Random selection is difficult to achieve because it involves selecting participants from the population of interest in a way that gives each individual an equal chance of being chosen. This can be challenging because it relies on having a complete and accurate sampling frame and the resources to actually select participants randomly. While participant pools at universities may provide a diverse sample, they are not necessarily representative of the population as a whole and may not achieve true random selection. Random selection is crucial for external validity as it increases the likelihood that the sample is representative of the population, and therefore the results can be generalized to the larger population.
