Final answer:
The statement "Doctors are greedy" is primarily an example of thinking in all-or-nothing terms.
Step-by-step explanation:
The statement "Doctors are greedy" is primarily an example of thinking in all-or-nothing terms. This type of thinking involves perceiving things as either entirely good or entirely bad, with no middle ground or nuance. By making a sweeping generalization about all doctors and labeling them as greedy, the statement demonstrates a lack of consideration for the diversity and individual characteristics of doctors.
