The scientist had not actually sorted the mice by intelligence. The students rated the ""highest intelligence"" group of mice as the best maze solvers and the ""lowest intelligence"" group as the worst maze solvers. What was the scientist trying to demonstrate by doing this experiment?Experimental subjects should never be put into groups. Mice should not be judged by their intelligence. Higher intelligence mice are better maze solvers. People can introduce their own biases into an experiment.
