Homogeneous selection is the term that describes the decrease in the ability of the experimenter to generalize his findings. This happens when subjects are selected on certain criteria that make them similar to each other, which reduces the variability in the sample and limits the ability to make generalizations beyond that specific sample. Random assignment, randomized matching, analysis of covariance, and use of subjects as their own controls do not necessarily have this effect on generalization.
