 In his commencement address, Richard Feynman stated his belief that the antidote to both cargo cult science and pseudoscience is scientific integrity, which he describes as, "a kind of leaning over backwards" to make sure scientists do not fool themselves or others.According to Feynman an ethical scientist must make the extra effort to ensure that their methods and results are transparent, allowing other people to accurately appraise and understand the scientist's research.Feynman uses the case of a Wesson cooking oil advertisement as an example of an unethical and deceptive use of science that delivers nothing of value.
