In this context, the researchers are specifically interested in identifying if a particular outcome (reaction time less than 0.05 seconds) is possible at all, rather than generalizing this finding to a larger population. Therefore, the focus is on the existence of a specific case rather than the average or general case, making random sampling less critical for the study's goals.
