  skos:definition "Robert Martinson was a correctional researcher who became famous following the publication of a provocative 1974 article on correctional treatment entitled “What Works? Questions and Answers About Prison Reform,” in which he concluded that nothing works to reform and rehabilitate criminals. Although the phrase “Nothing works” became synonymous specifically with Martinson, he was actually a member of a research team that included Douglas Lipton and Judith Wilks, themselves well-regarded scholars in the field of corrections.
