An academic study confirms what you already suspected. From the Ottawa Citizen:
University professors have long suspected that students they assign a low grade get revenge by giving them a lousy rating on university evaluations or popular online sites such as ratemyprofessors.com. Now, new research by University of Ottawa professor Tracy Vaillancourt has backed up those suspicions.
In the first study of its kind, Vaillancourt — the Canada Research Chair in Children’s Mental Health and Violence Prevention — found that students who received poor grades were 10 to 19 times more likely to make negative comments about their evaluator than those who received high grades.
The article describes the methodology.
