The claim is difficult to test because it is not a valid comparison to have hypnotized subjects refuse to do something that they would not be willing to do ordinarily, as there is no way to know what someone would or would not do ordinarily. Therefore, the best comparison would be to test whether hypnotized subjects are more likely to do something dangerous or immoral compared to non-hypnotized individuals. However, even this comparison is difficult to test as it would be unethical to ask people to do something dangerous or immoral even for the purposes of an experiment. Therefore, the claim that people will refuse to do anything under hypnosis that they would not be willing to do ordinarily is difficult to test.
