many field experiments. The study focused on external validity by studying line-joining behavior in a real-world setting, rather than a laboratory.
