The experiment lacks random assignment, meaning that the groups of younger and older workers were not selected at random. This could result in bias and affect the validity of the results. Additionally, the experimenter's observations cannot be blind because they are aware of which workers are allowed to use the water cooler, which could also introduce bias into the results.
