Volunteer samples are not preferred to random samples because they introduce bias into the sample. Volunteers may have different characteristics or motivations than non-volunteers, leading to a non-representative sample. Random samples, on the other hand, ensure that every member of the population has an equal chance of being selected, making the sample more representative and generalizable to the population.
