Random assignment can affect external validity, which refers to the extent to which the results of a study can be generalized to other situations and to other people. While random assignment is crucial for establishing internal validity by ensuring that each participant has an equal chance of being assigned to any group, thereby reducing selection bias and allowing for causal inferences, it might limit the generalizability of the findings if the sample does not accurately represent the broader population.
