The number of ears on individuals is a highly consistent trait across the human population, typically two per person, showing very little variability. In contrast, intelligence, as measured by IQ tests, can vary significantly among individuals, including professors. Therefore, assessing the intelligence of all professors based on one professor's IQ test result would not provide a reliable or accurate measure of the group's overall intelligence.
